Selection Flow Chart 

When an external guide is used, the selection confirmation of the guide capacity should follow the selection procedure 

of the external guide. 

The MY3 series allow direct load application within the allowable range for the built-in guide. The payload in this case 

will vary depending on the driving speed and the mounting orientation of the cylinder. Please refer to the flow below and 

confirm the selection. (For more detailed description of the selection flow, please refer to the instruction manual.)

Calculation of Guide Load Factor 

1. Maximum load mass (1), static moment (2), and dynamic moment (3) (at the time of impact with stopper) must be examined for the selection calculations. 

∗ To evaluate, use υa (average speed) for (1) and (2), and υ (impact speed υ = 1.4υa) for (3). Calculate m max for (1) from the maximum allowable load graph (m1, m2, m3 ) 

and Mmax for (2) and (3) from the maximum allowable moment graph (M1, M2, M3).

Note 1) Moment caused by the load, etc., with cylinder in resting condition. 

Note 2) Moment caused by the impact load equivalent at the stroke end (at the time of impact with stopper). 

Note 3) Depending on the shape of the work piece, multiple moments may occur. When this happens, the sum of the load factors (Σα) is the total of all such moments. 

Note 2) 

2. Reference formulas [Dynamic moment at impact] 

Use the following formulas to calculate dynamic moment when taking stopper impact into consideration. 

m : Load mass (kg) 

υ : Impact speed (mm/s) 

F : Load (N) 

FE : Load equivalent to impact (at impact with stopper) (N) 

υa : Average speed (mm/s) 

M : Static moment (N • m)

The above calculation is within the allowable value, and therefore the selected model can be used. 

Select a shock absorber separately. 

In an actual calculation, when the sum of guide load factors Σα in the formula above is more than 1, consider 

decreasing the speed, increasing the bore size, or changing the product series.

Rubber Bumper Displacement (Additional Stroke due to Pressure on Each Side) 

The stop position of the built-in rubber bumper of the MY3A series varies depending on the operating pressure. For alignement at 

the stroke end, find the guideline for the stroke end position in operation as follows. Find the incremental displacement at the operating 

pressure in the graph and add it to the stroke end position at no pressurization. If positioning accuracy is required for the 

stop position at the stroke end, consider installing an external positioning mechanism or switching to the air cushion type (MY3B).

External Shock Absorber Selection 

When the positioning of the stop position is necessary or the absorption capacity of the built-in cushion is not 

sufficient, refer to the selection procedure below and consider the installation of an external shock absorber.

An external shock absorber can be used within the above piston 

speed range. In conjunction with the absorption capacity 

selection, however, also confirm the conditions which make 

the shock absorber collision impact force to stay within the allowable 

range in the graph. 

Use of an external shock absorber with conditions exceeding 

the allowable range may damage the cylinder. 

To confirm the collision impact force of the shock absorber, 

first find the impact force or acceleration under the 

operating conditions using the selection information or 

selection software provided by the manufacturer and 

then, refer to the graph. 

(The selection should allow a sufficient margin because the 

value calculated by the selection software involves an error 

with reference to the actual value.)

When the RB series is used, operate at a piston speed that will not exceed 

the absorption capacity of the air cushion and stroke adjusting unit. 

Note) The tolerance of the MY3A is a value with no pressurization. When a rubber bumper 

is used, the stroke of the MY3A varies according to the operating pressure. 

To find the stroke length tolerance at each operating pressure, double the additional 

stroke due to pressure on each side (page 1133) and add it.

For long stroke operation, the cylinder tube 

may be deflected depending on its own 

mass and the load mass. In such a case, 

use a side support in the middle section. 

The spacing (l) of the support must be no 

more than the values shown in the graph on 

the right.

Caution 

q If the cylinder mounting surfaces are not 

measured accurately, using a side support 

may cause poor operation. Therefore, be 

sure to level the cylinder tube when 

mounting. Also, for long stroke operation 

involving vibration and impact, use of a 

side support is recommended even if the 

spacing value is within the allowable limits 

shown in the graph. 

w Support brackets are not for mounting; use 

them solely for providing support.

Guide for Using Side Support 

For long stroke operation, the cylinder tube 

may be deflected depending on its own 

mass and the load mass. In such a case, 

use a side support in the middle section. 

The spacing (l) of the support must be no 

more than the values shown in the graph on 

the right.

Caution 

q If the cylinder mounting surfaces are not 

measured accurately, using a side support 

may cause poor operation. Therefore, be 

sure to level the cylinder tube when 

mounting. Also, for long stroke operation 

involving vibration and impact, use of a 

side support is recommended even if the 

spacing value is within the allowable limits 

shown in the graph. 

w Support brackets are not for mounting; use 

them solely for providing support.

Series MY3 

Specific Product Precautions 1 

Be sure to read before handling. 

Refer to front matters 54 and 55 for Safety Instructions and pages 3 to 11 for Actuator 

and Auto Switch Precautions. 

Caution on Design 

Warning 

1. A deceleration circuit or shock absorber 

may be required. 

When a driven object is operated at high speed or the load is 

heavy, a cylinder’s cushion will not be sufficient to absorb the 

impact. Install a deceleration circuit to reduce the speed before 

cushioning, or install an external shock absorber to relieve 

the impact. In cases such as these, the rigidity of the machinery 

should also be examined. 

∗ The external shock absorber should conform to the 

conditions on page 1135. Use caution because the use 

of a shock absorber falling short of the recommended 

conditions may damage the cylinder. 

Caution 

1. Due to structural differences, fluctuations in 

the operating speed of mechanically jointed 

rodless cylinders may be larger than rod 

type air cylinders. 

Please consult with us if you require a precise, constant, 

speed in your application. 

Selection 

Caution 

1. Provide intermediate supports for long 

stroke cylinders. 

Provide intermediate supports for cylinders with long strokes 

to prevent rod damage due to sagging of the rod, deflection of 

the tube, vibration and external loads. 

For detailed information, please refer to "Guide for Using Side 

Support" on pages 1143 and 1155. 

2. For intermediate stops, use a dual-side pressure 

control circuit. 

Since the mechanically jointed rodless cylinders have a unique 

seal structure, slight external leakage may occur. Controlling 

intermediate stops with a 3 position valve cannot hold the 

stopping position of the slide table (slider). The speed at the 

restarting state also may not be controllable. Use the dual-side 

pressure control circuit with a PAB-connected 3 position valve 

for intermediate stops. 

3. Constant speed 

Since the mechanically jointed rodless cylinders have a unique 

seal structure, a slight speed change may occur. For applications 

that require constant speed, select an applicable equipment 

for the level of demand. 

4. Load factor of 0.5 or less 

When the load factor is high against the cylinder output, it may 

adversely affect the cylinder (condensation, etc.) and cause 

malfunctions. Select a cylinder to make the load factor less 

than 0.5. (Mainly when using an external guide) 

5. Cautions on less frequent operation 

When the cylinder is used extremely infrequently, operation 

may be interrupted in order for anchoring and a change lubrication 

to be performed or service life may be reduced. 

Selection 

Caution 

6. Consider uncalculated loads such as piping, 

cableveyor, etc., when selecting a load moment 

Calculation does not include the external acting force of piping, 

cableveyor, etc. Select load factors taking into account the 

external acting force of piping, cableveyor, etc. 

7. Accuracy 

The mechanical jointed rodless cylinder does not guarantee 

traveling parallelism. When accuracy in traveling parallelism 

and a middle position of stroke is required, please consult with 

SMC. 

Mounting 

Caution 

1. Do not apply strong impacts or excessive 

moment to the slide table (slider). 

Do not apply strong impact or excessive moment in mounting 

the work piece because the slide table (slider) is supported by 

resin bearings. 

2. When connecting to a load which has an external 

guide mechanism, use a discrepancy 

absorption mechanism. 

A mechanically jointed rodless cylinder can be used with a direct 

load within the allowable range for each guide type, however, 

careful alignment is required when connecting to a load 

having an external guide mechanism. Mount the external 

guide mounting brackets and floating brackets in a place 

where the required degree of freedom for the floating Y and Z 

axes can be secured. 

The thrust transmission area of the floating bracket must be 

fixed so that it does not partially contact the body. 

∗ Refer to the Coordinates and Moment in Model Selection on page 1144 

for the details of floating Y and Z axes. 

3. At each end of the cylinder, secure a mounting 

surface with a 5 mm or longer area that 

contacts the lower side of the cylinder. 

5 mm or more 

Side support 

5 mm or more 

4. If the cylinder is mounted on the ceiling or 

wall under the condition where high load 

factors or impacts are expected, use side 

supports, in addition to the fixing bolts on 

the head cover, to support both ends of the 

cylinder tube.

Mounting 

5. Do not mount cylinders as they are twisted. 

When mounting, be sure for a cylinder tube not to be twisted. 

The flatness of the mounting surface is not appropriate, the 

cylinder tube is twisted, which may cause air leakage due to 

the detachment of a seal belt, damage a dust seal band, and 

cause malfunctions. 

6. Do not mount a slide table on the fixed equipment 

surface. 

It may cause damage or

malfunctions since an 

excessive load is applied 

to the bearing. 

Slide table 

7. Consult with SMC 

when mounting in a Mounting with a slide table (slider) 

cantilevered way. 

Since the cylinder body 

deflects, it may cause 

malfunctions. Please 

consult with SMC when 

using it this way. 

8. Do not generate 

negative pressure 

in the cylinder tube. 

Head cover 

Operating Environment 

Slide table 

Cylinder tube 

Mounting in a cantilevered way 

Take precautions under operating conditions in which negative 

pressure is generated inside the cylinder by external forces or 

inertial forces. Air leakage may occur due to separation of the 

seal belt. Do not generate negative pressure in the cylinder by 

forcibly moving it with an external force during the trial operation 

or dropping it with self-weight under the non-pressure state, etc. 

When the negative pressure is generated, slowly move the cylinder 

by hand and move the stroke back and forth. After doing 

so, if air leakage still occurs, please consult with SMC. 

1. Avoid use in environments where a cylinder 

will come in contact with coolants, cutting oil, 

droplet of water, adhesive matter, or dust, etc. 

Also avoid operation with compressed air that 

contains drainage or foreign matter, etc. 

• Foreign matter or liquids on the cylinder's interior or exterior 

can wash out the lubricating grease, which can lead to deterioration 

and damage of dust seal band and seal materials, 

causing a danger of malfunction. 

When operating in locations with exposure to water and oil 

drops, or in dusty locations, provide protection such as a 

cover to prevent direct contact with the cylinder, or mount so 

that the dust seal band surface faces downward, and operate 

with clean compressed air. 

2. Carry out cleaning and grease application 

suitable for the operating environment. 

Carry out cleaning regularly when using in an operating environment 

in which the product is likely to get dirty. 

After cleaning, be sure to apply grease to the top side of the 

cylinder tube and the rotating part of the dust seal band. Apply 

grease to these parts regularly even if not after cleaning. 

Please consult with SMC for the cleaning of the slide table 

(slider) interior and grease application.

Handling 

1. Do not unnecessarily alter the guide adjustment 

setting. 

• The adjustment of the guide is preset and does not require 

readjustment under normal operating conditions. Therefore, 

do not unnecessarily alter the guide adjustment setting. 

However, series other than the MY3M series can be readjusted 

and their bearings can be replaced. To perform these 

operations, refer to the bearing replacement procedure given 

in the instruction manual. 

2. Do not use the cylinder when the pressure 

inside the cylinder will turn to negative pressure. 

In operating conditions where negative pressure is generated 

inside a cylinder — by the external force or inertial force, etc. 

— be careful as the seal may distort or detach, resulting in air 

leakage. 

3. Use caution not to have your hands caught 

in the unit. 

When using a cylinder with stroke adjusting unit, the space 

between the slide table (slider) and the stroke adjusting unit is 

very narrow. Care should be taken to avoid the danger of 

hands being caught in this small space. Install a protective 

cover to prevent the risk of accidents to the human body. 

4. The stroke adjusting unit may interfere with 

the mounting bolt when mounting the cylinder 

on the equipment. 

Loosen the unit fixing bolt and dislocate the stroke adjusting 

unit before mounting the cylinder. After fixing the cylinder, 

move the stroke adjusting unit back to the desired location 

and tighten the unit fixing bolt. 

Use caution not to overtighten the fixing bolts.

Caution 

5. Use an external guide for the MY3B stroke 

adjusting unit. 

If a stroke adjusting unit is used where a load is directly applied, 

the collision reaction may cause damage to the cylinder. 

6. Conduct stroke adjustment with an adjustment 

bolt as follows: 

The adjustment bolt should be secured on the same surface 

as the shock absorber after stroke adjustment. 

If the stopper surface of the shock absorber and the end surface 

of the adjustment bolt are not on the same level, it may 

result in an unstable stop position of the slide table or reduced 

durability.

Handling 

If the stroke adjusting unit is used at an intermediate position, 

the energy absorption capacity may be different. Refer to the 

maximum absorbed energy on pages 1134 and 1149 and operate 

within the allowable absorption energy. 

 

Loosen the lock nut for the adjustment bolt, adjust the stroke 

on the head cover side with a hexagon wrench, and secure 

with a lock nut. 

 

Loosen the two unit fixing bolts on the shock absorber side 

and rotate the shock absorber for stroke adjustment. Tighten 

the unit fixing bolts equally to secure the shock absorber. Use 

caution not to overtighten the fixing bolts. 

(Refer to “MY3B/MY3M Stroke Adjusting Unit Tightening Torque 

for Fixing Bolts.”) 

 

Loosen the fixing bolt for the shock absorber. Rotate the 

shock absorber and adjust it. Then, tighten the fixing bolt for 

the shock absorber and secure the shock absorber. Additionally, 

please be careful that the fixing bolt should not be tightened 

excessively. 

(Refer to “MY3M Shock Absorber Tightening Torque for Fixing 

Bolts”.)

8. Do not fix and use the stroke adjusting unit 

at an intermediate position (MY3B/MY3M). 

If the stroke adjusting unit is fixed at an intermediate position, 

an error may result depending on the collision energy. In that 

case, the use of the holder mounting bracket for adjustment is 

recommended. It is provided with the "-X416" or "-X417" 

made-to-order specification. 

(Refer to “MY3B/MY3M Stroke Adjusting Unit Tightening Torque 

for Fixing Bolts.”) 

Service Life and Replacement Period of Shock Absorber 

Caution 

1. Allowable operating cycle under the specifications 

set in this catalog is shown below. 

1.2 million times: RB08 

2 million times : RB10 to RB2725 

Note) Specified service life (suitable replacement period) is the value at 

room temperature (20 to 25°C). The period may vary depending on 

the temperature and other conditions. In some cases the absorber 

may need to be replaced before the allowable operating cycle 

above.

Mounting of Fitting and Speed Controller 

When the stroke adjusting unit is used with MY3B and MY3M, the fittings mountable on the front or back port will be limited to those listed 

below. 

In such cases, since direct mount type speed controllers cannot be mounted, use in-line type speed controllers. (Except MY3B40/63 

and MY3M63)
