Rotary seals are designed to seal the pressurized hydraulic fluid against the atmosphere, preventing leakage and pollution of the environment or to transfer liquids and/or gases from a stationary part into or out of rotating machinery.


  •   The profile is designed with interference on the OD which provides a good static fit, preventing the entry of humidity and other contamination via the outside diameter.
  •   Tight seat in the housing and an additional retainer ring in hard plastic or Aluminium/Steel ensures that the seal is held in place .
  •   Tension spring for increasing the bonding force.
  •   Not suitable for high pressure from the trailing side.


Pumps, electric motors, swiveling cylinders, etc.
