The High-Performance Shaft Seal

Constructional Features

Universal shaft seal ringsare produced without metal housing and do basically consist of three elements:
  • fabric-reinforced Elastomer to secure the seal rings against the casing bore.
  • seal lips made from a homogeneous Elastomermixture with addition of PTFE (minor friction!)
  • stainless steel garter spring
Universal shaft seal rings are available in various
types, in split and endless version.


Universal shaft seal rings are generally used in the
engine construction, however, mainly with heavy equipment and shipbuilding (e.g. rolling mill, power transmission, propeller shaft, water turbine etc.).

In addition to the above, they are used where shaft seal rings in a metal housing may not be applied.
