<p>A lubricant seal assembly (10) adapted for installation in an annular clearance space between a shaft (12) and a surrounding housing (14). The assembly (10) includes inner (16) and outer case (18) members that can be press fit on the shaft (12) and housing (14). An annular bumper element (29) is arranged between confronting surfaces of the case members (16, 18) to limit excessive telescopic motion of the members (16, 18) during the installation process. The bumper element (29) is formed of a fusible material, such that during an initial break-in period frictional heat melts some of the bumper material to quickly produce a low friction seal assembly.</p> |
