an axial cage (1) for cylindrical rolling bodies which substantially is formed of a thin-walled washer (2) with a W-shaped profile, the individual profile legs of which are formed by an inner radial rim (3) formed on the inner edge of the washer (2), an outer radial rim (4) formed on the outer edge of the washer (2) and a U-shaped center crimp (7) connected by way of inner and outer axial profile sections (5, 6) to the radial rims (3, 4) and having the same radial extent as the rims (3, 4). A number of evenly spaced rectangular cage pockets (8) are cut from the central crimp (7) and the adjacent axial profile sections (5, 6), between which pockets an equal number of pocket webs (9) are formed connecting the rims (3, 4) with one another, by which webs the cylindrical rolling bodies (10) are retained in the cage pockets (8) at uniform distances from one another and are also guided in the circumferential direction. According to the invention, this axial cage (1) is characterized in that the outer radial rim (4) is formed with an inclination (α) facing away from the central U-shaped crimp (7) and the cage pockets (8) have an axial length greater than the smallest axial distance between the inner sides (11, 12) of the inner and the outer radial rim (3, 4) such that the cage pockets (8) extend at least into the outer radial rim (4) of the axial cage (1) and, because of a crowned formation of the outer face sides (13) towards the center of the pocket on the outer radial rim (4) of the axial cage (1) at the height of the roll axes of the rolling bodies (10), form a rounded thrust lug (14) for the outer end faces (15) of the rolling body (10).
An axial cage for cylindrical rolling bodies, comprising a thin-walled washer with a W-shaped profile, individual profile legs of which are formed by an inner radial rim formed on an inner edge of the washer, an outer radial rim formed on an outer edge of the washer and a U-shaped center crimp connected by way of inner and outer axial profile sections to the inner and outer radial rims and having a same radial extent as the inner and outer radial rims, a number of evenly spaced rectangular cage pockets are cut from the center crimp and adjacent ones of the axial profile sections, between said pockets an equal number of pocket connecting pieces are formed connecting the inner and outer radial rims with one another, said connecting pieces acting to retain the cylindrical rolling bodies in the cage pockets at uniform distances from one another and to guide the cylindrical rolling bodies in a circumferential direction, the outer radial rim is formed with an inclination angle (α) facing away from the U-shaped center crimp and the cage pockets have an axial length greater than a smallest axial distance between inner sides of the inner and the outer radial rims such that the cage pockets extend at least into the outer radial rim of the axial cage and, outer end faces of the cage pockets have a crowned formation extending towards a center of the pocket on the outer radial rim of the axial cage at a height of the rolling axes of the rolling bodies that form rounded thrust lugs for respective outer end faces of the rolling bodies.
