Abstract
A radial antifriction bearing which has an outer bearing ring, an inner bearing ring and a multitude of rollers, arranged between the bearing rings and held by a bearing cage. The rollers are configured as spherical disks that each have two parallel lateral surfaces which are symmetrically flattened from a basic spherical shape. The bearing cage has cage pockets in which the rollers are axially guided between the bearing rings via two low-friction point contacts between the center areas of their lateral surfaces and the longitudinal webs of the cage pockets. The rollers have a defined degree of freedom for tilt movements exerted at an angle to the running direction and a defined degree of freedom for self-adjustment to the pressure angle of the radial antifriction bearing.
