Piston Seal XSPS16MF (with spring)

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

Features:
  • Asymmetrical, single acting piston seal.
  • Long sealing lip compensates for radial inaccuracy or excentricity.
  • Useable for long stroke lengths.
  • Low break-away load after long standstills.
  • Seal design tends to “stick-slip” effect.
  • Spring-loaded lip seal. Clamping flange for fixing in the installation space.
  • We recommend more modern series for new designs.

Application

Reciprocating pistons in hydraulic and pneumatic cylinders.
Replacement for seal designs (leather seals etc.) used in old cylinders.
Max. pressure and max. speed depending on material.
