Rotary Seal XSR03

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 for high pressures and low speeds, designed with interference on the OD which provides a good static fit in the groove.
  • Dynamic sealing on the ID.
  • Backup elements on the left and right side for maintaining the function also at large sealing gaps.
  • Excellent static and dynamic sealing performance.

Application

  • Slow moving shafts, pivoting movements, swivel or rotary joints.
  • Used as seal between two pressurized spaces.
  • Max. pressure 400 bar, max. speed 0.2 m/s.
