Rod Seal XSRS02C

Function:
Rod seals are designed to seal the pressurized hydraulic fluid against the atmosphere, preventing leakage and pollution of the environment.

Features:

  • Asymmetrical, single acting rod seal with anti extrusion ring, designed with interference on the OD which provides a good static fit in the groove.
  • Primary seal in tandem arrangements of heavy duty applications.
  • Thin and flexible static lip to enable pressure relief, built up between primary and secondary seal.
  • Replacement for the primary O-Ring energised rod seals in tandem arrangements.
  • Not recommended as single/main seal in sealing systems.
  • Suitable for high pressure peaks at about 700 bar.
  • Radial grooves on the sealing lip recommended to reduce any risk of „blow-by“.
  • Useable for long stroke lengths.

  • Primary seal in tandem arrangements in hydraulic cylinders for construction machines,
    draulic excavators or earthmoving equippment.
  • Max. regular pressure 400 bar (peaks up to 700bar), max. speed 1 m/s, depending on material selection.
