Axial rolling bearing unit with rolling bodies, which are arranged between annular axial bearing washers, and a functionally integrated bearing cage

An axial rolling bearing unit comprising:

• a first annular axial bearing washer;
• a second annular axial bearing washer;
• a bearing cage formed from a sheet metal material, the bearing cage comprising:
• an inner radial edge rim extending in an axial direction;
• and
• an outer radial edge rim extending in the axial direction;
• and
• rolling elements arranged between the first annular axial bearing washer and the second annular axial bearing washer, the rolling elements being radially guided by the inner radial edge rim and the outer radial edge rim, wherein:
• at least one of the edge rims comprises an end-side bend, the end-side bend adjoining a first bend portion and a second bend portion folded over the first bend portion to define a double-rim configuration;
• the first bend portion extends in a first axial direction toward the first annular axial bearing washer, and the second bend portion extends in a second axial direction, opposite the first axial direction, toward the second annular axial bearing washer;
• and
• a first distal end section of the second bend portion forms a first rim border that holds the second annular axial bearing washer in a form-fitting manner.
