Wipers

Prevent contamination in the hydraulic system A hydraulic wiper or scraper prevents contamination of the hydraulic medium that could damage wear rings, seals and other components. Yimai Sealing Solutions offers a wide range of hydraulic scrapers and wipers. 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.

  • Wipers AS is the standard dust seal

    Wipers AS is the standard dust seal

    Space saving structure
    Simple, small installation groove
    Due to the use of metal pressing mode of installation, good stability in the groove
    When the bearing re-flows oil, the dust scraping lip can automatically open under lower pressure and discharge the dirty oil.
    Very wear resistant

  • Wipers A1

    Wipers A1

    The function of A1 type dustproof ring is to prevent dust, dirt, sand and metal chips from entering, through special design, prevent scratching, protect guide parts, prolong the working life of seals. The diameter of interference ensures that the upper seal is tightly packed into the groove, thus preventing the invasion of impurities and moisture. A1 type dustproof ring provides a closed chamber for the cylinder, without screws and brackets, without strict tolerances, and without metal plug-ins, preventing corrosion like metal skeleton dustproof ring may occur. Grooves also do not require strict tolerances.
