Abstract
A radial rolling bearing, which has an outer bearing ring, an inner bearing ring, and rollers, which are arranged between the bearing rings and held at uniform distances from one another in a peripheral direction by a bearing cage in individual cage pockets. The rollers are spherical disks that have parallel lateral surfaces which are symmetrically flattened from a basic spherical shape and which roll in groove-type raceways with their faces. The raceways are incorporated into the inner face of the outer bearing ring and the outer face of the inner bearing ring. The rollers are axially guided between the bearing rings via two low-friction line contacts between lateral surfaces and the longitudinal webs of the cage pockets. The rollers are configured to have a defined degree of freedom for self-alignment to the pressure angle of the radial rolling bearing.
