Abstract

The invention concerns a rolling element cage (32) made of a metal strip material that is profiled, stamped, cut to length, and bent into a round shape, wherein the ends of the cut-to-length strip sections are joined together by welding. In order to make it possible to influence the lubricant distribution in the bearing and the vibration characteristics of the cage and thus of the overall bearing system, according to the invention the strip section ends (34, 36) are joined together with a predetermined axial offset (a) and/or radial offset (b).
