An outer ring for a roller bearing includes a raceway produced from a bearing steel. The outer ring is made of a metal strip wound to form a raceway tube and a cladding tube which is connected thereto and which surrounds the raceway tube on the outer side.

Outer ring and roller bearing comprising said type of outer ring

A running ring () for a sleeve bearing, the running ring substantially including a cylindrical outer casing () or inner casing, the inner circumferential surface () or outer circumferential surface of which is formed as a raceway for bearing rollers, and two rims, which are formed on the axial end faces of the outer casing () or the inner casing and are oriented radially inward () or outward, said rims being provided as an axial guide for the bearing rollers. According to the invention, the running ring () is characterized in that the two rims () have a same wall thickness, and the two rims () are produced by radially flanging over two grooves formed into the edge regions of the inner casing surface or the outer casing surface of a cylindrical starting sleeve, said grooves forming two recesses after the flanging process, wherein the recesses are arranged at a transition between the inner faces of the rims () and the inner circumferential surface () of the outer casing () or the outer circumferential surface of the inner casing and are formed as lubricant reservoirs with a variable volume.

Running ring for a sleeve bearing

A radial rolling element bearing () formed of a cylindrical outer ring () that is inserted into a housing (), and a rolling element cage () arranged in said outer ring and formed by a plurality of roller-shaped rolling bodies () which are inserted into a bearing cage () and held thereby, equidistantly, in a circumferential direction, and roll on an outer raceway () formed by the inner lateral surface () of the outer ring, and on an inner raceway () formed by the outer lateral surface () of a shaft () to be mounted or a smooth cylindrical inner ring pushed onto said shaft. The roller race is axially guided by two separate flanged disks () which lie against the axial sides () of the outer ring and are axially secured, together with the outer ring, by securing elements which engage in recesses () in the housing. According to the invention, this radial rolling element bearing is characterized in that said flanged disks include a right-angled profiled cross-section that has a horizontal securing leg () and a vertical flanged leg () and, by pressing their horizontal securing legs onto two peripheral stepped shoulders () in the edge regions of the outer lateral surface () of the outer ring, are secured thereto; and in that the securing elements which engage in recesses in the housing for the purpose of axially securing said rolling element bearing are designed as spring elements () integrated into the securing legs of the flanged disks.
