An axial rolling bearing unit includes a first annular axial bearing washer, a second annular axial bearing washer, a bearing cage, and rolling elements arranged between the first annular axial bearing washer and the second annular axial bearing washer. The bearing cage includes an inner radial edge rim extending in an axial direction to radially guide the rolling elements, and an outer radial edge rim extending in the axial direction to radially guide the rolling elements. The inner radial edge rim or the outer radial edge rim includes an end-side bend extending in an opposite axial direction as a double-rim design, and the end-side bend has a first distal end section that holds the first annular axial bearing washer in a form-fitting manner. The other one of the inner radial edge rim or the outer radial edge rim holds the second annular axial bearing washer in a form-fitting manner.
An axial rolling bearing unit with rolling elements which are arranged between two annular axial bearing washers and which are guided by means of a bearing cage formed from a sheet metal material, said bearing cage having an inner and outer radial edge rim extending in the axial direction in order to radially guide the rolling elements, wherein at least one of the edge rims is provided with an end-side bend in the opposite direction thus having a double-rim design, wherein the distal end section thereof is designed to hold the first axial bearing washer in a form-fitting manner, and an edge rim of the bearing cage lying opposite the double rim is designed to hold the second axial bearing washer in a form-fitting manner, in order to create an overall self-retaining structural unit.
An axial rolling bearing unit comprising:
