IMPROVED BEARING ISOLATOR

摘要

A combination labyrinth and contact seal assembly for sealing about a rotary shaft (10). The assembly includes a rotor element (13) having an extension (13a) which covers a substantial axial portion of the shaft (10) against which the contact seal inserted in the stator (14) rotates. The sealing insert (21) in the stator (14) is capable of being replaced as the sealing material wears out. The exterior surface of the rotor-sleeve or axial elongation (13a) of the rotor (13) is of precisely contoured parallel circular asperities or disk like profiles on the sleeve surface against which the seal insert (21) contacts.
