A cage for a ball bearing comprised of two generally ridge-shaped ring parts, the respective axially projecting ridges of which are cooperatively placed to define respective pockets for the balls. The plane of separation between the two ring parts is shifted axially off the center and toward one of the ring parts. In the ring part with the axially larger ridges, the circumferentially opposite ends of the respective ridges are at least nearly flat, in the plane through the centers of the balls. The axially deepest surfaces of the ridges are also at least nearly flat, at the axially opposite sides of the cage, which is generally in the respective axial plane through the center of each ball. This prevents jamming of the balls, even in the case of defective manufacture or defective connection of the ring parts. |
