Patent ID: 8262293

Claim:
A radial rolling bearing, comprising: an outer bearing ring; an inner bearing ring; and a multiplicity of rolling bodies which are arranged one next to the other in two rows between the inner bearing ring and the outer bearing ring and are held at uniform distances from one another in a circumferential direction by means of two bearing cages, at least one row of which is embodied as ball rollers with two side faces which are flattened symmetrically from a basic ball shape and are arranged parallel to one another, wherein the two rows of the rolling bodies roll in two adjacent groove-shaped raceways which are formed in an inner side of an outer bearing ring and in an outer side of the inner bearing ring, wherein the contact angle axes of the raceways are positioned obliquely with respect to one another and are bounded, in each case, axially on one side by one shoulder, wherein additional free space contours and supporting contours are integrally formed at least on the raceways arranged in the outer bearing ring and in the inner bearing ring of one of the rows of rolling bodies and, in each case, in a region of axial edge parts lying opposite the shoulders of the raceways, by means of the free space contours and the supporting contours, the ball rollers can be fitted into angular contact through axial insertion into a distance between the outer bearing ring and the inner bearing ring and subsequent tilting into the raceways, and wherein, arranged as an additional supporting contour in the inner bearing ring is a central rim, which is wedge-shaped in cross-section, opens with wedge faces into the raceways of the bearing ring and is provided for carrying out pivoting guidance during the tilting of the ball rollers into the operating position in the raceways of the two bearing rings.
