    摘要: The invention concerns a rolling bearing with a rolling bearing cage (1) having a plurality of rolling element pockets (2) arranged in at least one row to receive at least one row of rolling elements, wherein the rolling bearing cage (1) consists of two lateral rings (3) and a plurality of crosspieces (4) connecting them, between which crosspieces are formed the rolling element pockets (2), and having at least one empty pocket (5). In order to achieve cost-effective manufacture of the rolling bearing cage (1) with the fewest possible changes as compared to a rolling bearing cage fully populated with rolling elements, provision is made according to the invention that the rolling bearing cage (1) is equipped with fewer rolling elements in one row than corresponds to the number of rolling element pockets (2), causing the rolling bearing cage (1) to have empty pockets (5) without rolling elements in the at least one row of rolling element pockets (2). The empty pockets (5) can be implemented in a simple manner by omitting one or more rolling elements, so that storage spaces for lubricant are created. Furthermore, the empty pockets (5) can be formed by targeted shaping in such a manner that a conveying or pumping action is produced in at least one direction of rotation. The invention also concerns a method for producing such a rolling bearing cage.

    摘要: 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).
