Abstract

A ball bearing with a cylindrical ball cage intermediate a shaft and outer shell, and alternately spaced longitudinal load portions and ball-return paths in the bore of the shell, has additional longitudinal recesses in the bore for receiving with play a mating longitudinal rib on the cage, which permits restricted lateral and circumferential movement of the balls relative to the shell during longitudinal movement of these balls.
