Axial shaft seal in casing boring has inner part with outward facing annular washer of polymer material

摘要

The axial shaft seal is fitted in a boring in a casing in which an inner part (4) fixed to the shaft rotates. The inner part has an outward-facing annular washer (10) made of a polymer material. This washer lies against a counter-ring (14) on the outer part (20) to form the seal. The inner part (4) has a metal reinforcing ring (7) in an elastomer cladding (8).
