The rolling bearing cage (1) has an annular base contour with receiving pockets (2) that are arranged for receiving rolling elements. A reinforcing element (3) is arranged inside the base contour. The reinforcing element is formed as metallic structure, and is covered by injection molded plastic material. The reinforcing element is shaped such that the reinforcing element is partially equidistant from the surface of the functional area of the receiving pockets.
