NB slide guides are high-precision and high-rigidity linear bearings designed to utilize the
motion of rolling elements. They have numerous advantageous characteristics including
low friction, no stick-slip, and smooth linear motion even under high load conditions. Since
they can maintain their high-efficiency and high-functionality characteristics for an
extended period of time, they meet a wide range of needs, from general industrial to
precision machinery.

ACCURACY MEASUREMENT METHOD
The accuracy of slide guides is measured by fixing the rail to the datum base. The accuracy is expressed in
terms of the average value at the center portion.
Dimensional Tolerance and Paired Guide
Difference:
The accuracy of the slide guide is obtained by
measuring the height, H, and width, W, as shown in
Figure A-1. The dimensional tolerance is measured
for each of the blocks attached to the rail and is
expressed in terms of the deviation from the
reference value. The paired-guide difference is
obtained by measuring the blocks attached to the rail
and is expressed in terms of the difference between
the maximum and minimum values.
Motion Accuracy:
The rail is first fixed to the reference base. The
motion accuracy is obtained by measuring the
difference in the indicator readings when the block is
moved along the entire span of the rail.
Notation for Number of Rails and Paired
Guide Difference:
When more than two rails are used in parallel, the
guide difference must be measured on more than
one block. For measuring the height, H, the number
of rails can be specified by simply indicating the
necessary number of rails in the part number call-out.
For measuring the width, W, contact NB.
Note When four rails are used as illustrated in Figure
A-3, W4 should be specified in the call-out. Please
indicate the number of rails when ordering.

RIGIDITY AND PRE-LOAD
The rolling elements of the slide guide deform
elastically due to the applied load. The amount of
deformation depends on the type of rolling element. It
is proportional to the 2/3rd power for ball elements.
For rollers, it is proportional to the 0.9th power. In
either case, the amount of deformation decreases as
the applied load increases. Greater rigidity is
achieved by applying a pre-load.
A pre-load causes internal stress within the slide
guide, resulting in some reduction in lifetime.
However, when the part is used under shock or
vibration loading conditions, a pre-load will absorb
the load and will actually help lengthen the life of the
part. Because the pre-load causes elastic
deformation of the rolling elements, it becomes less
tolerable to the installation dimensional difference.
Extreme care should be exercised in machining the
installation surface.
Three primary ranges of pre-loads are available from
NB: normal, light, and medium. This allows the user
to select the appropriate level for the application.

RATED LOAD AND RATED LIFE
Loading Direction and Rated Load:
A slide guide experiences load and moment, as shown in Figure A-5. For each load and moment, the Basic load
rating and allowable static moment are defined.

Rated Life Calculation:
Two types of rolling elements are used in NB slide
guides: ball or roller elements. There is a different
equation for calculating the rated life of each type.
For ball element slide guides (types SEB, SGL and
SGW), the equation is:
3
L= 50(6) fc C
fw P
For roller element slide guides (type SER), the
equations is:
10/3
L= 50(7)

fw P
L : travel life (km) fc : contact coefficent
fT : temperature coefficent fw : load coefficent
C : basic dynamic load rating (N) P : load (N)
Refer to page Eng. 5 for a description of each coefficient
The contact coefficient is used when two or more slides are used in close
proximity to each other.

Mounting Surface Shape and Accuracy:
NB slide guides are designed and fabricated to be
accurately mounted by attaching them to a machined
mounting base. One approach is to provide a
shoulder on the mounting surface and align the
reference surface of the rail or block against this
surface (Figure A-7). To avoid corner interference, an
escape groove should be provided at the shoulder
corner or the radius of the shoulder corner should be
smaller than the radius of the slide guide corner. The
accuracy of the rail surface affects the accuracy of
the machinery or other equipment along with the
slide guide motion accuracy. The accuracy of the
mounting surface should be equivalent to that of the
desired slide guide motion accuracy. The specified
pre-load may not be achieved due to deformation of
the block, for example, the mounted block surface is
not flat. Refer to Figure A-8. Careful attention should
therefore be given to achieve the specified flatness.
Reference Surface Indication:
Reference surfaces are provided to enable accurate
and simplified mounting. They are placed in the same
direction on the block and the rail, as shown in Figure
A-9. They are located on the side opposite to the NB
mark.
Depending on the mounting arrangement, the
standard reference surface may not ensure mounting
accuracy (for example, 1 rail sideway or 2 rails
opposing, page A7, Figure A-6). In such cases, NB
can provide a reference surface on the opposite side.
This should be specified when ordering.

Mounting:
In general, a slide guide is used with 2 rails in parallel. In that case, one rail is on the so-called reference side and
the other is the so-called adjustable side.
Applications where shock/vibration loading and
high load are involved and high accuracy is required.
The effect of shock and vibration on accuracy is
eliminated by mounting on the slide guide a side
piece, which is typically a side plate (Figure A-10),
tightening set screws (Figure A-11), or a tapered
gib (Figure A-12).
Figure A-10 Mounting of Side Plate
reference side adjustable side
Provide an escape groove in the side plate, and push slightly protruding
portion from the bed table.
Applications where light load and low speed are
involved.
Figures A-1315 show the mounting methods
when high accuracy is not required or the load
capacity of the slide guide is sufficient due to a light
load or low speed. In these cases, a side piece or
reference surface may not be required.
Figure A-13 Without Side Piece
reference side adjustable side
Figure A-11 Mounting of Tightening Set Screw

Because space is limited in the guide rail portion, small screws must be
used. Use as many screws as necessary for the length of the rail.
Figure A-12 Mounting of Tapered Gib
reference side adjustable side
By rotating mounting screws of the tapered gib, the gib applies a side
force to the slide guide. The groove shape and surrounding dimensions
must be carefully designed to achieve the desired force.

Mounting Method:
When reference surfaces are provided for both the
table and the base, use the following procedure to
mount the slide guide.
1. Remove burrs, scratches, dust, etc. from the base
and table. Apply a low viscosity oil to the base and
the table. Place the slide guide on the base carefully.
Temporarily fix the rail mounting bolts.
2. Tighten the screw for the side piece so that the
installation reference surface and the rail reference
surface are in contact. If a side piece is not provided,
use a C clamp to position the mounting reference
surface and the rail reference surface so that they
contact each other.
3. Tighten the mounting bolts to the specified torque,
and complete the mounting of the rail. The rail is
designed so that its accuracy is optimum when the
bolts are tightened to the specified value. Refer to the
recommended torgue table for each product type for
the specified torque.
4. Repeat steps 2 and 3 for the rail on the adjustable
side.
5. Move the blocks at the mounting location of the
table, and place the table softly. Then slightly tighten
the screws.
6. Position the reference surface of the block against
the table. Tighten the mounting screws in a diagonal
sequence.
7. Repeat steps 5 and 6 for the block on the
adjustable side.
A-10
Figure A-16 Mounting Using Reference Surfaces
When a side piece is not provided.

When reference surface is not provided on
adjustable side:
When a reference surface is not provided on the
adjustable side, mount the 2 rails in parallel by using
a jig, as mounted in Figure A-17. After mounting the
reference-side guide, install the adjustable-side guide.
When reference surface is not provided on
reference side:
When a reference surface is not provided on the
reference side, mount the 2 rails by using a reference
surface in the vicinity of the slide guide, as illustrated
in Figure A-18.
Temporarily fix the slide guide to the base, and mount
an indicator on the block. Two or more blocks should
be used; they should be fixed using a measurement
plate (Figure A-18).
Place the indicator against the reference surface of
the base. Tighten the bolts from one end of the rail to
ensure straightness. If there is no reference surface
handy, use a straight edge to achieve straightness
(Figure A-19).
Note:
The SEB-A and SER slide guides do not have ball
element retainers, so if they must be removed from
the mounting rail, use a temporary rail to prevent the
ball elements from falling out will be necessary.
Although the SEBS-B SGL and SGW slide guides do
have ball element retainers, the ball elements may
still fall out depending upon how the guide block is
removed from the rail and also the pre-load condition.
The use of a temporary rail is strongly recommended
to prevent damage to the guide block (Figure A-20).
Contact NB for information on temporary rails.

RAIL LENGTH
Guide Rail Length:
Single rails are fabricated as standards to the lengths
shown in the dimensional tables for each type and
series. Unless otherwise specified, the distance to
the first hole from one end of the rail (referred to as
dimension "N") is within the range specified in the
dimensional tables. The guide rail is therefore
fabricated according to the equation given below. For
other than standard dimensional requirements,
contact NB.
L = M P + 2N
L : length (mm) N : distance to the first hole center from the end of the rail
(mm) P : hole pitch (mm) M : number of pitches.
Note:
Slide guide rails are machined with mounting holes
as depicted in Figure A-21 during the initial
fabrication process (before heat treatment).
Specifying a different hole pitch or size will increase
the cost and lead time, so please try to avoid
changing these specifications.
JOINT RAILS
Rails can be joined together to obtain a length which
exceeds the specified maximum standard length.
There are two ways to do this.
Place the joints at the same location for the right
and left rails so as to make the design and
maintenance simple (Figure A-23 ).
Place the joints for the right and left rails at
different locations so that the block does not move
over the two joints at the same time so as to
minimize the effect of the joint on accuracy (Figure
A-23 ).
A-12
Figure A-21 Guide Rail Mounting Hole
Figure A-22 Guide Rail Grinding Method
grinding stone
Please keep the following points in mind when using
joint rails.
To avoid dislocation at joints due to shock loading,
provide a shoulder at the joint on the installation
side.
Use the joint marks provided.
Tightly butt the rails to be joined so that there is no
gap between them.
Notes:
The standard accuracy and pre-load grade are only
available on joined rail systems. The GL type and the
SER type guide series can not be made with joined
rails. Contact NB for further information on joining .

DUST PREVENTION
Seals:
Side seal (Series: SEB, SER, GL, SGL or SGW)
Slide guides with side-seals are used in typical
environments to prevent dust from entering the guide
block from above.
Under seal (Series: GL, SGL or SGW)
Slide guides with side and under seals are used in
more harsh environments or to prevent dust entering
from below.
Double Side Seal Option (Series: GL or SGL)
With this option, the prevention against dust is greatly
improved. Ideal for use in applications where bellows
or covers are not able to be fitted over the system.
No Side Seal (Series: SEB or SER)
When the presence of dust or debris is extremely low
and only minor motion resistance is desired, a No
Side Seal option may be required. Be aware that with
this option, that dust prevention can not be expected.

Scraper Option (Series: GL or SGL)
When the working application environment has
unfavorable foreign matter or debris such as welding
splatter or cutting debris, the Scraper option provides
an effective protective measure for the Guide Block.

Bellows Option (Series: GL or SGL)
This option fully covers the Slide Rail preventing dust,
debris, and other foreign particles from disrupting the
smooth linear motion movement. (Refer to Page A-16
for further details)
Special Cap:
For GL, SGL and SGW guides, special rail mounting
caps are available to prevent dust from entering the
installation mounting holes. These caps are installed
after the rail is installed by using a jig and slowly
inserting them into the holes until their top surface is
flush with the rail surface.

For corrosion resistance, the SEB and SER guides are available in stainless steel material option. Raydent
surface treatment can be specified for the GL, SGL and SGW guide series. This treatment is suitable for
applications where corrosion resistance is required or periodic lubrication is difficult.
LUBRICATION
Lithium soap grease is applied to NB slide guides before they are shipped so that they are ready for immediate
use. The same type of grease should be added periodically depending on the operating conditions.
For GL, SGL, and SGW types, a Fiber Sheet is available which significantly extends lubricant replenishment
intervals. Refer to page A-19 for details.
For use in clean rooms or vacuum environments, slide guides without grease are available. Slide guides
lubricated with customer specified grease for special applications are also available. Please contact us if you
need such products.
NB also provides low dust generation linear system lubricant. Please refer to page Eng-20 for further details.

FIBER SHEET
For the NB slide guide GL, SGL, and SGW types, fiber sheets are available. The sheet significantly extends
lubricant replenishment intervals and has an excellent durability even under harsh conditions with dust, which
absorbs lubricant. Embedded in a block body, as shown in Fig.A-31, it does not change the length of the block. In
addition, the fiber sheet does not require any change in mounting method, which allows replacement with
existing products without a design change.
Figure A-31 Detailed View of the Fiber Sheet
A-18
Fiber Sheet

Simplified lubrication management
A-19
NB's fiber sheet is material with a porous structure containing the lubricant oil. The oil is supplied to the ball
elements at the proper time and in the proper amount by the principle of capillarity, greatly increasing the
intervals between when oiling is required.

The SEB type slide guide is a linear motion bearing in which the ball elements roll along
two tracking grooves. This is the smallest and lightest slide guide series offered by Nippon
Bearing. The compact design allows for the size and weight of machinery and other
equipment to be reduced.
STRUCTURE AND ADVANTAGES
The SEB type slide guide consists of a rail with
precisely machined raceway grooves and a block
assembly consisting of the main body, return caps
and ball elements. Side-seals are available as an
optional feature.
Retained Ball:
With the retained balls, the SEBS "B" type block is
able to be removed from the guide rail, simplifying its
installation and resulting in lower assembly costs.
All Stainless Steel Type:
By using Stainless Steel for the return caps, the
SEBS "BM" type is constructed from only Stainless
Steel making this the ideal choice for special
environments such as high temperature, clean room,
or vacuum applications.
Figure A-34 Structure of SEB Type Slide Guide
Miniature
SEB Type
A-20
Moment Resistant:
A wide block "WA" type, a long block "AY" type, and a
wide/long block "WAY" type are moment resistant
slide guides available. One of these should be
suitable for any demanding operating condition.
Tapped-Hole rail Types:
Slide guides with clearance holes are standard and
tapped holes are available upon request.
Anti-Corrosion:
The SEBS type slide guide uses Martensite stainless
steel which is highly resistant to corrosion and may
be used in hostile environments.

The NB SER type slide guide is a linear motion bearing utilizing the rotational motion of
precision rollers placed in two rows. Despite its compact shape, it can be used in various
applications requiring high load capacity.
The NB SER type slide guide consists of a rail with
two precision-machined raceway grooves and a block
assembly. The block assembly consists of a main
body, rollers, and bottom roller retainers. All of these
components are made of metallic materials.
High Load Capacity and Long Life:
Since roller elements are used, the contact surface is
large which provides a high load capacity and long
travel life.
Compactness:
Since a cross roller method is utilized, only two
raceway grooves are necessary and presents a very
compact package.

Moment Resistant Type:
The wide block design (WA Type) has an extremely
high moment loading capacity. This will allow for
single shaft designs in the most hostile environment
applications.
Rail Bolt Hole Types:
SER type rails with counterbore bolt holes (standard)
and optional tapped mounting holes (N-type) are
available enabling various installation methods.
All Stainless Steel:
Since all the components for the SER type guide are
made of metallic materials, stainless steel provides
excellent corrosion and thermal characteristics. The
SERS type slide guide is ideal for clean-room or
vacuum applications.

Low Noise:
By incorporating a ball cushion between steel balls,
the metal contact between the steel balls is
prevented, which allows for a reducion in noise levels.
(See the noise data in Fig. A-44, page A-53.)
Can Significantly Extend Lubricant
Replenishment Intervals:
A lubricant-containing fiber sheet incorporated in the
block supplies appropriate amount of lubricant to the
raceway grooves at appropriate intervals, which can
significantly extend the lubricant replenishment
interval.
A-42
GL TYPE
The NB slide guide GL type realized low noise with a ball cushion embedded between the
steel balls and significantly extended lubricant replenishment intervals by the use of fiber
sheet. In addition, its compact size as well as high load capacity allows for the size and
weight of machinery and other equipment to be reduced.
STRUCTURE AND ADVANTAGES
The GL type slide guide consists of a rail with 4 rows of precisely machined raceway groove and a block
assembly consisting of the main body, steel balls, ball cushions, a retainer, a fiber sheet, and return caps.

High Load Capacity and Long Life:
With large-diameter steel balls employed, this slide
guide has a higher load rating and a longer life
compared to low-noise guides offered by other
companies.
(See the load rating comparison data in Fig. A-44,
page A-53.)
Omni-Directional Load Capacity:
The steel balls are positioned at 45 o contact angle so
that the load capacity is equal in four directions
(above, underneath, right and left).

SGL slide guides consist of a rail with four precisionmachined
raceway grooves and a block assembly.
The block assembly consists of the main body, ball
elements, retainers, and return caps.
High Load Capacity and Long Life:
The use of larger ball elements and a raceway with
grooves machined to a radius close to that of the ball
elements increases the area of the contact surface.
The results are load capacity and provides longer life.
Low Wear:
Because a 4-row/2-point contact design is used, low
wear and stable motion characteristics are achieved
even under a pre-loaded conditions.
Omni-Directional Load Capacity:
The ball elements are positioned at 45contact angle
so that the load capacity is equal in four directions
(above, underneath, right and left).
A-60
SGL TYPE
The SGL slide guide is a linear motion bearing utilizing the rotational motion of ball
elements along four rows of raceway grooves. It can be used in various applications due to
its compactness and high load capacity.
STRUCTURE AND ADVANTAGES
Figure A-60 Structure of SGL type Slide Guide
rail
return cap
side seal
block
Absorption of Mounting Dimensional Error:
Because the ball elements are positioned to increase
their self-aligning characteristics, the dimensional
error caused during installation is absorbed.
Anti-Corrosion Specification:
The rail and block assembly may be Raydent treated
to increase the corrosion resistance. This treatment
is standardized with the symbol "RD", and suitable for
use in clean room applications.
Dust Prevention:
Side seals are provided as a standard. To improve
the dust prevention characteristics, underseals and
special rail mounting caps are also available.

SGL slide guides are available with a standard pre-load(no suffix), light pre-load(T1), and medium pre-load(T2).
Slide guides with most commonly used lengths are
available as standard. Unless otherwise specified,
the distance to the first mounting hole (N) from one
end of the rail will be located within the range listed in
Table A-31 for slide guides that have a non-standard
length satisfying the following equation.

MOUNTING
Slide guides are generally mounted by pushing the
reference surface of the rail and block against the
shoulder of the mounting surface. An escape groove
should be provided at the corner of the shoulder in
order to avoid interference with the corner of the rail
or block.
The bolts used to secure the rail should be tightened
using a torque wrench. The recommended torque
values are listed in Table A-32.

SGW slide guide consists of a rail with four precisionmachined
raceway grooves and a block assembly.
The block assembly consists of the main body, ball
elements, retainers, and return caps.
High Load Capacity and Long Life:
The raceway grooves are machined to a radius close
to that of the ball elements. The larger contact
surface results are high load capacity and provides
longer life.
High Allowable Moment:
Its wide profile enables it to sustain high moment
loads, making it suitable for single-rail applications.
Omni-Directional Load Capacity:
The ball elements are positioned at 45 o contact angle
so that the load capacity is equal in four directions
(above, underneath, right and left).
A-76
SGW TYPE
The SGW slide guide is a linear motion bearing utilizing the rotational motion of ball
elements along four rows of raceway grooves. Its low height and wide profile makes it
suitable for single-rail applications.
STRUCTURE AND ADVANTAGES

block
Smooth Motion:
The large number of ball elements produce a smooth
rolling motion.
Anti-Corrosion Specification:
The rail and block assembly may be Raydent treated
to increase the corrosion resistance. This treatment
is standardized with the symbol "RD", and suitable for
use in clean room applications.
Dust Prevention:
Side seals are provided as standard. To improve the
dust prevention characteristics, under-seals and rail
mounting caps are also available.

MOUNTING
Slide guides are generally mounted by pushing the
reference surface of the rail and block against the
shoulder of the mounting surface. To avoid
interference between the shoulder and the corner of
the rail or block, the shoulder should be fabricated
with dimensions smaller than those listed in Table A-
39. The bolts used to secure the rail should be
tightened to a certain torque using a torque wrench.
The recommended torque values are given in Table
A-38. Please adjust the torque depending on the
operating conditions..

The NB ball spline consists of a spline shaft with
raceway grooves and a spline nut. The spline nut
consists of an outer cylinder (main body), retainer,
side rings, and ball elements. Designed and
manufactured to achieve a reliably smooth motion.
High Load Capacity and Long Travel Life:
The raceway grooves are machined to a radius close
to that of the ball elements. The large ball contact
area results in high load capacity and long travel life.
Wide Variety of Configurations:
16 shaft sizes with diameters from 4mm to 100mm
are available. Seven different types of nuts are
available: cylindrical types (SSP/SSPM), flange types
(SSPF/SSPT), and block types (SPA/SPA-W/SSPB).
Material option of Stainless steel(440C or equivalent)
is also available. They can be specified to suit various
applications.
The NB ball spline is a linear motion mechanism utilizing the rotational motion of ball
elements. It can be used in a wide variety of applications including robotics and transport
type equipment.

Transmission of Torque:
NB ball splines can sustain loads in several directions
simultaneously . They can be used as a single shaft
system and can transmit (or resist) torque.
Ease of Additional Custom Machining:
Since a round shaft with raceway grooves is used,
NB ball spline shafts can be machined easily to
customized specifications.

LIFE CALCULATION
Because ball elements are used as the rolling
elements in ball splines, the following equations are
used to calculate the life of ball spline systems.
For radial load
3
L= 50 fc C
fw P
For torsional load
3
L= 50 fc CT
fw T
The performance of a ball spline system is affected
by the operating condition and environment of the
application. The operating conditions should therefore
be carefully taken into consideration.
Dust Prevention:
The invasion of foreign particles and dust may affect
the motion characteristics and shorten the life of a
ball spline. Seals will perform well under normal
operating conditions. However, they may not prevent
the entry of foreign particles in a hostile environment.
When used in such an environment, the ball spline
should be protected using bellows and protective
covers.
Operating Temperature:
The ball retainers used in ball spline nuts are made of
resin, so the operating temperature should never
exceed 80 o C.
B-8

L : travel life (km)

fc : contact coefficient
fw: Load coefficient
C : basic dynamic load rating(N)
P : load(N) CT : basic dynamic torque rating(N-m)
T : torque(N-m)
* Refer to page Eng-5 for coefficients
** The rated load for the commercial spline shaft is approximately 70% of
the standard ball spline shaft.
OPERATING ENVIRONMENT
Figure B-4 Examples of Dust Prevention Methods
bellows cover
Excessive Moment:
The allowable load for ball splines is high, and they
can also sustain high moment load. However, when
the load becomes excessive, the load applied to the
raceway grooves becomes unbalanced and stable
motion may not be achieved. When accuracy is
required, the application of excessive moment should
be prevented by using two or more spline nuts.

LUBRICATION
Both ends of the spline nut have a side-seal as a
standard feature. For the fully ground spline shaft, the
side-seals are positioned against the spline shaft so
as to prevent the lubricant from leaking out of the
spline nut.
Lithium soap grease is applied to NB ball spline nuts
before shipping, so there is no need to apply
lubricant at the time of installation. However, a small
amount of lubricant may be lost during operation, so
the lubricant needs to be replenished periodically.
SPECIAL REQUIREMENTS
NB will fablicate custom shafts, spline nut, surface
finish, etc. to meat customer requirements.
For hollow spline shafts, recommended standard
inner diameters are listed in Table B-9. Contact NB
for details.

Fit:
A transition fit between an SSP/SSPM-type spline nut
and its housing bore is used to minimize the
clearance. If high accuracy is not required, then a
clearance fit is used.
For the SSP/SSPM type spline nuts, if only a light
load is to be applied, a hole slightly larger than the
outer diameter of the nut will suffice.
Insertion of Spline Nut:
When inserting a spline nut into the housing, use a
jig, example as shown in Figure B-7. Carefully insert
the nut so as not to hit the side ring and side-seal.

Insertion of Spline Shaft:
Insertion of Spline Shaft: When inserting the spline
shaft into the spline nut, ensure that the ball elements
do not drop out. This is accomplished by aligning the
raceway grooves of the shaft with the rows of ball
elements in the nut. Then simply insert the spline
shaft through the spline nut.

The NB rotary ball spline can be used for both rotational motion and linear motion. It can be
used in SCARA robots, the vertical shaft of assembly equipment, and tool changers and
loaders.
STRUCTURE AND ADVANTAGES
The NB rotary ball spline consists of a spline shaft
and a nut. The nut has a spline portion and a rotating
portion using cross rollers.
Reduced Number of Parts:
Because of the single-body construction consisting of
the rotating portion and the spline portion, the
number of parts is reduced so that the accumulated
error is reduced as well.
Compact and Light:
The cross rollers are directly attached to the ball
spline's external cylinder, resulting in a compact and
light design.

Substantial Reduction in Installation Cost:
The use of cross roller elements keeps the housing
thickness to a minimum, making the ball spline light
and easy to install.
High Rigidity:
The cross roller elements and 4-row ball circuit
structure provides high rigidity in spite of the compact
design.
High Accuracy:
The cross roller elements ensure accurate
positioning in the rotational direction.

PRE-LOAD AND CLEARANCE IN ROTATIONAL DIRECTION
The amount of clearance and pre-load for the spline portion and the cross-roller portion are expressed in terms
of the clearance in the rotational direction and the clearance in the radial direction, respectively. Three levels of
pre-load are available: standard, light (T1), and medium (T2).

MOUNTING OF ROTARY BALL SPLINE
The flange attachment bolts have been pre-adjusted
for smooth rotary movement and should never be
loosened. Shock loading to the flange assembly
should be avoided as this can degrade the accuracy
of movement and deteriorate the overall performance.
Mounting:
When the flange is to be used with a faucet joint (as
shown in Figure B-23) the housing bore should be
machined to a tolerance of H7 and to a minimum
depth of 60% of the flange thickness. If only a light
load is applied to the SPR in operation, the flange
can be used without a pilot end.
When the mounting bolts are fixed, they should be
tightened diagonally in steps with progressively more
torque at each step. A torque wrench should be used
to achieve uniform torque. The recommended torque
values for medium-hardness steel bolts are listed in
Table B-21.
Insertion of Spline Shaft:
When inserting the rotary ball spline shaft into the
spline nut, ensure that the ball elements do not drop
out. This is accomplished by aligning the raceway
grooves of the shaft with the rows of ball elements in
the nut. Then simply insert the spline shaft through
the spline nut.
LUBRICATION
Since NB rotary ball splines are equipped with seals
at both the spline portion and the rotational portion,
the lubricant is retained for an extended period of
time. Lithium soap grease is applied prior to
shipment, so they can be used immediately without
having to apply lubricant. Lubricant should be added
periodically and depending on the operating
conditions.
NB also provides low dust generation grease for the
linear system. Please refer to page Eng-20 for details.
A grease fitting can be installed as an optional feature
however, an oil lubricant should be used for high-

OPERATING ENVIRONMENT
Certain operating environments may prevent the full
functionality of the rotary ball spline from being
achieved expected accuracies. The operating
environment should be taken into consideration when
designing the system.
Operating Temperature:
Resin retainers are used in the rotary ball spline, so
the operating temperature should never exceed 80.
APPLICATION EXAMPLES
ball screw
B-36
Dust Prevention:
The invasion of foreign particles and dust may affect
the motion characteristics of the rotary ball spline and
shorten the travel life. Seals will perform well under
normal operating conditions, but may not completely
prevent the entry of dust in a hostile environment.
When used in such environments, a dust prevention
mechanism such as bellows or covers should be
used to protect the rotary ball spline.

The NB stroke ball spine SPLFS type is a high accuracy linear motion bearing with a limited
stroke, to which both radial load and torque can be applied at the same time. It operates
with extremely small dynamic friction.
STRUCTURE AND ADVANTAGES
The NB stroke ball spline consists of a nut and a shaft both with raceway grooves . Since the retainer in the nut
is equipped with a ball pocket, the steel balls, (rolling elements) do not contact each other, which allows for a
smooth linear motion.
In a linear motion, however, the retainer moves a half of the travel distance. Therefore, the linear travel stroke is
limited up to twice as long as the distance that the retainer can move in the nut. For normal operation, it is
recommended to consider 80% of the maximum stroke shown in the dimension list as an actual travel distance.
Extremely Small Dynamic Friction and Low
Noise:
The rolling elements are separated by the ball
pockets so that they do not contact each other. The
stroke length is limited, but extremely small dynamic
friction and low noise are realized because the rolling
elements do not circulate.
Compact-Size:
With the nut about 20% smaller than existing ball
splines, it contributes to space saving.

All Stainless Steel:
Since all the components are made of stainless steel,
this stroke ball spline has an excellent corrosion
resistance and heat resistance (operating
temperature: -20 to +140). It is ideal for clean-room
or vacuum applications.
Lubrication:
A lubricant groove and two lubrication holes are
provided on the outer surface of the nut, which allow
for an easy designing of lubricant replenishment.

NOTES ON USE
Dust Control:
Since the stroke ball splines are designed and manufactured for operating with an extremely small dynamic
friction resistance, any seal that increases the dynamic friction resistance is not equipped as a standard feature.
If you use this type of spline under unfavorable conditions, contact us and a special seal will be available.be For
use under extremely unfavorable conditions, the stroke ball spline should be protected using bellows and
protective covers.
Retainer Misalignment:
If the stroke ball spline is used at a high speed or with a vertical shaft, or under an asymmetric load or oscillation,
a retainer misalignment may occur. For general operation, it is recommended to consider 80% of the maximum
stroke length shown in the dimension list as a travel distance.
In order to prevent the retainer misalignment, it is also recommended to conduct a full-stroke moving operation
times during use so that the retainer will be relocated to the center.

NB now offers a new standard in linear motion with TOPBALL. The TOPBALL slide bush is a
high performance bushing with three times the load capacity, capable of providing up to 27
times normal travel life of a conventional slide bushing.
TOPBALL is available in a variety of configurations to fit various service conditions. NB's
self-aligning TOPBALL can be designed into many different applications such as factory
automated equipment, machine tools, industrial machines, electrical equipment, optical
and measuring instruments.
In the early stages of NB's development of TOPBALL, careful thought and consideration
was given to such factors as quality, cost, performance and interchangeability. The results
of these efforts are reflected in the TOPBALL features.
TOPBALL FEATURES
1. Increased Load Capacity:
NB's uniquely designed ground load plate provides
circular arch contact to the ball element resulting in a
greater dispersion of the load, enabling TOPBALL to
provide three times the load capacity of conventional
slide bushings.
2. Longer Travel Life:
Dispersed stress on the load plate provides
TOPBALL up to 27 times the travel life of
conventional slide bushings.
3. Self Aligning Capability:
Load plates are thinner at the ends to provide a pivot
point at the center of the plate. The center acts as a
fulcrum to compensate for any slight misalignment
between the shaft and the housing bore that might be
caused by inaccurate machining, mounting errors or
shaft deflection.
Figure C-1 Illustrating circular arch design and ground surface
raceway
Ground surface raceway
Circular arch design
C-2
4. Floating Integral Wiper Seal:
NB's unique floating seal design allows for selfalignment
while maintaining equal and constant
contact to the shaft. Seals do not add to the overall
length of the bushing allowing for more compact
designs.
5. Clearance Adjustable:
TOPBALL load plates are designed to "float" in the
outer sleeve which allows for clearance between the
ball elements and shaft to best suit application
requirements.
6. Cost Effectiveness:
TOPBALL's higher load capability and longer travel
life enables the use of smaller components such as
bushings, housings and shafts, reducing material
cost and the overall cost of the system. Longer travel
life also extends replacement periods and reduce
maintenance cost.

RATED LIFE
The life of a slide bush can be easily calculated with the load rating of the bush, shaft hardness and
applicable load. However, in many cases, slide bushing failure may be caused by improper design
of peripherals, including the shaft and housing, inappropriate mounting or improper operation.
Serious consideration of these peripheral factors, in addition to load rating, are highly
recommended when designing a slide bush application.
Basic Dynamic Load Rating and Life
Expectancy:
The basic dynamic load rating is the load which
allows a rating life of 50km, without changing its
magnitude and direction. The rating life can be
obtained from the following equation.
3 C
L =50 Equation (1)
P
L : travel life (km)
C : basic dynamic load rating (N)
P : load (N)
Figure C-3 shows the relationship between rating life
(L) and load ratio(C/P). In the practical use of a
bushing, other factors that affect the life, such as
shaft hardness and load condition should be
considered. The equation for calculating bushing life
considering these additional factors is:
fH C 3
L=
fw P
50 Equation (2)
fH : hardness coefficient (See Figure C-4)
fw : load coefficient (See Table C-1)
Life time can be calculated by obtaining the travelling
distance per unit of time as follows:
L10 3
Lh= Equation (3)
2LsN160
Lh : life time (hr)
Ls : stroke length (m)
N1 : stroke frequency per min. (cpm)
L : travel life (km)

Load coefficient (fw):
When calculating the bush load, it is necessary to
accurately obtain weight, inertial force based on
speed, moment load and each transition as time
passes. However, it is difficult to calculate those
values accurately because reciprocating motion
involves the repetition of starts and stops as well as
vibration and inpact. A more practical approach is to
obtain the load coefficient by taking the actual
operating conditions into account.
Table C-1: Load Coefficient
OPERATING CONDITIONS

without impulsive shock from outside
operation at intermediate speed
(60m/min.or less) without impulsive shock
operation at high speed (over 60m/min.)
with impulsive shock
Hardness Coefficient (fH):
The shaft must be hardened to over 58HRC when a
slide bush is used. If not properly hardened,
permissible load is lowered and the life of the bushing
will be shortened.

used under the following conditions:
Load per bush: 668N
Stroke length: 0.2m
Rate of cycles/min: 35

From the basic dynamic load of TK25 is 3780N.
hardness coefficient(fH) is 1.0, and the operating
speed can be calculated as 0.014km/min. Therefore,
the load coefficient(fw) is considered as 1.0.

Basic Static Load Rating:
If a slide bush is loaded when it is in a stationary
condition or working at a low speed, a permanent
elastic deformation is formed on the rolling element.
The deformation prevents smooth movement of the
bushing. To eliminate this possibility, the basic static
load rating must not be exceeded.
Relation Between Ball Circuits and Load
Rating:
The load rating of a slide bush varies according to the
loaded position on the circumference. The value in
the dimensional table indicates the lowest load rating
with the load placed on top of one ball circuit. If the
slide bush is used with two ball circuits loaded
uniformly, the value will be greater. Table C-2 shows
the load ratio for the number of ball circuits in each
case.
Clearance and Fit:
An appropriate clearance between the slide bush and
shaft is required in TOPBALL operation. Inadequate
clearance may cause early failure and/or poor, rough
movement. Proper clearance is determined by shaft
diameter and housing bore. Table C-3 and C-4 shows
NB's recommended tolerances of the shaft and
housing bore in order to maintain the appropriate
clearance.

Anti-Corrosive Type:
A special TOPBALL is also available for corrosive
applications. Specify with a suffix "-SK" for either
bushing or slide unit requiring our anti-corrosive type
TOPBALL. The load plates are electroless nickel
plated and use Stainless Steel ball elements. For
"-SK" slide units, all hardware components are of anticorrosive
properties.

Shaft and Housing:
To optimize NB TOPBALL performance, high
precision shafts and housings are required.
1. Shaft: Dimensional tolerance, surface finish and
hardness greatly affect the traveling performance of
the TOPBALL. The shaft must be manufactured to
the following tolerances.
A. A surface finish of 0.4Ra or less.
B. Hardness of 60 HRC or more. Hardness less than
60 HRC decreases the life considerably and reduces
the permissible load.
C. The correct tolerance of the shaft diameter is
recommended on Table C-3 and C-4 (Page C-6).
The NB Slide Shaft is an ideal component
manufactured to these specifications. For details,
please refer to Page G-2 to G-21.
2. Housing: There are a wide range of designs and
manufacturing techniques for mounted housings. NB
pre-engineered slide units are also available. For
proper fit refer to Table C-3 and C-4 (Page C-6).
Mounting:
TOPBALL is designed to be press fitted into the
housing bore. When inserting bushing, however,
don't apply excess force nor shock load which may
cause permanent damage.
Examples of Mounting
Figures C-5 to C-8 illustrate mounting methods as
examples.

Figure C-5 Use of holding plates

The NB slide bush is a linear motion mechanism utilizing the rotational motion of ball
elements. Since linear motion is obtained using a simple mechanism, the slide bush can be
used in a wide variety of applications, including transportation equipment, food processing
equipment, and semiconductor equipment.
STRUCTURE AND ADVANTAGES
The NB slide bush consists of the outer cylinder and
a ball retainer that guide the circulation of the ball
elements, resulting in smooth linear motion.
Compact Mechanism:
The NB slide bush uses a round shaft for the guide,
resulting in effective space utilization, which allows
for compact designs.
A Wide Variety of Shapes and Installation
Methods:
The NB slide bush is available in various shapes,
which make it suitable for various types of
installations : lightweight, standard, clearance adjustable,
open, flange, and double-wide types.
Selection According to Environment:
Standard and anticorrosion NB slide bushes are
available. Additionally, options available are both
metallic retainers suitable for use in harsh environments
and low acoustic, low-cost resin retainers.

These options can be specified according to
application need.
Compatibility:
The NB slide bush is fully compatible with a variety of
shaft types.
Low Friction:
The raceway surface is precision ground. Since the
contact surface between the ball elements and the
raceway surface is minimized, the NB slide bush
provides low friction when compared to other linear
motion mechanisms.
GM type series:
The GM Slide Bush makes efficient use of resin
components making it possible to achieve an overall
weight reduction of 3050% when compared with
the SM Slide Bush.
The ball return section is configured completely in
resin material, which provides for low noise operation.

SPECIFICATIONS
Dimensional Series:
The NB slide bush is available in three primary
dimensional series, each with different dimensions
and tolerances depending on the location of use.
Select the series most appropriate for your location.
Allowable Load:
NB slide bushes are categorized into three functonal
types depending on the number and location of
retainers: single, double, and triple. The single type
uses only one retainer, so when a moment load is to
be applied, the double or triple type should be used.
Material:
The standard NB slide bush uses a bearing steel
outer cylinder. The anti-corrosion NB slide bush uses
Martensitic stainless steel. Seamless type steel
(stainless steel for the anticorrosion type) retainers
and resin retainers for low acoustic operation can be
specified.
Seals:
The seals effectively retain the lubricant within the
slide bush, extending the time between lubrications.
The UU type has seals on both sides. The U type has
a seal only on one side and is available for the
standard, clearance adjustable, and open types. Nitril
rubber, which has low wear and good sealing
characteristics, is used as the seal material.
Resin seals are used for GM type.

LIFE CALCULATION
Since ball elements are used as the rolling element in
the NB slide bush, Equation (6) is used to calculate
the Travel life.
L= 50(6) 3
fHfTfC C
fw P
L : travel life (Km) fH : hardness coefficient
fT : temperature coefficient fW : load coefficient
C : basic dynamic load rating P : load (N)
*Refer to page Eng. 5 for the coefficient.
D-7
If the stroke distance and number of strokes per unit
time are constant, the life is calculated using
Equation (9).
L10 3
Lh= (9)
2sn160
Lh : travel life in time (h) s : stroke distance (m)
L : travel life (Km) n1 : stroke frequency per min (cpm)
In the open type slide bush, an opening is provided to allow the shaft to be supported from underneath. When a
load is constantly applied in the direction of the opening (for example, when used with a vertical shaft or when an
overhang loading is applied), the rated load decreases due to the reduction in the number of rows of ball
elements that are loaded. Therefore, the load rating must be calibrated at the time of design based on the
direction of the loading.

D-8

Fit:
The normal clearances listed in Table D-8 are
generally used for the NB slide bush. The transition fit
is used to reduce clearance and increase accuracy.
Matching the clearance as specified between bush
and shaft is also possible.
The pre-load for the clearance adjustable and open
type slide bush must be adjusted carefully so that
excessive pre-load does not exceed limits, based on
the radial clearances listed in the table.
The flange-type bush is generally inserted into an
installation bore, which is slightly larger than the
outer cylinder. However, if the outer cylinder is used
as the pilot type, H7 tolerance is recommended.
The recommended clearances for the flange type are
listed in Table D-9.
GM Flange type:
GM flange has a reference plane on one side only as
Figure D-8a, do not use the other side as a reference
plane. In case of using the pilot-end flange type,
Figure D-8b shows that both sides can be used as a
reference plane.
H7 is recommended for the housing bore tolerance.

Notes on Installation:
When inserting a slide bush into a housing, carefully
insert it by using a jig to apply a uniform pushing
force at the end of the outer cylinder, as illustrated in
Figure D-9. Motion performance may be diminished if
an excessive force is applied to the resin portion of
the outer cylinder, the side-ring, or the seal.
Ensure that all burrs are removed from the shaft and
carefully insert the bush by aligning it with the center
of the bore. The ball elements may drop out if
excessive force is used during insertion.
When two or more shafts are used, the parallelism of
the shafts will greatly affect the motion characteristics
and life of the slide bush. The parallelism should be
adjusted by moving the slide bush back and forth the
length of stroke to check for freedom of movement
before final fixing of shaft.
LUBRICATION
Grease Lubricant:
Grease should be applied to the internal
components of the slide bush. Grease should be
periodically reapplied depending on the operating
conditions. Reapplication may be done by adding the
grease directly to the internal components or by
using a mechanism similar to that as shown in Figure
D-10. Lithium soap grease is recommended.
A special low dust generating grease for use in clean
rooms is also available.(See page Eng.20) Contact
NB for further details.
Oil Lubricant:
Oil can be applied directly to the shaft or by using a
mechanism similar to that shown in Figure D-10.
Turbine oil (ISO standard VG32-68) is recommended
for highspeed applications.
Lubrication oil holes can be fabricated (see Figure D-
11) in the center portion of the outer cylinder to
simplify oil application. Contact NB for further details.
Dust Prevention
If foreign particles such as dust or grinding chips are
introduced into the slide bush, they will disrupt the
smooth circulation of the ball elements. The NB slide
bush is available with seals as an option. Bellows or
protective covers should be used under harsh
environmental operating conditions.

For a slide bush to continue operating accurately and have a long life, it must be lubricated on a regular basis.
Anti-rust oil is applied to NB slide bush prior to shipment. When slide bushes are delivered, they should be
cleaned with kerosene and dried, then a lubricant should be applied before usage.

NOTES ON HANDLING
The NB slide bush is a precision device and therefore
should always be handled with care. The slide bush
is not designed for rotational motion. When
applications require both rotating and linear motions,
a stroke bush (page F-2), slide rotary bush (page F-
8), or rotary ball spline (page B-32) should be
considered.

A wide variety of linear motion slide units are available. Their high precision blocks
increase the accuracy of machinery and other equipment. The blocks can be constructed of
resin to reduce cost and weight. The use of standard shaft end supports and shaft support
rails simplifies the components. The use of commercial units help to reduce design time
and installation and component costs.

When an open-type slide unit is used with the load
in the direction shown in Figure E-4, the load rating
must be calibrated using the coefficients listed in
Table E-5.

NOTES ON USAGE
Reference Surface:
A reference surface is provided with NB slide units as
a standard feature. Excellent accuracy can be
achieved by simply pushing the reference surface
against the shoulder of the installation surface.
(Excludes RB/RBW/SMP types)
Clearance Adjustment:
The adjustment of pre-load for the slide unit must be
done carefully so that pre-load is not excessive. Care
should be taken not to apply excessive torque when
tightning the screws.
Mounting of RB Type Unit:
RB type unit has a resin housing. Mounting should be
done using the proper torque values given in Table E-6.
Recommended Fit:
A standard grade slide bush is installed in NB slide
units. For clearance and transition fit, g6 and h6
tolerance shafts, respectively, should be used.

The NB stroke bush is a linear and rotational motion mechanism utilizing the rotational
motion of ball elements between an outer cylinder and a shaft. It is compact and can with
stand high loading. The retainer is made of a light metal alloy with high wear resistance.
Smooth motion is achieved under high-speed and high-acceleration conditions. Although
the linear motion is limited to a predetermined stroke distance, the smooth combination of
linear and rotational motions is achieved with very little frictional resistance. The NB stroke
bush may be conveniently used in a variety of applications.
STRUCTURE AND ADVANTAGES
The retainer in the NB stroke bush positions the ball
elements in a zigzag arrangement. The inner surface
of the outer cylinder is finished by grinding, resulting
in the smooth motion of the ball elements. Each of
the ball elements is held in a separate hole and
smooth motion is achieved for both rotational motion
and linear motion. The retainer moves half the
distance of the linear motion, therefore, the stroke
distance is limited to approximately twice the
distance the retainer can travel within the outer
cylinder. The actual stroke should be limited to 80%
of the maximum stroke as listed in the dimensional
tables.

High Precision
High-carbon, chromium-bearing steel is used for the
outer cylinder. It is heat treated and ground to
achieve high rigidity and accuracy.
Ease of Mounting / Replacement
The highly accurate fabrication of the NB stroke bush
results in uniform dimensions, facilitating parts
replacement and housing fabrication.
Light Weight / Space Saving
The use of an aluminum alloy for the retainer and the
thin-wall outer cylinder make the NB stroke bush light
weight and compact.
Lubrication
Lubrication holes are provided on the oil grooves of
the outer cylinder, making it easy to lubricate the SR
stroke bush.

ACCURACY
The accuracies of the SR stroke bush are stated in
the dimensional tables. Since the outer cylinder
deforms due to tension from the retaining ring, the
dimension of the outer cylinder is an average value at
points P, where calculated using the following
equation:
W = 4+ L 8
W : the distance from the end of the outer race to measurement point P
L : the length of the outer race
FIT
The inner contact diameters of the SR stroke bush
are listed in the dimensional tables. The shaft
diameter tolerance should be selected to achieve the
desired amount of radial clearance. High-speed
linear motion can cause the retainer to slip due to
inertial force. An interference fit of 3 to 10 m
RATED LOAD AND RATED LIFE
The relationship between the rated load and life of
the stroke bush is expressed as follows:
3 C
L = P
L : the rated life (10 6 rotations), C : the basic dynamic rated load (N)
P : load (N)
For rotation/stroke combined motion
10 L
Lh =
60(dmn) 2 +(10Sn1) 2 6
dm
The allowable speed for combined rotation and
stroke motion is obtained from the following equation:
F-3
Figure F-2 Outer Cylinder Measurement Points
will compensate for such slip. The fits generally used
between the shaft and the housing are listed in the
table below.

NB's Slide Rotary Series consists of three different types. The Slide Rotary Bush, which
provides both endless rotary and linear motion functions, the Flanged Slide Rotary Bush,
and the Slide Rotary Unit which is assembled using various NB standard housings.
The NB Slide Rotary Series has an idealistic structure, incorporating a combination of linear
and rotary motion. Linear and rotary motion are merged into a single unit resulting in great
space savings compared to the conventional style of Slide Bushings. All three types of the
Slide Rotary Series are available in sizes ranging from 6mm to 30mm. All components in
the Slide Rotary Series are standardized for versatile installation requirements.
STRUCTURE AND ADVANTAGES
NB Slide Rotary Bush is composed of retainer fitted into cylindrical steel outer race and is designed to guide
steel balls for smooth circulation in its retainer. The retainer is also designed to rotate freely towards radial
direction and offers smooth linear and rotary motions.
Smooth Operation
The inner surface of the outer race allows smooth
operation of linear and rotary motions while
maintaining a uniform load distribution.
High Load Capacity
The use of comparatively large diameter steel balls
enhances acceptability of high load capacity.
Smooth Rotation
The positioning of the steel balls in a cylindrical
formation inside the retainer enables a smooth
rotational motion to be achieved independent of the
installation direction.
F-8
Complete Interchangeability
NB Slide Rotary series is completely interchangeable
with SM type Slide Bush, SMK type Flanged Slide
Bush and Slide Units such as SMA(W) type, AK(W)
type and SMP type.

RATED LIFE AND LOADS
The rated life and loads are defined as follows.
Rated Life
When a group of slide rotary bearings of the same
type are used under the same conditions, the rated
life is defined as the total number of rotations made
without flaking by 90% of the bearings.
Basic Dynamic Rated Load
The basic dynamic rated load is defined as the load
with a constant magnitude and direction at which a
rated life of 10 6 rotations can be achieved.
Basic Static Rated Load
The basic static rated load is defined as the load with
a constant direction that would result in a certain
contact stress at the mid-point of the rolling element
and tracking surface that are experiencing the
maximum stress.
Formula 1 gives the relation between the applied load
and the rated life of the slide rotary bush.

Calculation Example
The life of an SRE20-type NB slide rotary bush is calculated below based on the following operating conditions.
Calculation:
Basic rated load, C=647 N
Based on the above operating conditions, the life is
calculated using the following coefficient values.

Precautions Regarding Use
Shaft
Since the balls roll directly over the shaft surface in
the SRE-type slide rotary bush, the accuracy and
hardness of the shaft are important factors.
Outer Diameter : A tolerance of g6 is recommended
for smooth operation.
Hardness : A hardness of greater than 58HRC is
recommended for long life. If the hardness is less
than 58 HRC, the life is calibrated using the hardness
coefficient.
Surface Roughness : A roughness of less than 0.4Ra
is recommended.
Housing
An inner diameter tolerance of H7 is recommended.
Lubrication
Lubrication is needed (1) to prevent heat fusing and
reduce wear between the rolling elements and
between the rolling elements and the tracking
surface, (2) to reduce wear of the structural elements,
and (3) to prevent oxidation. Lubrication affects both
the performance and life of the bush. A lubrication
The use of an FLM felt seal will improve the
effectiveness of lubrication and extend the interval
between applications of a lubricant.

Installation
The felt seal should be installed as shown in Figure F-

stopper function.
F-11
method and a lubrication agent appropriate to the
operating conditions should be used. For oil
lubrication, turbine oil (V32-68) should be used. For
grease lubrication, lithium soap grease no. 2 should
be used. The replenishment interval depends on the
operating conditions.
Dust Control
Dust and other contaminants affect the bush's
lifetime and accuracy. Appropriate control methods
are thus important.
Operating Temperature Range
The SRE-type bush can be operated at temperatures
ranging from 20 to 110. In a case of operating
at a temperature outside this range, please contact
NB.
Retainer Material
The standard material of SRE Retainer is "Phosphor
Bronze". When requiring other material, please
contact NB.

NB's RK type slide rotary bush is a highly accurate rigid component providing smooth
continuous linear and rotational motion. Its structure imposes no constraints on either
motion. It is much more compact than a standard slide bush with separate rotational
bearing.
STRUCTURE AND ADVANTAGES
The RK type slide rotary bush uses a retainer similar
to that used in the SR type stroke bush. This retainer
provides the results of smooth rotational motion. The
SM type slide bush is also used providing the smooth
linear motion. Large ball elements are used enabling
the bushing to withstand high loads.
Figure F-6 Structure of RK Slide Rotary Bush
outer cylinder

F-22
1.A smooth unlimited linear and rotational
motion is obtained.
2.There is no need to machine separate
housing.
3.High accuracy is ensured for extended
period of usage.
4.Its high compatibility eliminates
replacement problems.
5.High rigidity enables it to withstand an
unbalanced load and high load capacity.
For best performance, please select tolerance of
h5 for the shaft.

Advanced Machining Technology:
NB will perform a wide variety of highly accurate
machining processes to provide custom shafting from
relatively simple machining, such as tapping and
shaft stepping to the more demanding high-speed
rotating shafts and spindles. NB can also perform
special grinding and bore machining requirements.
Excellent Wear Resistance:
High wear resistant carbon-chromium bearing steel
(SUJ2) and Martensite stainless steel (equivalent to
SUS440C) materials are most commonly used.
These materials are annealed and tempered to
achieve a reliably uniform hardened layer in both the
circumferential and axial directions. A cross-sectional
photograph illustrating the hardened layer depth of
the NB slide shaft is shown below.
The NB slide shaft is used with bearings such as a slide bush in order to obtain highly
accurate linear motion. When used in combination with a slide bush, the shaft performs as
the inner race of the bearing system. The quality and accuracy of the shaft directly affect
the performance of the slide bush. NB slide shaft is manufactured with an emphasis on
quality and accuracy to ensure stable functionality under many operating conditions.
Superior performance is guaranteed for both rotational motion and combined rotation and
linear motion.

The Geometrical moment of inertia (I) is obtained
using the following formula:
I = I = (D4-d4 For solid shaft For hollow shaft
D
)
4
64
64
I : geometrical moment of inertia (mm 4 ) D : outer dia. (mm)
d : inner dia. (mm)
The values of the geometrical moment of inertia and
C (=1/48 I) for NB slide shafts are listed in Table G-4
and G-5.
Calculation Examples:
1. Calculate the maximum deformation of a shaft with
an outer diameter of 30 mm and a span of 500 mm
when a concentrated load of 980 N is applied at the
mid-point of the shaft (neglecting the weight of the
shaft).
support-support :
From the given conditions, P is 980 N and is 500
mm
From Table G-4, C for an outer diameter of 30 mm
is 2.54 x 10 -12 (1/N mm 2 ).
Substituting these values into the corresponding
formula in Table G-3,
max = P 3 C = 0.31 mm.
fixed-fixed :
Substituting the values into the corresponding
formula given in Table G-3,
max = P 3 C = 0.08 (mm)
2. Calculate the maximum deformation of a shaft with
an outer diameter of 60 mm, an inner diameter of 32
mm, and a span of 2000 mm due to its own weight.
From Table G-5, C for an outer diameter of 60 mm
is
C = 1.73x10 -13 (1/N mm 2 )
The mass per unit length of a shaft with an outer
diameter of 60 mm and an inner diameter of 32
mm is 15.9 kg/m. Therefore, a uniformly
distributed load of 0.156 N/mm is applied.
Substituting these values into the most
appropriate formula for your application given in
Table G-3.
max = p 4 1
4
5
C = 0.27 (mm).

NB CENTER-LINED TAPPED SHAFT
G-9
A larger diameter shaft can overcome problems in maintaining precision functionality when a high or unbalanced
load is applied. The application of the center-lined tapped shaft together with the SA type support base is ideal in
such cases (see SA dimensional table on pages E-32 and E-33). The center-lined tapped shaft is standardized
to simplify selection.

NBs Slide Way NV and NVT types incorporate STUDROLLER, which has been developed
based upon a new concept. By completely eliminating slippage between the roller and
track surfaces, these new Slide Ways possess the smoothest and most accurate linear
movement in the world.
STRUCTURE AND ADVANTAGES
Non-slip STUDROLLER System
The built-in STUDROLLER system, based on the
new concept, completely eliminates slip inside
the product, covering various applications including
super-high acceleration/deceleration applications.
Compatibility with conventional types
The same dimensions and the same stroke as the
Slide Way SV type enable complete compatibility
between the two series.
Smooth movement
The optimally designed roller raceway section and
the R-retainer ensure smooth, noiseless movement.
Space and Cost Saving
Increased load capacity allows for down-sizing and
lowering costs of the component, thus enabling space
and cost saving. (comparing with conventional SV type.)
Figure H-2 STUDROLLER system
H-2
STUDROLLER system
NV type/NVT type
NBs Slide Way NV and NVT types consist of precisely ground tracking bases and Rretainers
with built-in stud-rollers. To smooth the STUDROLLER, the tracking rail is
optimally designed and the R-retainer incorporates the STUDROLLER and the precise
roller. These ideas will enable slip-free operation between the raceway surface and the
roller, resulting in motion with minimal frictional resistance.
High rigidity and high-loading capacity
Based on the new tracking base design, the contact
length of the roller and the raceway surface is
increased by 42 to 58%, and narrowing the roller
pitch increases the number of roller units to be
connected. Accordingly, the load rating is 1.4 to 2.3
times greater when compared to the conventional SV
type.

Installation Procedure
(1) Remove burrs, stains, and dust from the surface of the
track rail of tables and beds to prevent contamination
during assembly.
(2) Apply low-viscosity oil to contact surfaces, and attach the
tables to the beds (Figure H-11a).
(3) Set the reference surface shown in Figure H-6 onto the
mounting surface with the track rail assembled. Tighten
adjusting screws lightly so that almost no gap is left while
the table is set in the center (Figure H-11b).
(4) Keep table in the center, tighten track rail mounting bolts
lightly and peel the connection seal from both edges.
(5) While maintaining the conditions in (4), tighten the
adjusting screw on the R-retainer with the recommended
torque shown in Table H-2 (Figure H-11c).
(6) Move the table to one stroke end gently then, tighten the
adjusting screw on the R-retainer in the same manner as
in (5) (Figure H-11d).
(7) Move the table to the opposite stroke end and tighten the
adjusting screw in the same manner as in (5) (Figure H-11e).
(8) Tighten the mounting bolts on track rail 1, 2 and 3 with the
recommended torque shown in Table H-3 (Figure. H-11f).
(9) Set the dial indicators to the top and the side of the
reference surface of the table (Figure H-11g).
(10) Make final adjust of pre-load. Repeat steps (5) to (7) until
the indicator will show a minimum deviation.
(11) Finally, tighten the bolt on track rail with the
recommended torque. Be sure to tighten the mounting
bolts on the R retainer sequentially while moving the table
as when tightening the adjusting screws.

LUBRICATION AND DUST PREVENTION
Lubrication
The NB Slide Way is pre-lubricated using lithium
soap-based grease prior to shipment and is therefore
ready for immediate use. Make sure to lubricate with
a similar type of grease periodically according to the
operating conditions.
NB also provides grease for low-dust linear systems.
Please refer to page Eng-20 for further details.
Dust prevention
When dust and dirt enter the NB Slide Way, the
accuracy and operating life may deteriorate. It is
advisable to install an additional protective cover to
protect the unit in a harsh environment (Figure H-13).
PRECAUTIONS FOR USE
Careful handling
NV type is packaged with the track rail and R retainer
in one piece. Do not separate or disassemble these
components until installation/assembly is completed.
Dropping the NB Slide Way may cause the rolling
elements to make dents on the raceway surface. This
will prevent smooth motion and will also affect
accuracy. Make sure to handle the product with care.
Stopper
Over-stroke may cause the raceway surface of the
track rail to be damaged and the performance of the
STUDROLLER to drastically deteriorate. Be sure to
provide an external mechanical stopper and use the
product within the maximum allowable stroke.
Adjustment
Using the product without mounting surface accuracy
or before adjusting the pre-load will affect the life and

motion accuracy of the product. Make sure to install
and adjust the product with care.
Operating temperature
NV type contains resin parts. When using the
product in high-temperature environments, the
temperature must be lower than 80C.
Use as a set
The mutual accuracy in the track rails is adjusted
within a particular set. Note that the accuracy may be
affected when the track rails of different sets are
used together in combination.

The NB slide way is a non-recirculating linear motion bearing utilizing precision rollers. It is
used primarily in optical and measurement equipment where high precision movement is
required.
STRUCTURE AND ADVANTAGES
The NB slide way consists of precision ground track
bases and caged rollers. Precision rollers are used
as the rotating element. Since they do not recirculate,
there is less frictional resistance fluctuation.
Additionally, there is little or no difference between
the static and dynamic frictional resistances.
Suitable for Minute Motion:
Because the frictional resistance is extremely small
and there is little or no difference between the static
and dynamic frictional resistances, the NB slide way
is well suited for minute motion. It can follow minute
motion accurately, resulting in highly accurate linear
movement.
Low-Speed Stability:
Since the frictional resistance fluctuation is small
even under low-load conditions, stable motion is
obtained from low to high speeds.
Figure H-14 Slide Way Structure
end piece
rail
H-12
High Rigidity and High Load Capacity:
Since the rollers provide a larger contact area
compared with ball elements, there is less elastic
deformation. Additionally, since the rollers do not
recirculate, the effective number of rotating elements
is large, resulting in high rigidity and high load
capacity.
Low Noise:
The use of a roller cage prevents noise from being
generated by contact between the rotating elements,
resulting in quiet operation.
All Stainless Steel Type Available:
The anti-corrosion SVS/SVWS slide ways have all
stainless-steel components, making them ideal for
use in clean room applications.
roller cage

The SV type slide way consists of two R type roller
cages, which have precision rollers in a cross
arrangement and four rails having V-shaped raceway
surfaces. The all stainless-steel optional feature
makes it suitable for use in corrosive environments.
H-13
Accuracy:
The accuracy of a slide way is measured along its entire length, as illustrated in Figure H-16, and expressed in
terms of parallelism. It is categorized into three levels: high grade (no suffix), precision grade (P), and ultra
precision grade (UP).

The SVW type slide way consists of two R type roller
cages, two SV-type rails, and one W type rail with Vshaped
grooves on both sides. The use of a W-type
rail results in a compact design. The SVWS type is
also available with all stainless steel components.
Ultra precision grade is available for size 1-9
Rated Life:
The life of a slide way is calculated using the following equation:
Travel life: Life time:

rail - by tightening bolts to specified torque
values (Table H-6, Figure H-20a).
(3) Temporarily attach adjustable side of rail
(Figure H-20b).
(4) Remove one end-piece. Carefully insert roller
cages between rails (Figure H-20c).
(5) Re-attach end-pieces.

(6) Move table slowly to the right and left (in the
direction of the stroke) to position roller cage at the
center of the rail.
(7) Set indicators at the center and the side
(reference surface) of the table (Figure H-21d).
(8) Move table to one of the stroke ends. Lightly tighten
adjustment screw on roller cage (Figure H-21e).
(9) Move table to the other stroke end. Similarly
lightly tighten adjustment screw on roller cage (Figure
H-21f).
(10) Move table to the center and lightly tighten
center adjustment screw (Figure H-21g).
(11) Repeat steps (8) (10) until there is no
clearance around the table. When there is no
clearance, the indicator will show a minimum
fluctuation value when the table is moved to the right
and left. Exercise care not to apply an excessive preload.
(12) Make final adjustment of pre-load. Repeat steps
(8) (10) and tighten the adjustment screws to the
torque values listed in Table H-5.
(13) Fix the rail . As done for the adjustment
screws, tighten the mounting bolts by moving the
table.

Lubrication:
NB slide ways are lubricated using lithium soap
grease prior to shipment, so they can be used
immediately. Periodic application of a similar type
grease is recommended depending on the operating
conditions.
NB can also provide special grease for low dust
generation requirements. Please refer to page Eng-
20 for further details.
Dust Prevention:
Dust and dirt can affect the accuracy and life of a
slide way. A slide way used in a hostile environment
should be protected with a cover (Figure H-23).

NOTES ON OPERATION
Pre-load Adjustment:
Inaccurate pre-load adjustment may reduce the
motion accuracy, resulting in skewing and shortening
of slide way life. The pre-load should be adjusted
carefully.
Cage Slippage:
When used under high-speed, unbalanced-load, or
vibrational conditions, cage slippage may occur. The
stroke distance should be determined with sufficient
margin, and an excessive pre-load should not be
applied.
End Pieces:
End pieces are attached to each end of the slide way
to prevent removal of the cage. Do not use them as a
mechanical stopper.
Knock Pin Hole:
When using SVW type knock pin holes to attach a
slide way, the holes on the mounting surface should
be machined after attaching the W type rail. After
machining, remove the chips completely and wash as
required.
H-17
Careful Handling:
Dropping a slide way may result in scratches or dents
on the raceway surface, preventing smooth motion
and affecting accuracy. Care should be exercised in
handling.
Use as a Set:
The accuracy tolerance of a slide way is designed to
be adjusted within a particular set of components. If
components from different sets are used, accuracy
may be affected.
Allowable Load
The allowable load is a load under which the sum of
elastic deformation of the rolling element and the
raceway in the contact area subject to the maximum
contact stress is small enough to guarantee smooth
rolling movement. Where very smooth and highly
accurate liner motion is required, make sure to use
the product within the allowable load values.

STROKE AND RATED LOAD
When the stroke is changed, the new stroke distance must be determined and the rated load must be reestimated
as follows.
Stroke:
Figure H-24 Travel Distance
When the slide way moves along the tracking base,
the cage moves half the distance traveled by the slide
way in the same direction. Therefore, although the
applied load may be fixed on the table, the distance
between the load center and cage center will change.
To achieve stable accuracy, determine the stroke
distance and length of the tracking base as follows:
Rail length (L)
When the stroke is 400mm or over
S L / 1.5
When the stroke is less than 400 mm,
S L
S : stroke (mm) L : rail length (mm)

Allowable Load
The allowable load is a load under which the sum of elastic deformation of the rolling element and the raceway in
the contact area subject to the maximum contact stress is small enough to guarantee smooth rolling movement.
Where very smooth and highly accurate liner motion is required, make sure to use the product within the
allowable load values.
Rated Load:
The rated load for the slide way is obtained using the equations listed in Table H-8.

The NB slide table is a precision table equipped with a slide way. Its high-precision and lowfriction
characteristics make it well suited for use in electronics automatic-assembly
machines and optical measurement devices.
STRUCTURE AND ADVANTAGES
The NB slide table consists of a slide way
sandwiched between an accurately machined table
and a bed. Stopper is provided within the table.
High Accuracy:
The mounting surfaces of the table and bed are
precision finished to ensure high-precision linear
motion, resulting in a high-performance slide way.
Low Friction:
Its non-recirculating mechanism provides stable
motion from low to high speeds.

H-30
Compact and High Rigidity:
Being designed compactly, the NB slide table holds
the high load capacity and high-rigidity characteristics.
No Need for Adjustment:
The table is carefully assembled so that the accuracy
and pre-load are optimized, so it can be used
immediately without any further adjustment.
Ease of Mounting:
Standardized mounting holes are provided in the
table and bed. High-precision linear motion can be
achieved simply by mounting.

ACCURACY
P.H-34
P.H-40
The motion accuracy of a slide table is measured by
placing indicators at the centers of the top and side
surfaces of the table, as illustrated in Figure H-26. It
is expressed in terms of the indicator diflections when
the table is moved to the right and left under no-load
conditions.
H-31
In the SVT type slide table, the slide way is
sandwiched between an accurately machined steel
tabletop and bed. In the SVTS type, an anti-corrosion
SVS type slide way is sandwiched between an
accurately machined aluminum tabletop and bed.
The SYT/SYTS type is a thin, compact slide table.
Either tapped or counterbore type is available. The
anti-corrosion SYTS type slide table is fabricated with
all stainless steel components, making it suitable for
use in clean rooms.

Refer to page Eng. 5 for the coefficients.
NOTES ON OPERATION
Careful Handling:
Dropping a table may result in scratches or dents on
the raceway surface, preventing smooth motion and
reducing the life. Care should be exercised when
handling a table.
Dust Prevention:
Dust and foreign particles can affect the accuracy
and lifetime of a slide table. A slide table used in a
hostile environment should be protected with a cover.
Lubrication:
Lithium soap lubrication is applied prior to shipment,
so a table can be used immediately upon delivery.
Periodic application of a similar lubricant should be
necessary depending on the operating conditions.
H-32
Lh : life time (hr) S : stroke length (m)
n1 : number of strokes per minute (cpm)
Cage Slippage:
The cage can slip under high-speed motion,
unbalanced-loading, and vibrating conditions. The
motion speed of a slide table should be kept under 30
m/min.
Adjustment/Installation Screws:
The NB slide table is adjusted to achieve optimum
accuracy and pre-load. The adjustment screw and
tracking-bed installation screws should not be
changed.
Allowable Load
The allowable load is a load under which the sum of
elastic deformations of the rolling element and the
raceways in the contact area subject to the maximum
contact stress is small enough to guarantee smooth
rolling movement. Where very smooth and highly
accurate liner motion is required, make sure to use
the product within the allowable load values.

SPECIAL REQUIREMENTS

The NB miniature slide table SYBS type is a limited stroke slide with the most compact
envelope dimensions, featuring two ball raceway grooves. The SYBS type utilizes ball as
the rolling elements. The ultra compact design contributes greatly to the creation of
smaller and lighter industrial machinery and equipment of all types.
Structure and Advantages
NB's miniature slide table incorporates a unique
integrated ball cage between the table and bed. All
components have been produced with high precision
machining technologies.
Ultra Compact Design
The table height of the SYBS type is 3.2 ~ 4.5mm
and the width is 6 ~ 12mm. This compact envelope
when compared with conventional slide tables helps
to realize the miniaturization of machinery and
equipment.
Low Friction - Low Noise
Since the rolling ball elements do not re-circulate, the
frictional resistance will not vary significantly resulting
in smooth operation reliable high precision.
Figure H-27 Structure of SYBS Type Slide Table
stopper
ball cage
table
H-48
Additionally, the caged balls greatly reduce the
contact noise of the rolling elements bringing about a
low-noise operation.
High Accuracy
The ball raceway grooves of the bed and table are
processed through simultaneous precision machining
resulting in minimal processing errors, and bringing
about extremely smooth, precision linear movement.
Stainless Steel Structure
The SYBS type slide table is constructed from only
stainless steel materials. This allows for use in
corrosive or high temperature applications. The
SYBS is a perfect component for vacuum or clean
room type environments.

Mounting
Shape of Mounting Surface
In most general installations, the Miniature Slide Table is mounted by pushing the reference planes of the bed
and table against a shoulder that is set up on the mounting surface. Machined escape grooves should be used in
the corners of the shoulder (as illustrated in Figure H-30) so that the corners will not interfere with the reference
corners of the bed and/or table. Table H-11 lists the recommended shoulder heights of the mounting reference
planes for the opposing sides.
When installing the Miniature Slide Table without providing machined escape grooves, the corner radius may be
realigned as illustrated in Figure H-31. Table H-12 list the values of the corner radius of the mounting surfaces.

Stopper
On both ends of the SYBS Miniature Slide Table bed
section, stopper screws have been attached to
prevent the ball cage from escaping. Please note
that the screws are designed only to prevent the ball
cage from escaping and are not intended for the use
as a mechanical stopper. The ball cage may become
deformed on contact with the stopper and this will
result in a negative affect of the accuracy and rated
life of the table.
Lubrication
NB's Miniature Slide Table SYBS Type is supplied
with an initial application of lithium soap grease and
therefore is ready for immediate use. Periodic
application of a similar lubricant should be necessary
depending on the operating conditions. For use in
clean rooms or vacuum environments, miniature slide
tables without grease or with customer specified
grease are available. NB also provides low dust
generation lubricant. Please refer to page Eng-20 for
further details.
H-51
Precautions for Use
Mounting Example and Mounting Screws
All taps used for mounting the SYBS are fully through-hole. Mount the SYBS type as illustrated in Figure H-33
only after considering the size of mounting screw, the maximum penetration depth, and the height of the bed.
Make certain that the mounting screws do not interfere with the ball cage; otherwise, the accuracy and travel life
of this table will be affected adversely. Special bolts are designed for SYBS type and are available from NB.
Please refer to Table H-14 for dimensions of these special mounting screws.

Table H-14 Mounting Screws (Material: Stainless Steel) Unit: mm Figure H-34 Mounting Screw
D
H L
Ball Cage Displacement
When a miniature slide table is operated at high
speeds; when offset loads or vibrations are present,
the ball cage may deviate from the nomal position. In
general operating conditions this is normal and it is
recommended that the table be cycled to perform
maximum full stroke travel several times during
operation. This will allow the ball cage to be returned
to its normal central position.
Pre-Load
The SYBS Minearture Slide Table is prepared with
only a slight positive-clearance.
Allowable Load
The allowable load is a load under which the sum of
elastic deformation of the rolling element and the
raceway in the contact area subject to the maximum
contact stress is small enough to guarantee smooth
rolling movement. Where very smooth and highly
accurate liner motion is required, make sure to use
the product within the allowable load values.

Nippon Bearing's Gonio Way family has adopted the RVF type with a flat installation
surface for easy processing of tables and beds.
NB Gonio Way (RVF type) is a low-friction, non-recirculating curved motion bearing utilizing
precision cross-rollers. The RVF type is ideal for changing the gradient or for obtaining an
accurate gradient angle without changing the center of rotation. This component is used
mainly in optical equipment and measuring devices where high precision is required.
Structure and Advantages
Flat Installation Surface
The flat installation surfaces of the RVF type do not
require complicated machining of tables and beds
when installing the product. As a result, machining
costs can be reduced greatly.
Same Rotation Center
The curved V-grooves, which are finished with a
precise grinding process, provide an accurate center
of rotation.
Furthermore, the products are composed to provide
identical rotation centers when products of each size
are installed to two axes. (Refer to Table H-17.)
H-54
RVF type
The NB Gonio Way RVF type consists of curved tracking bases with precisely ground V-grooves and flat
installation surfaces, as well as a curved roller cage in which cross rollers are fitted. Precision rollers are
employed as the rolling elements. Since the rolling elements do not recirculate, the frictional resistance will not
vary significantly, providing curved movement with extremely low frictional resistance.
Figure H-35 Structure of RVF Type Gonio Way
A-curved tracking base
End piece
Installation surface
Low Frictional Resistance and Minute
Motion
The precision grinding work and curved roller cage
allow for extremely low frictional resistance. The
negligible difference between starting and dynamic
frictions allows the RVF type to follow minute
movements accurately, realizing curved movement of
high accuracy.
Low Noise
Since NB Gonio Way employs a non-recirculating
design, noise will not be generated at the circulating
area. In addition, the curved roller cage realizes quiet
operation without contact noise between the rolling
elements.

ACCURACY
The accuracies of the Gonio Way RVF type are
represented by mutual dimensional errors of four
units, which are measured along the overall length
using the procedure as shown in Figure H-36.

INSTALLATION
Figure H-38. Installation Example
Installation Procedure
Setting the curved tracking bases temporarily
(1) Remove burrs, stains, and dust from the
installation surface of the curved tracking bases
of tables and beds. Foreign objects must be kept
out of the assembly work as well.
(2) Apply oil of low viscosity to contact surfaces,
check the reference edges of an A-curved
tracking base and bed, and then tighten the bolts
temporarily. (Figure H-39)
(3) Align the reference edges (NB mark side) of a Bcurved
tracking base and an A-curved tracking
base to the same orientation. Then, insert the
curved roller cage between the curved tracking
bases at the center area. Make sure that the
curved roller cage will not interfere with the
curved raceway grooves of the curved roller
tracking bases. (Figure H-39b)
(4) Check the reference edge of the table, set the
table over the B-curved tracking base, and then
secure the table temporarily. (Figure H-39c)
Setting four curved tracking bases in parallel position
(5) Move the table to the maximum stroke ends of
both sides and adjust the setting so that the
curved roller cage is positioned at the center of
the curved tracking base.
(6) Move the table to the center position and tighten
the adjustment screw with slightly strong torque *
by using a torque wrench. (Figure H-39d)
* "Slightly strong torque" here means slightly stronger than the torque at
which the oscillation of the test indicator is stabilized at the minimum
value when the table is moved right and left, or when pressure is
applied to the rolling direction while the test indicator is attached to the
side face (reference side) of the table. (Figure H-40i)
(7) Move the table to the maximum stroke end of one
side and tighten the regulating screw on the
curved roller cage with the same torque as in
step (6). (Figure H-39e)

Securing the curved tracking bases
(9) Mount an edge reference plate between the
reference edge of the A-curved tracking base
and end piece, press it against the reference
edge of the bed, and then tighten only the
mounting bolt in the middle. (Figure H-40g)
(10)Repeat the procedure above to mount an edge
reference plate between the reference edge of
the B-curved tracking base and the end piece.
Press it against the reference edge of the bed,
and then tighten only the mounting bolt in the
middle. (Figure H-40h) In order to maintain
parallelism of curved tracking bases, do not cycle
the table during this process and make sure that
there is no clearance between the edge of the
table and the edge reference plate.
(11)Secure the rest of the mounting bolts on the
curved roller cage one by one while moving the
table as instructed in steps (7) and (8).
Adjusting the preload
(12)Move the table to the right and left with the test
indicator attached to the side face of the table
(reference side). Or, apply pressure in the rolling
direction and confirm that the oscillation of the
attached indicator is stabilized at the minimum
level. (Figure H-40i)
(13)Return the mounting bolt on the B-curved
tracking base at the adjustment screw side to the
temporary setting.
(14)Return the table to the center position, slightly
loosen the adjustment screw in the middle, and
then gradually loosen the adjustment screws on
the curved roller cage while moving the table as
instructed in steps (7) and (8). Make sure not to
reduce the preload too much.
(15)Finally, secure the B-curved tracking base at the
adjustment screw side, which has been installed
temporarily. Secure the mounting bolts on the
curved roller cage one by one while moving the
table as instructed above.

PRECAUTIONS FOR USE
Lubrication:
NB gonio ways are lubricated using lithium soap
grease prior to shipment, so they can be used
immediately. Periodic application of a similar type
grease is recommended depending on the operating
conditions.
NB also provides low dust generation grease for the
linear system. Please refer to page Eng-20 for further
details.
Dust Prevention:
If a foreign matter, such as dust and dirt, enters the
inside of the NB gonio way, it may deteriorate the
accuracy and life of the system. A gonio way used in
a hostile environment should be protected with a
cover.
Use Environment:
The recommended operating temperature range of
the NB gonio way is -20 to 110.
Adjustment:
Inaccurate adjustment of the accuracy on the
mounting surface or pre-load may reduce the motion
accuracy, resulting in skewing and shortening of
gonio way life. The adjustment should be carried out
carefully.
Cage Slippage:
When used under high-speed, unbalanced-load, or
vibrational conditions, cage slippage may occur. The
stroke distance should be determined with sufficient
margin, and an excessive pre-load should not be
applied.
H-59
End Pieces:
End pieces are attached to each end of the NB gonio
way to prevent removal of the curved roller cage. Do
not use as a mechanical stopper.
Careful Handling:
Dropping a NB gonio way may result in scratches or
dents on the raceway surface, preventing smooth
motion and affecting accuracy. Care should be
exercised in handling.
Use as a Set:
The accuracy tolerance of a gonio way is designed to
be adjusted within a particular set of components. If
components from different sets are used, accuracy
may be affected.
Allowable Load:
The allowable load is a load under which the sum of
elastic deformation of the rolling element and the
raceway in the contact area subject to the maximum
contact stress is small enough to guarantee smooth
rolling movement. Where very smooth and highly
accurate liner motion is required, make sure to use
the product within the allowable load values.

MINIATURE SLIDE
ACTUATOR SLIDE SCREW

Suitable for Minute Motion:
The frictional resistance is extremely small and there
is little or no difference between the static and
dynamic frictional resistance. The NB Gonio slide
way is well suited for minute motion. It can follow
minute motion accurately, resulting in highly accurate
curved motion.
High Rigidity and High Load Capacity:
The rollers provide a larger contact area than ball
elements and there is less elastic deformation.
Additionally, since the rollers do not recirculate, the
effective number of rotating elements is larger,
resulting in high rigidity and high load capacity.
H-62
RV type
The NB Gonio way is a curved SV type slide way. It is a curved motion bearing utilizing lowfriction,
non-recirculating, precision cross-rollers. It is used when there is a need to change
the gradient or obtain an accurate gradient angle without changing the center of rotation in
high-precision optical and measurement equipment.
STRUCTURE AND ADVANTAGES
The NB Gonio way consists of hardened curved tracking bases with precisely machined V-grooves and a curved
roller cage with cross-rollers. High-precision rollers are used as the rotating elements. Since the rotational
elements do not recirculate, there is less friction fluctuation, resulting in a low-frictional curved motion.
Figure H-42 Structure of RV Type Gonio Way
end piece
Ease of Assembly and Installation:
The rollers are retained inside a curved roller cage,
allowing assembly, installation, and the handling of
components simplified. A set of components consists
of 4 curved tracking bases, 2 curved roller cages, and
8 end pieces. It can be assembled immediately.
Low Noise:
The use of a roller cage prevents noise from being
generated by contact between the rotating elements,
resulting in quiet operation.

Accuracy of Mounting Surfaces:
The accuracy of the mounting should be maintained
as needed for the operation. The accuracy of
surfaces 1, 2, 3, and 4 (Figure H-45) directly affect
the motion accuracy. They should be sufficient for the
intended operation.
Procedure:
(1) Remove burrs, dirt, dust, etc. from the table and
the installation surfaces of the bed.
(2) Apply a low viscosity oil to contact surfaces. Fix
the rail and by tightening bolts to specified
torque values (Table H-19, Figure H-46a).
(3) Temporarily attach the rail on curved tracking
base to the adjustment side (Figure H-46b).
(4) Remove the end pieces on one side of the rails
and insert roller cages to the center (Figure H-
46c).
(5) Re-attach end-pieces.
(6) Move table to the right and left (in the direction of
the stroke) to position roller cages at the center of
the curved rails.
(7) Set an indicator at the side of the table on the
reference surface (Figure H-46d).
(8) Move table to one of the stroke ends and tighten
the adjustment screws slightly. Figure H-47e).

(11) Repeat steps (8) (10) until there is no
clearance around the table. If there is no
clearance, the indicator will show a minimum
fluctuation value when the table is moved to the
right and left. Exercise care so as not to apply
an excessive amount of pre-load.
(12) Repeat steps (8) (10) and tighten the
adjustment screws uniformly.
(13) Fix the rail . Tighten the roller cage bolts
sequentially by moving the table in the same
manner as for tightening the adjustment screws.

NOTES ON INSTALLATION
Lubrication:
NB Gonio slide ways are pre-lubricated using lithium
soap grease prior to shipment, so they can be used
immediately. Periodic application of a similar type
grease is recommended depending on the operating
conditions.
Dust Prevention:
Dust and foreign particles can affect the accuracy
and life of a Gonio slide way. A table used in a hostile
environment should be protected with a cover.
Operating Temperature:
The operating temperature should be kept between -
20 o C and 110 o C.
Pre-load Adjustment:
Inaccurate pre-load adjustment will reduce the
motion accuracy, resulting in skewing and shortening
life. Careful adjustment is a requirement.
Cage Slippage:
When used under high speeds, or unbalanced loads,
or when vibration condition are present, the roller
cage slippage may occur. The rotation range should
be determined with a sufficient margin, and an
excessive pre-load should not be applied.

End Pieces:
End pieces are attached to each end of the rail to
prevent removal of the cage. Do not use them as a
mechanical stopper.
Careful Handling:
Dropping a Gonio slide way may result in scratches
or dents on the raceway surfaces, preventing smooth
motion and affecting accuracy. Care should be
exercised in handling.
Use as a Set:
The accuracy tolerance of a Gonio slide way is
designed to be adjusted within a particular set of
components. If components from different sets are
used, the accuracy may be affected.

NB's BG type is a compact single axis actuator which integrates a slide guide and precision
ball screw.
BG type offers compact dimensions and outperforms conventional positioning tables. This
is made possible by a unique "U" shaped guide rail and slide block which provides multiple
functions of a guide block and a ball screw nut combined into a single unit. The "U" shaped
guide rail design offers a high rigid structure resistant to bending. This structural feature
allows for integrated framework of machinery or equipment and may be one-end supported.
Additionally, the slide block contains 4 ball circuits which delivers high load capacity, high
accuracy and high rigidity.

ADVANTAGES
Adjustment Free:
The integration of the slide guide and precision ball
screw eliminates complex precision adjustment and
reduces installation time dramatically.
High Rigidity:
"U" shaped guide rail provides very high rigidity
despite its compact configuration and can be used for
one-end supported application.(Reference Page I-9)
High Accuracy:
BG type contains four ball circuits and four-point
contact ball grooves which contributes to its high
rigidity. The combination of precision ground guide
rail, slide block and precision ball screw provides high
positioning accuracy.
Space Saving:
In comparison to conventional positioning tables, the
BG type allows for compact designs and dramatic
space saving. The "U" shaped guide rail and
integrated slide block / precision ball screw nut make
this possible.

Positioning Repeatability:
Establish an arbitrary point. From one end, position
the inner block at this point and measure the stop
position. Repeat the positioning and measurement
process 7 times. Repeat the same process with
respect to the established set point at the midpoint
and near both ends of travel. Take the maximum
measurement and divide the maximum difference by
2 and indicate it with either a positive or negative sign
as the test results.
Positioning Repeatability=
1/2{(Maximum value of n)-(Minimum value of n)}
Positioning Accuracy:
Positioning is performed in only one direction and the
resulting position is set as the reference measurement
point. Calculate the difference between the length of
actual travel and the commanded travel length.
Continuing in the same direction (without returning to
the start point) repeat this process randomly several
times until reaching limit of full stroke. Express the
accuracy by the absolute maximum difference.
Positioning accuracy = (n)max
Running Parallelism:
Making sure that the surface plate is absolutely flat.
Indicator placed on the center of block, run the block
over the entire length of travel and use the maximum
difference in readings as the test results.
Backlash:
Use the feed screw to move the block a little. Take
the test indicator reading and make it the reference
point. While in this position, load the block in the
same direction without using the feed screw.
Release the load and read the return. Calculate the
difference between the reference point. Repeat the
same process at the midpoint and near both ends.
Use the maximum difference as the test result.
Backlash = ()max

RATED LIFE
To obtain the rated life of the BG type, calculate the
rated life of the guide section, and ball screw section
or support section. Use the minimum value as the
rated life of the BG type. Use the following equation
for calculating the rated life.
A. Life of Guide portion
Use the following formula for calculating the rated life
of Guide portion.
3
LG= 50(1) fc C
fw PT
LG : Rated life (km)fc : contact coefficient (see Table I-8)
fw : load coefficient (see Table I-9)C : basic dynamic load rating (N)
PT : calculated load applied to one block (N)
A.1. Calculation of PT
Before calculating the rated life using the equation
(1), the calculated load applied to one block (PT)
needs to be obtained in consideration of the moment
load, etc. that will be actually applied.
For rapidly-accelerating or short stroke motion, PT
needs to be calculated with acceleration taken into
consideration. The calculation of this acceleration will
be carried out for the mass applied to BG.
Obtain the calculated load during uniform motion,
accelerating, and decelerating, and use the average
value of the three as PT.
For the calculation of PT, select an appropriate
equation depending on the installation conditions of
the guide.
It is also possible to calculate PT without including the
effect of acceleration by using the equation PT = PTc
(see the equations (2), (5), and (8)). In this case,
however, the obtained value is an approximate one,
so a selection with sufficient margin is recommended.

LUBRICATION
BG type contains a lithium-soap based grease.
Apply similar grade of grease for the lubrication as
required depending on your terms of operation.
Use grease fitting to lubricate the guide block. For
ball screw apply grease directly to surface of screw
shaft.
Unless otherwise instructed, a grease fitting is
located as shown in Figure I-15.
The greases can be changed to a high-function
type by adding a special grease option code at the
end of the part number. Please refer to Table I-12
for the type of the greases. Also refer to page Eng-
20 for further detail of greases.

Resin parts are assembled in BG type. The recommended ambient working temperature is 80 or lower.
Apply 55 or lower for photo micro sensor option type.
Handle as a precision component to avoid excessive vibration or shock. Rough handling will affect the smooth
traveling and may reduce the precision performance and/or life of the BG type.
DO NOT DISASSEMBLE. The accuracy of BG type is adjusted by the factory when it is assembled.
Allow for extra stroke distance. If the guide block repeatedly collides with damper, it may cause damage.
Depending upon the operating environment, dust and debris may contaminate BG type and disrupt the ideal
ball circulation and operating performance.

POSITIONING PIN HOLE
For the BG type, positioning pin holes can be provided on the slide block or the sub-table by adding the option
code PS or PW at the end of the part number. When two blocks are used in the BG, the both blocks will
be processed.
It is useful when exacting reassembly positioning is required.
When the code PS is added, the drilling is processed only on the mounting surface. On the other hand, when
the code PW is specified for a BG with a cover, straight pins will be used at the connecting area of the slide
block and the sub table (although the position is the same as the for PS).
Note that only hole drilling is processed to the mounting surface and that no straight pin will be attached.

The NB slide screw consists of two aluminum blocks,
each with three radial bearings with a fixed angle
between them. A round shaft is inserted between the
two blocks, and its rotation produces linear motion
determined by the contact angle between the shaft
and bearings. For variable loads, the thrust is
adjusted by turning the spring loaded hexagonal
bolts.
Linear Motion on a Round-shaft:
The NB Slide Screw is suitable for long-stroke
applications using a standard linear shaft.
The NB slide screw converts rotational motion into linear motion by utilizing the friction
between radial ball bearings and a shaft. This simple mechanism eases maintenance and
installation cost. The slide screw is most commonly used as transport devices in many
types of machines, and is not intended for accurate positioning requirements.
STRUCTURE AND ADVANTAGES
Figure J-1 Structure of NB Slide Screw
ball bearings
shaft
J-2
High Machine Efficiency:
The slide screw utilizes the rotational motion of the
bearings and shaft to achieve machine efficiency as
high as 90%.
No Lubrication Required:
The bearings are pre-lubricated with grease prior to
shipment, so there is no need to apply lubrication
other than to the drive shaft to prevent corrosion.
Excessive Load Prevention Mechanism:
When an excessive load is applied, the screw will
stop due to slippage, thereby preventing accidents.
thrust adjustment bolts
blocks

SELECTION METHOD
Required Thrust:
Tightening of the bolts creates a thrust force that
pushes the bearings against the shaft. This results in
a constant force being applied to the bearings
regardless of the load. The thrust should not be
greater than required force in the application.
F1= gW (1)
F1 : frictional resistance (N) : friction coefficient W : mass of work (kg)
g : gravitational acceleration (9.8 m/sec 2 )
A sufficient safety margin should be achieved at =
0.01. Also, the inertia at starting and stopping should
be taken into consideration.
F2= W
dv
(2)
dt
F2 : inertia (N) W : mass of work (kg) dv/dt : acceleration (9.8m/sec 2 )
Therefore, the required thrust is its maximum limit at
starting point due to the combination of frictional
resistance and inertia.
F = F1+F2 (3)
F : thrust (N) F1 : frictional resistance (N) F2 : inertia (N)
Torque:
After deciding the thrust required, decide the driving
torque corresponding to that thrust. The torque is
calculated as follows:
Fa
T= (4)
2
T : driving torque (N.cm) Fa : axial load (N)
: lead (cm) : efficiency (0.9) Fa=Fo
J-3
Life:
The rated life is expressed in terms of the number of
revolutions of the drive shaft: Equation (5). The
corresponding total distance traveled and life time are
given in Equations (6) and (7) respectively.

Allowable Rotational Speed:
When the rotational speed is increased and
approaches the shaft resonant frequency, the shaft
is disabled from further operation. This speed is
called the critical speed and can be obtained by the
following equation. In order to leave a sufficient safety
margin, the maximum operating speed should be set
at about 80% of the calculated value.

If modulus of direct elasticity is 2.06 x 10 5 N/mm 2 and

Sample Calculation:
1. Selecting a slide screw that satisfies the following
conditions:
Support method: fixed-supported
Support distance: 1,500 mm
External force: 98 N
Table mass: 50 kg
Stroke distance: 1,200 mm
Friction coefficient: 0.01
Maximum speed of movement: 12 m/min
Strokes per minute: 4
Determination of required thrust:
F = 98+(0.01509.8)=102.9N
Therefore, based on the maximum thrust required, at
least SS10 is required in size.
Allowable rotational speed:
From Equation (9)
According to the conditions, the critical speed Nc is.
Nc = 12.2 D10 6 2

INSTALLATION
1. Clean dust from drive shaft.
2. Place shaft between upper and lower blocks.
Lightly tighten hexagonal bolts until the clearance
between the shaft and the bearings diminishes.
3. Temporarily attach the slide screw to the table.
4. Adjust the parallelism between the slide screw and
the linear motion guides by manually moving the
table forward and backward. Fix the shaft accurately
after the required parallelism is achieved.
NOTES ON OPERATION
Use of a heat-treated ground shaft such as NB's
slide shaft to prevent wear and obtain smooth motion
is recommended.
Since the slide screw utilizes the friction between
the bearings and the shaft, the lead varies due to the
effect of load variation, movement direction, and shaft
conditions. Highly accurate positioning can be
obtained by attaching a linear scale to the aluminum
blocks.
If the slide screw and shaft are not parallel, an
unbalanced load will be applied to the slide screw.
Exercise care in controlling the parallelism.
SPECIAL REQUIREMENTS
J-6
5. Tighten the bolts evenly while appling a thrust
force untill slippage disappears. Care should be
required to avoid excessive tightning which results in
shortening the rated life.
The slide screw slips on the shaft if an excessive
load is applied, in order to prevent damage. However,
frequent slippage should be avoided not to shorten
the travel life.
Please transfer the radial load to linear motion
guides since the radial load on the slide screw
shortens the rated life.
NB can fabricate slide screws to meet special requirements, including screws with a special lead or a even
reverse lead. Contact NB for further information.
