Abstract

A thrust ball bearing has an outer cup-shaped ring and an inner cup-shaped ring. A ball bearing assembly of a plurality of balls and a cage is arranged between the closed ends of the bearing rings. The closed bottom of the outer ring is curved, with the center of curvature being on the side thereof toward the bearing assembly. The bearing rings have thin walls, and the thrust ball bearing is particularly adaptable for use as a clutch throw-out bearing.
