Abstract

A spherical roller thrust bearing comprises two bearing rings rotatably guided by spherical roller elements for rotation about an axis. The roller elements are spaced circumferentially apart by a segmented retainer comprising separate retainer segments spaced apart in the circumferential direction. Each retainer segment includes opposite circumferentially facing surfaces engaging adjacent roller elements. Each surface includes at least one projection making point contact with a peripheral surface of a roller at a location whereby the force transmitted between the roller elements by the segments excludes a radially inward force component. The projections are located relative to the roller elements such that the segments tend to hang upon the roller elements.
