  • Sealing assembly for clutch release bearing
    Patent number: 5580176
    Abstract: Two annular sealing members are mounted at opposite ends of an anti-friction bearing to prevent leakage of lubricant out of the bearing. One of the sealing members includes a rigid annular plate having a molded elastomeric protuberance extending into an annular groove in an end surface of an inner race of the anti-friction bearing. The protuberance maintains concentricity and limits radial shifting between the sealing element and the bearing assembly.
