An injection-molded rolling-element bearing cage has a radially outer-lying surface, a radially inner-lying surface, first and second radial walls connecting the radially outer-lying surface and the radially inner-lying surface, and a plurality of receiving pockets configured to receive rolling elements. The receiving pockets are spaced from the first radial wall by a first annular band of the radially inner-lying surface and from the second radial wall by a second annular band of the radially inner-lying surface, and at least one projection extends radially inward from the radially inner-lying surface into a spaced defined by the radially inner-lying surface, at least part of the at least one projection being located in the first annular band.
