Trelleborg Sealing Solutions launches the Zurcon® Scraper DA24 Venting Version double-acting scraper. This is especially for severe operating conditions in fluid power applications such as hydraulic systems in off-road vehicles. Its unique venting design incorporates a pressure-relieving function to prevent system failure.
Off-road vehicles are a typical application for the Zurcon® Scraper DA24 Venting Version
Zurcon® Scraper DA24 Venting Version is based on the well established double-acting scraper DA24 which has proven effective in applications within aggressive environments for many years, especially where there is a high level of external contamination and dirt.
However, in some situations when there is pressure build-up behind the scraper, the scraper can be pushed out of the groove causing total sealing system failure. Zurcon® Scraper DA24 Venting Version has axial holes through the section which operate as pressure-relief valves, allowing oil to be released in the case of overpressure. With improved stability in the groove the Zurcon® Scraper DA24 Venting Version becomes one of the most efficient scrapers available on the market.
