Wipers / Scrapers
Scrapers or wipers scrape dirt, foreign particles, chips and moisture from the rod as it is retracted into the cylinder. With the help of scrapers, contamination of the medium is thus prevented, which also immediately means that damage to the bearing belts, seals and other parts is prevented.
AST High-Performance Wipers
Advanced Sealing Technology’s scrapers are available in a variety of materials including metals, elastomers and polyurethane. These materials ensure that the wipers show excellent low frictional resistance, which in turn results in perfect wear resistance.
