  • Ball cages for ball bearings of the angular contact type having a double row of balls with opposed angular contacts
    Patent number: 4082383
    Abstract: A ball cage for a ball bearing of the angular contact type having a double row of balls with opposed angular contacts comprises a solid central portion which is bounded between two concentric cylindrical surfaces and between two parallel planes and has cells with part-spherical surfaces for receiving the balls in each axially directed side. Elastic lips having surfaces which form continuations of the part-spherical surfaces of the cells project from the central portion axially beyond the parallel planes and these lips permit the introduction of the balls into the cells in an axial direction and retain the balls in the cells elastically.
