ABSTRACT OF THE DISCLOSURE A unitized oil seal assembly having a primary seal element including a casing element of annular form made from a relatively rigid material and having an at least partially elastomeric sealing lip body bonded thereto, and a single or one-piece wear sleeve and unitizing casing portion including a radial flange acting as an axially exterior protective element preventing relative axial movement of the associated primary seal in one direction. An axially extending wear sleeve portion has a cylindrical outer diameter surface facing toward and sealingly engaged with the seal band portion of the primary lip, and a second, unitizing or locking flange of reduced thickness and reduced diameter with respect to the protective flange which prevents axial removal of the primary seal unit in the other axial direction.
