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 radial-roller antifriction bearing arrangement, in particular for a needle sleeve (), which includes a thin-walled outer ring (), which can be inserted into a bore () of a housing () and which has two radially inwardly directed rims (), and of a needle ring () which is held in the outer ring () by said rims (). Here, the needle ring () is formed by a needle cage () and by a multiplicity of bearing needles () guided therein at uniform intervals in the circumferential direction, which bearing needles roll on the inner lateral surface () of the outer ring () and on the outer lateral surface () of a shaft () to be mounted or of a separate inner ring. Furthermore, axially adjacent to the side surfaces () of the needle cage () there are arranged at least two seals () which protect the needle sleeve () against dirt from the outside and against loss of lubricant. At least one of the seals (or) is formed from an elastomer as a multi-lip seal composed of at least two component rings () arranged adjacent to one another, which multi-lip seal extends over that part of the inner lateral surface () of the outer ring () which is arranged between the associated rim (or) of the outer ring () and the adjacent side surface (or) of the needle cage () and over the inner lateral surface (), the end surface () and the outer lateral surface () of the rim (or).

A radial roller bearing assembly, in particular for a needle bush (), which substantially comprises a thin-walled outer ring (), which can be inserted into a bore () or a housing (), having two ribs () directed radially inward, and a needle cage assembly () that is held in the outer ring () by said ribs (). According to the invention, the needle cage assembly () is formed by a needle cage () and a plurality of bearing needles () guided therein in the circumferential direction at regular distances, which roll on the inner shell surface () of the outer ring () and on the outer shell surface () of a shaft () to be borne or a separate inner ring. Furthermore, at least two seals () are arranged axially next to the side surfaces () of the needle cage () which protect the needle bush () from contamination from the outside and from the loss of lubricant. According to the invention, at least one of the seals (or) is formed as a multi-lip seal, made of an elastomer, consisting of a single ring, which extends over the part of the inner shell surface () of the outer ring () arranged between the related rib (or) of the outer ring () and the adjacent side surface (or) of the needle cage () and over the inner shell surface (), the face () and the outer shell surface () of the rib (or).

Radial roller bearing assembly, in particular for a needle bush

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.
