  • Piston bearing unit, clutch, transmission and locking differential having the piston bearing unit
    Patent number: 10119573
    Abstract: A piston bearing unit having an actuating piston which has a receiving region. The actuating piston is designed to actuate an element by way of a linear movement. The piston bearing unit also comprises a bearing having a first raceway and a second raceway, wherein the bearing is designed for mounting the actuating piston rotatably with respect to the element. The first raceway and the second raceway are at least partially accommodated in the receiving region.
    Type: Grant

  • Sealing lip for a low friction bonded piston seal
    Patent number: 10100931
    Abstract: An annular seal for a low friction bonded piston seal is provided. The annular seal having a central axis and including an annular seal body symmetrically positioned about the central axis. The annular seal is integrally molded to the body and provides a lower seal lip body, and a top seal lip. The top seal lip including a first radial lip thickness T1 and a second radial lip thickness T2. A ratio between second radial lip thickness T2 to first radial lip thickness T1 is less than 1.00. The annular seal includes a radial lip height H, and a radial lip overall pressure received thickness T3. A ratio of radial lip height H to second radial lip thickness T2 is greater than or equal to 0.65. The radial lip overall pressure received thickness T3 is less than or equal to 0.8 mm. The first radial lip thickness T1 is less than or equal to 0.7 mm.
