A855 pneumatic cushioning seals
Pneumatic cushioning seal A855 is designed to be used for the cushioning piston in pneumatic cylinders to slow the cylinder down after fast movements.
It offers excellent cushioning consistency due to automatic centring, high wear resistance, long service life, easy installation, very low dynamic and static friction, and is suitable for both oiled and oil-free working conditions (please note that the seal should be lubricated on assembly).
A855 is manufactured with high specification special 92 Shore ALP PU compound as a standadrd, and is available in a wide range of sizes.
