摘要
A radial shaft seal assembly is provided including an inner wear sleeve having a cylindrical wall with a bore sized for tight receipt of a shaft therethrough and an exposed cylindrical outer surface. The inner wear sleeve includes an oil side flange and an air side flange extending radially outwardly from the inner wall in axially spaced relation from one another. The assembly includes an outer case having cylindrical outer wall configured for receipt in a housing. An elastomeric body is fixed to the outer case. The elastomeric body includes an annular serpentine portion extending radially inwardly from the outer wall to a radially innermost end. A main seal lip extends from the innermost end of the annular serpentine portion into sealed contact with the oil side flange. A dust lip extends from the innermost end of the annular serpentine portion into sealed contact with the air side flange.
