ABSTRACT:
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, an annular inner case, and a spring member, the inner case being 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. In an alternative embodiment, a leg portion of the outer case extends axially along the entire length of the seal assembly to protect the other components during installation. Also, a terminal end portion of the resilient layer extends between adjacent legs of the inner case and the outer case to provide a resilient cushion therebetween as the inner case moves axially relative to the outer cause, preventing undesirable contact therebetween.
