Abstract

A cage for a ball bearing, especially for an inclined ball bearing, is comprised of two side rings connected together by webs, with one of the side rings being outside of the pitch circle and the other side ring being inside of the pitch circle. Circumferentially resilient axially extending projections are provided extending from one of the side rings toward the other, radially inwardly or outwardly of the pitch circle, and recesses are formed by the webs and projections in the regions of minimum spacing between the balls.
