Compact Linear Actuator with Ball Screw Drive - Schaeffler Group

Compact Linear Actuator 

with Ball Screw Drive

High load capacity, rigid, 

cost-effective, precise 

Foreword 

In many applications (for example in the handling and automation 

sector), small loads must be moved reliably, quickly and accurately. 

Furthermore, there is often very little space available to 

accommodate handling systems. 

For these applications, we have developed our new compact linear 

actuators of series MKUVS32. 

The new compact linear actuators are standard, ready-to-fit compact 

actuators with high rigidity and load carrying capacity. 

They can support forces from all directions (apart from the direction 

of motion) and moments about all axes. 

They contain a precise guidance system, a rigid support rail and a 

precise drive unit with a high precision spindle. 

Accessories The comprehensive standard range can be further optimised by 

means of a range of accessories precisely matched to various 

application requirements.

Features Compact linear actuators MKUVS32 comprise a support rail, 

one or two carriages guided in the support rail and a high precision 

ball screw drive. 

The carriage is guided in the support rail by means of two or four 

linear recirculating ball bearing units KUVS32. 

Due to their wide base and small height, the linear actuators of 

the SLIVER series allow high performance within compact 

dimensions. 

These linear actuators allow accelerations of up to 30 m/s 2 

and travel speeds of up to 1 m/s. 

The maximum stroke length is 1022 mm. 

Applications The compact linear actuators can support forces from all directions 

and moments about all axes. They offer high load carrying capacity 

with high precision. 

They are highly suitable for applications in: 

■ assembly systems, for example in semiconductor production 

■ inspection and measurement systems 

■ medical equipment 

■ electronic component manufacture 

■ handling systems 

■ automatic welding equipment. 

Sealing In order to protect the linear guidance system and drive spindle 

against contamination, linear actuators MKUVS32 can be supplied 

with strip covers made from alloy sheet steel (suffix ADA). 

In this design, the carriages are produced with a covering strip guide 

on both end faces. As a result, the stroke length is reduced. 


Support rail The support rail is a composite rail, Figure 1. It comprises a profiled 

carrier rail made from anodised aluminium and a guideway for the 

linear recirculating ball bearing units. The integral slots allow simple 

mounting of end position and zero point sensors. 

The maximum length of the support rail is 1100 mm. 

Figure 1 

Support rail 00014A46 

Carriage The carriage consists of an anodised aluminium saddle plate, 

the spindle nut and two or four linear recirculating ball bearing 

units KUVS32, Figure 2. It is driven by means of the ball screw drive. 

The linear guidance system and the spindle nut can be relubricated 

via two lubrication nipples on each of the longitudinal faces. 

The carriage has an integrated magnet for Hall sensors. 

Figure 2 

Carriage 00014A45 




Longer carriage or two carriages In order to support higher loads, linear actuators with a longer 

carriage are available (suffix 80). 

Linear actuators with carriages of the standard or long design 

are also available with two carriages arranged in series. 

The second carriage is not driven and is freely movable. 

Location The carriage has threaded holes for fixing to the adjacent 

construction. 

Ball screw drive The high precision ball screw drive is available with a pitch of 2 mm, 

4 mm, 10 mm or 20 mm. 

The ball screw drive has a pitch accuracy of 52 �m/300 mm and a 

repeat accuracy of �20 �m for L 2 � 550 mm. 

The maximum spindle speed is 3 000 min –1 .

Lubrication The guidance systems and the ball screw drive in the compact linear 

actuators are supplied with an initial grease filling of a high quality 

lithium complex soap grease KP2P–35 to DIN 51 825 and must be 

relubricated during operation. 

Lubrication of the guidance systems The guidance systems and the ball screw drive (the contact zones 

between the rolling elements and raceways) must be lubricated. 

The relubrication intervals are essentially dependent on the carriage 

travel speed, the load, the operating temperature, the stroke length 

and the environmental conditions. The cleaner the environment, 

the lower the lubricant consumption. 

The carriage must be moved during the lubrication process. 

The carriage must be moved slowly during relubrication 

of the spindle nut (Figure 6 � or �). 

Relubrication should be carried out using a lithium or lithium 

complex soap grease with a mineral oil or poly-alpha-olefin base. 

If different greases are used, their miscibility and compatibility 

must be checked first. 

The viscosity of the base oil should be in the range ISO-VG 68 

to ISO-VG 100. The consistency corresponds to NLGI class 2. 

The grease must have particular anti-wear characteristics at loads of 

C/P � 8. This is indicated by the letter P in the DIN designation, 

for example: DIN 51 825–KP2P–35. 

Relubrication should be carried out wherever possible with several 

partial quantities at various times instead of the complete quantity 

at the time of the relubrication interval. 

Relubrication is carried out via three lubrication nipples on 

the longitudinal faces of the carriage. 

Lubricant must be supplied to the guidance system from the left 

and right (lubrication points � and �) and can be supplied to 

the ball screw drive from the left or right (lubrication point � or �). 

�, � Lubrication points for the linear 

recirculating ball bearing units 

�, � Lubrication points for the spindle nut 

Figure 6 

Lubrication points 

For relubrication, a conical or needlepoint grease nozzle must be 

used to press the lubricant into the lubrication nipple.

00014863

The threads of the lubrication nipples can also be used for 

connection to a central lubrication system. 

The grease gun, lubrication nipple, vicinity of the lubrication nipple 

and grease must be clean. 

Lubrication should always be carried out with the linear actuator 

warm from operation. 

Move the carriage during lubrication. 

Move the carriage slowly during relubrication of the spindle nut 

(� or �). 

Calculation of lubrication intervals Since it is not possible to calculate all the influencing factors, 

the time at which relubrication must be carried out and the quantity 

of lubricant which must be used can only be precisely determined 

under actual operating conditions. 

If no precise data are available, the values for many applications can 

be taken from the table. 

Relubrication must be carried out at the latest when fretting 

corrosion first occurs, which is visible as a reddish discolouration 

of the raceways. The subsequent lubrication intervals must be 

shortened. 

An approximation formula can be used, however, to determine 

a guide value for many applications. 

Detailed information on calculating the grease operating life is given 

in the Catalogue PF 1, Monorail Guidance Systems.

Any lubrication method involves loss of lubricant. 

The used lubricant must be collected and disposed of by methods 

that help to protect the environment. 

The handling and use of lubricants is governed by national 

regulations for environmental protection and health and safety 

at work as well as information from the lubricant manufacturers. 

These specifications must be observed. 




Location of the support rail 

Location using clamping lugs Clamping lugs are suitable for location of the linear actuator on 

the adjacent construction. If the actuator is fully supported, 

clamping lugs must be arranged at both ends of the support rail 

and then on both sides at intervals of no more than 300 mm, 

Figure 7. 

For heavy load conditions are present, the quantity of clamping lugs 

must be increased! 

Figure 7 

Location using clamping lugs 

Location using screws For location of the linear actuator on the adjacent construction, 

the underside of the support rail has threaded holes at intervals 

of 40 mm, Figure 8. 

The end distance T 2 is dependent on the profiled rail length and the 

number of holes. It is a minimum of 15 mm and a maximum of 

35 mm.

Accuracy 

Support rail The support rail of the compact linear actuator is precision 

straightened. The tolerances are maximum values and are not valid 

for unmounted support rails. When mounted, the shape of the 

extruded profile adapts to the mounting surface. The method 

for determining the straightness of the support rail is shown in 

Figure 10.
