A853 Pneumatic rod seals/wipers
A853 is a single acting combined seal/wiper designed to be used in rod applications of pneumatic cylinders, performing simultaneously sealing and wiping functions. It is manufactured from high specification PU92 or NBR90 compounds as a standard.
A853 pneumatic rod seal/wiper offers excellent sealing performance even in very small assembly conditions. It also offers high wear resistance, long service life, easy installation, resistance to very harsh working conditions because of its robust profile design, very low dynamic and static friction and smooth running due to lip geometry and is suitable for oiled or oil-free working conditions (note that the seal should be lubricated on assembly).
A853 can be used safely for compact and small pneumatic cylinders.
