Function

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.

 

Features

  • Asymmetrical, double acting rotary seal, designed with interference on the OD which provides a good static fit in the groove.
  • Additional sealing edge on the OD for better static sealing.
  • Dynamic sealing on the ID.
  • Excellent static and dynamic sealing performance.
  • Low friction.

Slow moving shafts, pivoting movements, revolving distributors, swivel joints.

Universal rotary seal for minor work loads.
