Special Features: Double acting wiper/scraper AF-485 is used in hydraulic cylinders to wipe the inco- ming piston rod clean of dirt, water etc. Var- ious material combinations guarantee a high functional security and service life over the entire velocity range even with low friction, and it can also be used various temp eratures and media. . Two part composition consisting of wiper/scraper seal and O-ring A good wiper/scraper, because it also wipe away sticky media due to sharp lip and strong interfere- nce fit of the piston rod. Very good internal wiper/scraper performance for residual oil film that accumulates on the piston rod shall be removed Outstanding shear strength characteristics, without stick slip effect Good wear resistance, long life Wide temperature range and chemical resistance depending on O-ring material Available for all piston rods diameters up to app- rox. 2500 mm. AF-485 180 Double Acting Wiper Material: PTFE-Compound and PEHD Velocity: reciprocating to 15 m/s Temperature : -40 to + 200 °C, PEHD limit in Temp
