Piston Seal XSPS17B

Function:
Compact piston seal set, designed to seal the hydraulic fluid between
two pressurized spaces, preventing the flow of the fluid to the other side
and transforming the pressure force into the movement.

Features:
  • Double acting piston seal, designed with interference on the ID
    which provides a good static fit in the groove.
  • Consisting of one sealing and two guiding/back-up elements.
  • Two sealing edges on the OD for improved media separation.
  • Useable for short and long stroke lengths.
  • Good dynamic and static sealing performance.
  • High frictional force.

Application

  • Reciprocating pistons in hydraulic cylinders.
  • Universal piston seal for double-acting cylinders.
  • Max. pressure 400 bar, max. speed 0.5 m/s.
