Wipers

Scrapers or wipers are installed in the sealing configurations of hydraulic cylinders to scrape dirt, external particles, chips or moisture from the piston rods as they retract into the system. A hydraulic wiper or scraper prevents contamination of the hydraulic medium that could damage wear rings, seals and other components.

The selection of the shape and form of the wiper depends from several factors:

  • Function as a wiper only or as a wiper/seal
  • Dirtiness load in the external area of the system
  • Sliding speed
  • Space requirement in the design area
  • Open or closed installation space
  • Temperature range and/or medium
    (important for selection of material)
