Patent ID: 7938585

Claim:
A radial rolling bearing, comprising: an outer bearing ring; an inner bearing ring; and a multiplicity of rolling bodies which are arranged between the bearing rings and which are held at uniform distances from one another in a circumferential direction by a bearing cage assembled from two ring halves, the rolling bodies being formed as spherical disks, which have two side faces flattened symmetrically from a basic spherical shape, which are arranged parallel to one another and which roll with running surfaces in two groove-shaped raceways that are incorporated into an inside face of the outer bearing ring and into an outside face of the inner bearing ring, wherein the bearing cage has, for each rolling body, individual cage pockets which surround the rolling bodies along a pitch circle line and in which the rolling bodies, via two low-friction point contacts between center regions of the side faces and longitudinal webs of the cage pockets are axially guided between the bearing rings and have a defined degree of freedom for tilting movements occurring transversely with respect to a running direction and a defined degree of freedom for automatic orientation with respect to a pressure angle of the radial rolling bearing, wherein the center regions of the side faces of the rolling bodies are formed by centric depressions that are incorporated into the side faces, the center regions each having a planer bottom extending radially over a substantial portion of each side face, and by means of the center regions a mass center of gravity of the rolling bodies can be displaced radially outward toward the running surfaces, and wherein the center regions of the side faces of the rolling bodies and the longitudinal webs of the cage pockets are in contact with each other via axial cone apices which are incorporated along a longitudinal center into the longitudinal webs, protrude into the centric depressions in the side faces of the rolling bodies and are in operative contact with the planar bottom of the depressions only at a point of contact.
