China Uhs Type Hydraulic Piston Rod Polyurethane Seal

Description
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.
Technical data
Working pressure:≤40MPa;
Working temperature:-30~+100ºC;
Working medium:Hydraulic oil (mineral oil based);
Reciprocation speed:≤0.5m/s
Advantages
- Good pressure-adapted sealing effect
- Unaffected by high loads and deflections of the piston rod
- High resistance against extrusion.
- Lower friction in the low-pressure range compared with double-lipped versions.
- Excellent in static and dynamic sealing
-Low requirements on groove roughness
- Easy installation.
Applications
Light and medium load hydraulic reciprocated sealing system. Widely used at industries such as mobile machinery, light machinery, agricultural machinery, injection molding machinery, forklifts, cranes, automobiles, forestry machinery and mining machinery, etc. Favorable mechanical characteristics even under tough working conditions.
Materials
The USH seal ring can be made of NBR, FKM, PU according to the application.
Polyurethane is a material that has the elastic properties of rubber. The proportion in its composition (diisocyanate, polyol, chain extender) 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.
