Zurcon® Scraper DA24 is a double-acting scraper made of Trelleborg Sealing Solutions proprietary polyurethane. The Venting Version is a unique seal that incorporates pressure-relief through axial holes to prevent system failure. This allows oil to be released through the seals outer lip when pressure builds up. A trimmed inner sealing lip gives optimum contact pressure meaning there is no residual oil film, while a robust outer scraper lip gives high contact force on the rod. This prevents penetration of moisture, dirt and impurities.
The seal gives excellent scraping performance and superior protection against ingress of external media. Advanced friction characteristics mean that there is limited heat generation and Zurcon® Scraper DA24 Venting Version gives extended service life. Effective against side loads, the seal is ideal in severe operating conditions with typical applications in construction machinery, mobile hydraulics, forestry machinery and telescopic cylinders.
