DESCRIPTION:
Zurcon®Da24 is a double-acting thermoplastic polyurethane scraper for severe operating conditions and heavy attack of dirt. A new improved design available now in two different versions has been recently developed by Trelleborg Sealing Solutions to enhance the overall performances.
The special design of the inward-facing sealing lip contributes to an optimum contact pressure resulting in a very high scraper effect of the residual oil film thanks to the sharp, knife cut, scraping lip.
The outer scraper lip leans against the housing. This ensures an optimum sealing force and further it prevents the ingress of dirt and water across the groove bottom. also in case of high level of external contamination and dirt or rod eccentricity under side load the scraper effect remains stable. The improved design reduces the friction with less heat generated and a longer service life.
The new design of Da24 is now available in two versions: standard and venting. Da24 is produced in Zurcon®, the Trelleborg Sealing Solutions proprietary thermoplastic polyurethane material specially developed for sealing applications. This provides long service life under harsh working conditions and resistance against installation damage.
