Abstract
A unitized seal includes a unitizing joint which is remotely spaced from a seal lip. The seal requires only two stampings with one elastomeric element bonded to one of the stampings. The remaining stamping forms a one piece wear sleeve having a first section with a wear surface which is engaged by a seal lip formed on the elastomeric element to provide a seal. A second section of this stamping extends angularly away from the wear surface and includes a terminal end which cooperates with the elastomeric element bearing stamping to form the unitizing joint.
