Wiper Ring XSWR02C

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 an additional sealing lip on the OD which provides a good static fit, preventing the entry of humidity and other contamination via the outside diameter.
  • Sharp sealing lip for wiping in extreme conditions (minig industry, ice,...).
  • Commonly made out of hard materials such as hard grade PU.

Application

  • Reciprocation rods in hydraulic cylinders, plungers.
  • Extreme working conditions in mining industry or earth moving devices.
  • Max. pressure 0 bar, max. speed 4 m/s.
