Special Features: Double acting wiper/scraper AF-487 is used in hydraulic cylinders to wipe of the incoming piston rod clean,dirt ,water etc. It is also minimises the thickness of the oil film on the outgoing piston rod. Various material combinations guarantee a high functional security and service life over the entire velocity range, and is also giving a low friction, manage high and low temperatures and lot of different fluids. Two part composition consisting of wi- per/scraper seal and O-ring A good wiper/scraper, because it also wipes away sticky media due to sharp lip and strong interference fit of the piston rod. Very good internal wiper/scraper performance for removing oil film that accumulates on the pis- ton rod shall be removed Outstanding shear strength characteristics, wit- hout stick slip effect Good wear resistance, long life Wide temperature range and chemical resistan- ce depending on O-ring material Available for all piston rods diameters up to app- rox. 2500 mm. AF-487 185 Double Acting Wiper Material: PTFE-Compound and PEHD Velocity: reciprocating to 15 m/s Temperature : -40 to + 200 °C, PEHD limit in Temp
