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 and a sealing member assembled onto the wear sleeve for shipment and installation of the seal as a unitized seal. However, when the housing and shaft are disassembled, the sealing member remains with the housing and the wear sleeve remains with the shaft, whereby each part can be examined and separately replaced, if necessary, without discarding the entire seal. The wear sleeve pressfits onto the shaft and the sealing member forms an elastomeric interference fit in the housing bore.
