The wiper type AS 02 equipped with two sealing edges is a double-acting seal. It consists of a PTFE profile ring and an O-ring as a preload element. The wiper function is taken over by the PTFE profile ring. The seal lip of the profile ring wipes off impurities from the retracting piston rod.
The inner lip reduces the grease layer thickness on the extending piston rod. These wipers are suitable for use with mineral oil-based hydraulic liquids, environment-friendly bio-oils and water and even with flame-resistant hydraulic liquids and air. The wipers provide very good gliding behavior and stick-slip free running, good dry-running properties and high wear resistance.
