Abstract
A unitized radial lip seal assembly includes an outer annular case and an inner annular wear sleeve loosely interlocked by flanges or walls formed at the axial ends of the wear sleeve. After initial installation of the unitized assembly within a housing, the wear sleeve can be axially shifted a slight distance to provide a slight axial separation of the wear sleeve from the annular case. Two separate lip seal elements are mounted to the outer annular case and protected from damage during shipping and installation by abutting surfaces of the case and wear sleeve.
