Abstract
A bearing seal includes a seal case, a sleeve, and a thrust bumper that is disposed between the seal case and the sleeve and that is composed of a material that is at least 90% polytetrafluoroethylene by weight. The thrust bumper has an initial axial thickness that defines a spacing between the seal case and the sleeve when the seal case and the sleeve are compressed together during assembly of the bearing seal. The thrust bumper has a modified axial thickness less than the initial axial thickness after a break-in phase of the bearing seal.
