Scrapers or Wipers are installed in the sealing configurations of hydraulic cylinders to scrape dirt, foreign 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.
Trelleborg Sealing Solutions offers a wide range of hydraulic scrapers and wipers in metal, elastomer, Turcon® Polytetrafluoroethylene (PTFE) based material or Zurcon® polyurethane. These include the Turcon® Excluder®, which is the Trelleborg Sealing Solutions proprietary design of double-acting hydraulic scraper.
Specially engineered for hydraulic cylinder applications, Turcon® and Zurcon® materials demonstrate excellent low-friction properties providing exceptional resistance to wear.
