  • Ball plug for a bearing race
    Patent number: 9488224
    Abstract: A ball plug seals a bearing race holding ball bearings and grease. The plug has a rubber body with a pair of metal disks on an upper surface. The metal disks are separated by a gap so that when they are urged toward one another, the rubber body is compressed. This allows the outer periphery of the metal disks to be received in a mating circumferential groove provided adjacent an end opening of the bearing race. Upon release of the metal disks, the rubber body relaxes and the plug is securely retained within the opening of the bearing race.
