Rod Seal XSRS05A

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

Features:
  • Asymmetrical, single acting rod seal for pneumatic applications, designed with interference on the OD which provides a good static fit in the groove.
  • Special designed sealing lip to retain the lubrication film and prevent dry running.
  • Excellent static and dynamic sealing performance.
  • Useable for long stroke lengths.
  • Negligible tendency to “stick-slip”, small break-away loads after long standstill.

Application

  • Reciprocating rods in hydraulic cylinders, plungers, push rods, fittings, etc.
  • Switching or clamping functions.
  • Max. pressure 700 bar, max. speed 0.5 m/s.
