Mining Seal XSP50A

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 elastic sealing element and two back-up elements.
  • Two sealing edges on the OD for improved media separation.
  • Useable for short and long stroke lengths.
  • Good static and dynamic sealing performance.
  • High frictional force.

  • Reciprocating pistons in hydraulic cylinders.
  • Universal piston seals for double-acting cylinders.
  • Dynamic: Max. pressure 400 bar, max. speed 0.5 m/s.
  • Static: Max. pressure 1,500 bar, max. speed 0.2 m/s.*


*) for static application the preload should be increased to 13-15% instead of 10% dynamic.
