ABSTRACT:
A shaft seal adapted to be inserted into the bore of a housing and around a shaft therein is disclosed, wherein an annular elastomeric sealing ring is molded to provide an annular sealing lip around the inner diameter thereof, and an annular groove extending inwardly from one surface thereof in an axial direction. A separate and removable spring ring in the groove expands the seal outwardly against the wall of the bore, and a garter spring in the groove compresses the sealing lip against the shaft. If desired, a reinforcing ring may also be positioned in the groove between the bottom thereof and an end of the spring ring.
