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.
Joint d'étanchéité lubrifiant (10) destiné à être installé dans un espace libre annulaire situé entre un arbre (12) et le logement qui l'entoure (14), et comprenant des boîtiers interne (16) et externe (18) pouvant être fixés par pression sur l'arbre (12) et sur le logement (14). Une butée antichoc annulaire (29) est disposée entre les surfaces de contact des boîtiers (16, 18) pour limiter leur mouvement télescopique excessif pendant l'installation. La butée antichoc (29) se compose d'un matériau fusible, de sorte que, durant une période de rodage initiale, la chaleur de frottement fait fondre une partie du matériau de la butée afin de rapidement constituer un joint d'étanchéité à coefficient de frottement réduit.
