ABSTRACT:
A one-piece, reusable hub seal unit for heavy duty axles and the like. The unit includes a stiff but flexible casing covered with an elastomeric portion. The casing has a radial flange, a slightly axially inclined sleeve portion, and a purely axial portion ending in a free edge. The elastomeric covering is thin adjacent the free edge, gradually increases in thickness throughout the slightly inclined axial extent and finally contains a radial section covering the flange and having two or more sealing ribs. A cover holds the seal unit in place when it seals snugly in the counterbore. When the cover is removed, the seal may be removed by hand from the counterbore.
