Abstract
A radial roller bearing arrangement in which at least one retaining projection is provided as an anti-rotation feature of an outer ring. The projection is located on an inner diameter of a fixed rim formed on one axial side of the outer ring, so that the outer ring can be implemented with a radially inward-pointing flanged rim on its other axial side that can be formed after insertion of a needle roller and cage assembly to act for holding the needle roller and cage assembly in the outer ring.

Radial roller bearing arrangement, in particular for a needle bushing (1), consisting essentially of a thin-walled outer ring (4) that is formed without cutting and can be placed in a bore (2) of a housing (3) and that has on one axial side a radially inward-pointing fixed rim (5), and also consisting of a needle roller and cage assembly (7) that is placed in the outer ring (4) and that is composed of a needle cage (8) and a plurality of bearing needles (9) that are guided therein in the circumferential direction with uniform spacing and that roll on the inner circumferential surface (10) of the outer ring (4) and on the outer circumferential surface (11) of a shaft (12) that is to be supported or of a separate inner ring, wherein the needle bushing (1) is additionally designed with means for retaining the needle roller and cage assembly (7) in the outer ring (4) and has, in at least one circumferential location, a retaining projection (13) that engages the housing (3) as an anti-rotation feature of the outer ring (4), characterized in that the at least one retaining projection (13) provided as an anti-rotation feature of the outer ring (4) is located on the inner diameter of the fixed rim (5) formed on one axial side of the outer ring (4), so that the outer ring (4) can be implemented with a radially inward-pointing flanged rim (6) on its other axial side that can be formed after insertion of the needle roller and cage assembly (7) to act as means for holding the needle roller and cage assembly (7) in the outer ring (4).
