Rod seal K22 10x18x5,5 PU

The K22 sealing ring is a single-acting hydraulic gland seal for piston rods, commonly known as a "lip seal". The seal's cross-section is based on an asymmetric arrangement of two lips: the inner (dynamic) lip is shorter and faces the piston rod surface, while the outer (static) lip is longer and rests against the bottom of the housing groove. This design provides effective static and dynamic sealing during the reciprocating movement of the piston rod. The lip angle is 20°, and all edges of the seal are rounded and free of burrs in accordance with the manufacturer's specification. The seal is made of polyurethane PU9201 with a hardness of 92 Shore A. This material is characterised by abrasion resistance and good mechanical strength under typical operating conditions of hydraulic systems. The K22 ring is used to seal the piston rod of a hydraulic cylinder in construction machinery, forklifts, injection moulding machines, agricultural machinery, loading platforms and standard cylinders.
