Motor attachment via sidedrive with timing beltFor Linear Motion Slides from size 25-160and up, the motor can be attached via aside drive with timing belt. This results ina shorter overall length compared to amotor attachment with motor mount andcoupling.
The compact enclosed housing providesbelt protection and secures the motor.
In addition, different gear ratios are available:
i = 1 : 1
i = 1 : 1.5 (size 25-160, 30-180)
i = 1 : 2 (size 40-230, 50-280)The side drive with timing belt can bemounted in four directions:
– bottom, top (RV01 and RV02)– left, right (RV03 and RV04)

Motor attachment with mountand couplingA motor can be attached via a mountand coupling to all Linear Motion Slidesequipped with a ball screw drive.
The motor mount serves both to attach themotor to the Linear Motion Slide and as anenclosed housing for the coupling.
The coupling transmits the motor drivetorque free of stresses to the LinearMotion Slide drive shaft.
Our standard couplings compensate forthe thermal expansion of the system.
If other makes of couplings are used, the ther-mal expansion must be taken into account.

Reduced load capacity in short-stroke applications
In short-stroke applications, the service lifeof the shafts is shorter than that of theSuper Linear Bushings.
For this reason, the load capacities listedin the tables must be multiplied by thefactor fw.

STAR – Linear Motion SlidesGeneral Information
tan αmax = 8.72 · 10-3 =̂ 0.5°
tan α ≤ tan αmax
Linear Motion Slides are also available with:
- corrosion resistant steel shafts to DIN 17230 / EN 10088
- STAR Resist steel shafts: zinc/iron coating with yellow chromating
For further details on STAR Resist, please ask for catalog RE 82 050.
For further details on STAR Linear Bushings and Precision Steel Shafts,please ask for catalog RE 83 100.
Delivered as separate parts. The carriage is mounted as a sub-assembly.The fixing screws are not included in the package.
Open Type SOO:
The Precision Steel Shafts are screwed to the Shaft Support Rails.
tan αmax = 10 · 10-4Size 8-65:
Assemblies without drive unit:
Delivery condition:
Length L:
Assemblies with drive unit: The Linear Motion Slides with ball screw drive and toothed belt drive(SGK, SGR, SOR and SOK) are delivered fully assembled and greased.
Linear Motion Slides consist of components of varying length and assemblies of fixedlength. The length-dependent components are cut to size to suit each particular appli-cation. Linear Motion Slides can thus be custom-designed and completed in a variety oflengths (infinitely variable). Lengths exceeding the specified maximum Lmax are availableon request.
Permissible shaft deflection inthe Linear Bushing closed type:
Due to the use of STAR Super Linear Bushings (except for Linear Motion Slidesize 8-65), higher shaft deflection is permissible than for conventional linear bearings.Selection of the length (L) and the size of slide should take account of the permissibleshaft deflection (tan α).
Maximum permissible drivetorque Mper:
The values of Mper given in the graphs (see Technical Notes) are based on the followingassumptions:
• Horizontal operation
• No radial load on the ball screw drive journal
• The torque rating of the coupling is not taken into account
The maximum permissible drive torque (see Technical Notes) is reduced for ball screwdrives with keyway. The keyway produces a notch effect and reduces the effective dia-meter. (Information on side drive with timing belt available on request.)
