Torque Resistant Flanged Ball Bushings
The Torque-Resistant Flanged Ball Bushings have the same basic boundary dimensions as the bushings shown on page 18. They are equipped with 3 ball races for the two smallest bushings and 4 ball races for the larger bushings.
In order to ensure a very compact and easy to mount design the wall section and the ball diameters are optimized. This saves the precise manufacture of the mating parts.
