ROTOLIN Type MS

Type MS SLIDING AND ROTARY MOTION BALL BUSHES

CPE sliding ball bushes are designed to allow unrestricted length of linear travel and consequently, are not suitable for preloading. They are capable of both sliding and rotary motions and provide a sensitive fit, superior to any plain bushings. Sliding ball bushes are eminently satisfactory for a wide variety of purposes not requiring preloading, and particularly suitable for light loading and vertical applications. Being virtually friction-free in operation, they permit high speed performance with freedom from lubrication troubles or risk of seizure.

Bearing reference indicates bearing type, shaft diameter and outside diameter.

Larger, heavy duty and special types are available.
Please contact us to discuss your performance requirements.
CAUTION: Excessive press fits may affect pre load.  If in doubt please contact us for alternative mounting methods.

 

ENGINEERING DATA 

Series "MS" bearings must be used with a clearance fit between the balls and the shaft. The housing and shaft tolerances stated must therefore be strictly adhered to in order to prevent excessive closing in of the bearing sleeve on assembly. The outer race and balls are of 535 A99 steel. Shafts should be hardened to at least 60 HRC and ground to at least 0.25um.
