ABSTRACT:
A two-part, separable, semi-unitized shaft seal for sealing between a housing bore and a relatively rotatable shaft extending through the bore and comprising a metal wear sleeve member and a sealing member assembled onto the wear sleeve member for transportation, shipping and installation of the seal as a unitized seal. However, when the housing and shaft are disassembled, one of the two seal parts remains with the housing and the other part remains with the shaft, whereby each part can be examined and replaced, if necessary, without discarding the entire seal. One seal part press-fits onto one of the housing and shaft and the other seal part forms an elastomeric interference fit on the other of the housing and the shaft.
