Pneumatic seal 16x20,5x4/3,4 A853 PU

Rod seal A853 for pneumatics, size 16×20,5×4/3,4 mm, made of polyurethane (PU). Used in pneumatic cylinders as a rod seal, it also works as a wiper: it removes dirt from the rod surface on the return stroke, which further protects the inside of the cylinder. Design features: rod seal profile for pneumatic applications, sealing lip with a wiping function, stable body for easy fitting in the groove, for reciprocating motion. Technical data: Inner diameter: 16 mm (≈ 0.63") Outer diameter: 20,5 mm (≈ 0.81") Total height: 4 mm (≈ 0.16") Working height: 3,4 mm (≈ 0.13") Material: PU 92 ShA Maximum pressure: 20 bar Speed: up to 1 m/s Material – polyurethane (PU): high resistance to abrasion and mechanical wear, good elasticity for effective sealing, resistant to compressed air and lubricating oils, developed especially for pneumatic applications.
