The invention relates to an axial cage (1) for cylindrical rolling elements, which consists substantially of a thin-walled annular disc (2) having a W-shaped profile cross-section, the individual profile limbs of which are formed by a radially inner rim (3) that is integrally molded on the inner edge of the annular disc (2), by a radially outer rim (4) that is integrally molded on the outer edge of the annular disc (2) and by a U-shaped bead (7) which is connected via straight profile sections (5, 6) to the rims (3, 4) and has the same radial extension as the rims (3, 4). A plurality of rectangular cage pockets (8) arranged at uniform distances apart from each other is worked out of the bead (7) and the adjoining straight sections (5, 6). Between said cage pockets there are pocket webs (9) that connect the rims (3, 4) to one another, wherein said pocket webs hold the cylindrical rolling elements (10) in the cage pockets (8) and guide same in the circumferential direction. According to the invention, the outer rim (4) of the axial cage (1) is designed in a crown cap-like overall shape, as a result of which in the region of each cage pocket (8) the rim (4) has a constriction (12) that extends axially into the cage pocket and is in supporting contact with an end face (11) of the rolling elements (10), and in the region of each pocket web (9) the rim has a section (13) corresponding to the outer diameter of the axial cage (1). |
