China High Polymer Wear-Resisting PU Seal Ring

Description
The hydraulic symmetrical 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.
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.
Technical data
Working pressure:≤40MPa;
Working temperature:-30~+100ºC;
Working medium:Hydraulic oil (mineral oil based);
Reciprocation speed:≤0.5m/s
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
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.

Cases:

Morgan seals is a company who was established by Guangzhou Mechanical Engineering Research Institute Co., Ltd. (51% share, hereinafter to be referred as GMERI established in 1959) and Morgan Construction Co., Worcester, MA, U. S. A. (49%, hereinafter to be referred as Morgan, Worcester established in 1888) in 2006. Now she is a professional manufacturer for rubber sealing products. Combined the rich seals research and production experience of GMERI with the advanced technology and administration of Morgan, Worcester, our company has gained a good name from her cusomers all over the world, such as the Siemens Primetals, Baosteels .... The largest PU plastic seal we produced is the sealing ring for Three Gorges Hydroelectric Power Station water-turbine generator(OD is 13000mm).

Guangzhou Morgan Seals has the biggest vulcanizing machine(4000T) and different kinds of seal moulds. So for the non-standard hydraulic seals, please feel free to contact with us. The following is the the picture Morgan Production Line and Warehouse:
