A ring-shaped metal rolling bearing cage, which has cage pockets for receiving rolling elements. The cage is formed by a first and a second cage segment. Adjoining ends of the cage segments are connected to one another by suitable connection assemblies. At least one of the assemblies permits a change of the cage diameter when the cage temperature changes. The suitable assembly, on one side, is configured as a joint mechanism and, on another side, as a locking mechanism, and at least one of the assemblies has a lash. A rolling bearing cage configured with the joint mechanism and the locking mechanism can be mounted with low time expenditure in a simple and reliable manner over a shaft, particularly in the case of an idler pinion mourning.

Ring-shaped rolling bearing cage

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

A rolling bearing cage, which has two annular elements and cage crossbars connecting the annular elements to each other so as to form pockets for receiving rolling elements arranged between every two adjacent cage crossbars and the annular elements. The cage crossbars have an elastic configuration. Also, a rolling bearing is disclosed that has a rolling bearing cage.

Rolling bearing cage and 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).

Rolling element cage

A multi-row rolling bearing, which has a cage for rows of rolling elements that is detachably connected to a respective adjoining cage. For assembly and safety of assembly, the detachable connection between the cages is at least one predetermined breaking point.

Multi-row rolling bearing

A needle roller bearing, which has a rimless inner ring or a rimless inner ring bushing and a plurality of rolling elements that are arranged and rotatable in the cage. For coherence of the needle roller bearing after manufacturing and for mounting in an installation space, the cage has, at least on one front end, a radially inward pointing retaining device and the inner ring or the inner ring bushing has a retaining element on its outer periphery that cooperates with the retaining device.
