Abstract
A hub seal for installation on the wheel end of a heavy duty trailer or truck is disclosed which includes an annular casing defining a radially outer circumferential canal, a thrust ring defined by a ring of polymeric material disposed within the circumferential canal, and an annular sleeve mounted coaxial with the annular casing. The annular sleeve includes a deflector ring configured to mechanically remove at least a portion of the thrust ring upon relative rotation of the casing and sleeve to create a minimal running clearance between the deflector ring and the thrust ring. A method of fabricating a hub seal having a machinable thrust ring is also disclosed.
