ABSTRACT:
An annular lubricant seal assembly for an annular lubricant seal assembly for providing a seal between a shaft extending through a bore formed in a housing and the housing, wherein the shaft and the housing are rotatable relative to one another. The seal assembly includes an annular outer case, which is press fit into the bore, and an annular inner case, which is mounted on the shaft. Portions of the outer case extend adjacent to, but are spaced apart from portions of the inner case. An elastomeric seal member is secured to the outer case. Flexible lips formed on the seal member engage both axially and radially extending portions of the inner case disposed adjacent to the outer case. As a result, the seal member is capable of providing a secure seal against the shaft, even when the shaft moves axially or radially relative to the housing during use.
