Rotary Seal XSOS02

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:
  • 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.
  • Additional dust lip for preventing the sealing lip of dirt.
  • 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.

Application

  • Pumps, electric motors, swiveling cylinders, etc.
  • Max. pressure 0,5 bar, max. speed: PU/POM 5 m/s; NBR/POM 10m/s; FPM/PTFE 25m/s.
