Rod Seal XSRS17D

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, designed with interference on the OD which provides a good static fit in the groove.
  • Special design for small cross sections where lips would be too thin.
  • Secundary lip for stabilising at large seal heights and reducing the residual oil film.
  • Excellent static and dynamic sealing performance.
  • Excellent performance over all pressure ranges.
  • Used for short pulsating strokes.
  • No reverse leakage when changing direction.
  • Recommended for positioning or holding under pressure.
  • Particularly suitable for high viscosity media.

Application

  • Reciprocating pistons/rods in hydraulic cylinders, push rods, fittings etc.
  • Switching or clamping functions.
  • Replacement for rubber fabric seals.
  • Max. pressure 400 bar, max. speed 0.5 m/s for all HPU types.
  • Max. pressure 400 bar, max. speed 0.7 m/s for HPU94 GM.
  • Max. pressure 160 bar, max. speed 0.5 m/s for all elastomer types.
