Abstract
A seal assembly has an inner wear sleeve with an axially extending tubular body. A flange extends radially outwardly from the body. An outer seal component has an axially extending tubular outer wall with a flange extending radially inwardly therefrom to support at least one dynamic seal lip in sealing engagement with the inner sleeve body. The outer seal component includes an annular retention lip disposed axially outwardly of the wear sleeve flange. The retention lip extends radially inwardly of a radially outer edge of the flange and is deflectable in an axial direction to enable the flange of the wear sleeve to be forced axially thereby during assembly, whereupon the retention flange returns to its non-deflected position to inhibit removal of the wear sleeve in the reverse axial direction. The annular retention flange has at least one axially extending debris expulsion slot for the escapement of debris.
