ABSTRACT:
A system for providing a seal between a housing and a shaft is formed of at least two ring members connected to each other by relative diametrical expansion with reduced or eliminated axial resilient deformation. The ring members may be held together by an annular protrusion located within a recess. To eliminate play between the protrusion and the recess, the device may be assembled by heating the recess and inserting the protrusion into the recess while the recess is expanded. The improved system can be accurately assembled, with the ring members located very close to each other. The system has improved oil retention and water exclusion properties.
