ABSTRACT:
A unitary radial lip seal assembly to provide a fluid tight seal between a shaft and a housing bore through which the shaft extends includes an annular rigid retainer, a resilient body portion secured to the retainer and defining at least one sealing lip to seal against the rotatable shaft and a sleeve bearing member supported by said seal assembly outboard of the sealing lip. In one form the bearing member is rigidly connected to the retainer, in another, it is resiliently mounted to provide shaft vibration dampening. In the latter embodiment, the bearing member includes a radial wall urged into frictional engagement with a radial wall of the resilient body to restrict rotation of the bearing member.
