The UHS profile hydraulic polyurethane seals can be used both as a piston and rod seal due to their geometry. They are so to speak, a universal solution without a specific design of the sealing lip. Light and medium load hydraulic reciprocated sealing system. Widely used at industries such as mobile machinery, light machinery, agricultural machinery, injection moulding machinery, forklifts, cranes, automobiles, forestry machinery and mining machinery, etc. Favourable mechanical characteristics even under tough working conditions. Polyurethane is a material that has the elastic properties of rubber. The proportion in its composition is determined by its properties. This material is characterized by a strong mechanical resistance, good wear resistance, high elastic modulus, good flexibility and a very good ozone and oxidation resistance.
