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.

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 Tand a second radial lip thickness T. A ratio between second radial lip thickness Tto first radial lip thickness Tis less than 1.00. The annular seal includes a radial lip height H, and a radial lip overall pressure received thickness T. A ratio of radial lip height H to second radial lip thickness Tis greater than or equal to 0.65. The radial lip overall pressure received thickness Tis less than or equal to 0.8 mm. The first radial lip thickness Tis less than or equal to 0.7 mm.
