Patent ID: 8210754

Claim:
A radial roller bearing for a bearing of shafts in wind power transmissions, comprising: an outer bearing ring with an inner raceway; an inner bearing ring, which is arranged coaxially with respect thereto and has an outer raceway; a multiplicity of roller bodies which roll between the outer bearing ring and the inner bearing ring on the outer raceway and the inner raceway respectively and are held in a circumferential direction by a bearing cage; and hollow rollers arranged between the roller bodies and held in the cage, the hollow rollers aid in preventing slip between the roller bodies and outer bearing ring and the inner bearing ring, and the hollow rollers have a slightly larger diameter and a lower modulus of elasticity than the roller bodies in order to ensure, in a load-free state of the radial roller bearing, a continuous contact with the outer bearing ring and the inner bearing ring and, thus, a continuous drive for the bearing cage and, thus, for the roller bodies at a kinematic rotation speed, wherein the hollow rollers have have further inherent compression stresses of at least −200 MPa, which are superimposed on a maximum load stress of the hollow rollers in addition to the inherent compression stresses which result from a heat treatment of the hollow rollers.
