A rolling bearing comprising a rolling bearing cage having a plurality of rolling element pockets arranged in at least one row to receive at least one row of rolling elements, two lateral rings and a plurality of crosspieces connecting the two lateral rings, such that the plurality of rolling element pockets are formed between the plurality of crosspieces, and at least one empty pocket. The rolling bearing cage includes fewer rolling elements in the at least one row than the number of rolling element pockets, such that the at least one empty pocket does not receive a rolling element. A method for producing a rolling bearing cage is also provided.

Rolling bearing

The invention concerns a rolling element cage () 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 () are joined together with a predetermined axial offset (a) and/or radial offset (b).
