Abstract

A slip-free rolling bearing (1) is provided, in the outer ring (3) of which there is formed an encircling groove (7). The rolling bodies (2) of this rolling bearing are surrounded, in the manner of an envelope circle, by a central ring (8) and are in physical contact therewith. To ensure permanent drive of the rolling bodies, the central ring is inserted into the groove so as to be radially free but is fixed rotationally fixedly in said groove, wherein a radial depth of the groove is greater than a thickness of the central ring. The rotational fixing of the central ring in the groove of the outer ring is effected by a spring element.
