Abstract
A seal is provided for sealing a hollow shaft, where the hollow shaft has an inner surface that may be uneven due to shot peening. The seal includes an axially extending ring section having a first end, a second end, an inner surface, and a disk section disposed substantially perpendicular to the ring section inner surface between the ring section first and second ends. The seal conforms to the shaft inner surface to stop oil leakage.
