Rod Seal XSRS35A

Function:
Rod seals are designed to seal the pressurized hydraulic fluid against the atmosphere or between two pressurized spaces.

Features:
  • Asymmetrical, double acting compact rod seal, designed with interference on the OD which provides a good static fit in the groove.
  • Excellent static and dynamic sealing performance.
  • Excellent performance in low pressure conditions.
  • For rotary applications the interference on the OD has to be increased (better static fit to reduce the danger of the seal rotating in the housing), the preload has to be reduced (lower friction).
  • Up-dated design of XSRS35.

Application

  • Reciprocating rods in hydraulic cylinders, plungers.
  • Static and dynamic seals in hydraulic systems, replacement for O-Rings (no twisting or pumping), alternative design for composite rod seals (PTFE + O-Ring energizer).
  • Depending on material: max. pressure 400 bar, max. speed 0.4 m/s.

    • Seal housing recommendation
