Abstract
A separator or cage for ball bearings has a plurality of pockets. Each pocket has an internal pocket surface toward the ball. At each half of the pitch circle of the pocket around the ball there are two approximately cylindrical first surface sections which are spaced nearer to the ball, a respective spherically curved second pocket surface section which extends over the respective pole of the ball and which has a diameter smaller than the ball, and a respective third pocket surface section which extends over the equator of the ball at each circumferential end of the pocket and which has a larger diameter than the ball. The pocket surface provides good lubrication support for the ball to minimize rubbing of the ball against the separator pocket surface.
