Abstract: An apparatus is disclosed for monitoring characteristics of a fluid lubricant contained within a lubricant chamber formed in a wheel hub mounted for rotation about a stationary wheel axle. The apparatus includes an annular bearing spacer configured for mounting on the wheel axle between axially opposed inboard and outboard bearings, the annular bearing spacer forming an interior lubricant reservoir between an inner surface of the spacer and the wheel axle, a guide vane for directing lubricant from the lubricant chamber to the interior lubricant reservoir during rotation of the wheel hub assembly about the wheel axle, and a sensor operatively associated with the interior lubricant reservoir for determining a condition of the lubricant.

Abstract: A gasket assembly is disclosed for use between adjacent flange surfaces which includes a reusable annular base plate having an inner periphery and opposed upper and lower surfaces, and replaceable a spring energized sealing ring releasably retained within the inner periphery of the base plate and including a resilient spring element surrounded by a deformable jacket that extends beyond the upper and lower surfaces of the base plate to conform to surface irregularities in the flange surfaces upon compression of the gasket between the flange surfaces.

Abstract: A hub seal for installation on the wheel end of a heavy duty trailer or truck is disclosed which includes an annular casing, an elastomeric sealing ring supported within the annular casing and including an axially extending sealing lip, an annular sleeve mounted coaxial with the annular casing, the annular sleeve having an axially extending sealing surface, and a spring for biasing the axially extending sealing lip against the axially extending sealing surface such that a substantial portion of the sealing lip is in sealing engagement with the sealing surface over a substantial contact area.
