A cage for ball bearings consists of two side rings connected together by webs, and having ball pockets with ball pockets having curved partial surfaces inside and outside of the pitch circle and displaced from one another in the axial direction. In this arrangement the rubbing between the walls of the cage pockets and the balls is very small and free space is provided for receiving a lubricant. The pocket walls of the cage sections lying in the region of one or the other of the side rings has several radially-overlying zones, with conical surfaces, the conical surfaces being arranged at different inclinations to the bearing axis.

An antifriction bearing has an inner race with a radially outward extending flange, an outer race, and rolling elements between the inner and outer races. The surface of the outer race toward the flange has a sealing lip, and an annular flexible resilient sealing element engages the lip and extends into sliding contact with the flange. The sealing element is held in place by a cylindrical casing radially surrounding the sealing element, the casing extending axially to form a narrow gap with the flange.
