Abstract

A pivot bearing having a first bearing surface of hollow cylindrical design, at least in sections. Guided in the first bearing surface is a second bearing surface of hollow cylindrical design, at least in sections. Rolling bodies are arranged between the bearing surfaces. The pivot bearing also has a cage for guiding the rolling bodies, and a slide block to prevent the cage from slipping. A first grove is formed in the first bearing surface and a second grove is formed in the second bearing surface. The groves are inclined transversely with respect to the running direction of the rolling bodies. The opposite inclination of the groves has the result that, if the spacing between the bearing surfaces is neglected, the grooves intersect. The sliding block is guided between the grooves. The cage has a recess that holds the sliding block permitting cage control.
