Abstract
A solid cage for roller bearings, where the pitch circle of the rollers is between the radial center of the cage and its bore, with guide surfaces on the webs which conform to the lateral surface of the rollers, thus forming retaining edges in the area of the bore, across which the rollers are snapped into the pockets, characterized in that the guide surface 4 is interrupted by at least one strip 10, which curves to form an arc facing the roller 3, this strip being recessed into the guide surface 4 in the radially outward area of the cage, but projecting beyond the guide surface 4 in the radially inward area to serve as an additional retaining projection 12 for the roller3.
