Rotary Seal XSOS03

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.
  • Solid version of XSOS01 profile. For version in PTFE or similar housing must be axially accessible.
  • Tension spring for increasing the bonding force.
  • Not suitable for high pressure from the trailing side.

Pumps, electric motors, swiveling cylinders, etc.
Max. pressure 0.5 bar, max. speed: PU 5 m/s; NBR 10m/s; FPM 25m/s.
