Wiper XSWR03

Function:
Wipers are designed to keep dust, dirt, sand and others off the rod and the sealing and guiding elements, avoiding abrasive damage caused by external contamination.

Features:

  • The profile is designed with interference on the OD which provides a good static fit, preventing the entry of humidity and other contamination via the outside diameter.
  • Tight seat in the housing ensures that the wiper is held in place.
  • Prevention of corrosion in the seat due to the use of a retainer ring in hard plastics.
  • Not suitable for pressure from the trailing side.
  • For housing acc. to ISO 6195-1986 – Type B.

  • Reciprocation rods in hydraulic cylinders, plungers.
  • Max. pressure 0 bar, max. speed 4 m/s.
