ABSTRACT:
A seal assembly for use in providing a dynamic fluid seal between a relatively rotating housing and shaft. The seal assembly eliminates the need for either a fixed internal thrust bearing or seal assembly contact with an adjacent inner bearing race. The seal assembly includes a spacer which provides an axial gap between a sleeve and seal support during installation. The spacer transmits the axial shaft installation load through the seal assembly into the housing. Once the seal assembly is installed, the spacer is removed, whereby the gap between the sleeve and seal support eliminates heat due to contact friction and reduces seal degradation.
