WR2 is a double acting dirt wiper consisting of a scraper part of low friction material, energized by a rubber O-ring. Wiper WR2 is pressure activated. This wiper can be used in a great variety of environments. Our low friction materials are compatible with almost all media. It is a medium duty dirt wiper recommended for indoor systems. It is likely to be used in combination with our low friction bearing rings and sealing system. For long strokes a pressure release hole should be included between scraper and last seal.
Max. velocity is 15m/s also depending on the material used.
