Patent ID: 7891880

Claim:
A radial rolling bearing, comprising: an outer bearing ring; an inner bearing ring; and a plurality of rolling bodies which are arranged between the outer bearing ring and the inner bearing ring and which are held at uniform intervals with respect to one another in a circumferential direction by means of a bearing cage which is composed of two ring halves, with the rolling bodies being formed by spherical disks which have in each case two side surfaces, which are flattened symmetrically from a spherical basic shape and are arranged parallel to one another, and which roll with running surfaces in two groove-shaped raceways which are formed into an inner side of the outer bearing ring and into an outer side of the inner bearing ring, wherein the bearing cage has individual cage pockets for each of the rolling bodies, the cage pockets surround the rolling bodies on a pitch circle line and in the cage pockets the rolling bodies, by means of at least two low-friction lines of contact between side surfaces and longitudinal webs of the cage pockets, are firstly axially guided between the bearing rings and are secondly formed with a defined degree of freedom for self-alignment to a pressure angle of the radial rolling bearing, wherein central depressions are formed in the side surfaces of the rolling bodies, providing a lubricant reservoir for the radial rolling bearing and by means of which depressions a mass center of gravity of the rolling bodies can simultaneously be moved radially outward toward the running surfaces, and wherein axial wedge-shaped depressions are formed in the longitudinal webs of the cage pockets, extend over an entire width of the side surfaces of the rolling bodies and are in guiding contact with the side surfaces of the rolling bodies at two points each so as to prevent penetration by the axial wedge-shaped depressions into the central depressions of the rolling bodies.
