ROTOLIN Type MSF

Type MSF SLIDING AND ROTARY MOTION BALL BUSHES

 

Flanged types of Rotolin sliding ball bushes are made a "push fit" into bored holes of correct diameter. This avoids any possible closing-in of the outer sleeve which could result in preloading and impair the ultra-smooth working action, it also serves to facilitate installation in their operating stations. These ball bushes are capable of providing first class, sliding fit on precision shafts without restriction on the length of travel, they are extensively employed for their adaptability, reliabity and general efficiency in service.

ENGINEERING DATA 

 

Series "MSF" 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.
