The utility model relates to an axial-acting elastic rubber seal ring, which is used for a rotary shaft non-pressure seal. The sealing lip has better mobility and adaptability, can compensate for large tolerance and angle deviation, can prevent internal grease or oil leakage, can also prevent external splash water or dust invasion.

1.The working life of dynamic pressure seal is 5 ~ 10 times higher than that of conventional rubber seal products, and can be up to tens of times.
2. The friction between the sealing ring device and the moving parts shall be small and the friction coefficient shall be stable.
3.The sealing strip is a product that seals something so that it is not easy to open, and plays the role of shock absorption, waterproof, sound insulation, heat insulation, dust prevention, fixation, etc. Sealing strips are made of rubber, paper, metal, plastic and other materials.
4. Simple structure, convenient use and maintenance, so that the sealing ring has a longer service life.
1. Quick response in 12 hours
2.Reliable imported raw material
3.Strict analysis and testings on raw material before production
4. Assistance from first idea through prototype
5.First prototype inspection after mould and before volume production
6.Quick delivery of prototypes or production needs
7.Design assistance and parts consolidation
8.In-house mold design (Insert, polyurethane, urethane molding)
9.In-house formulations to provide the best possible urethane for your application
10. Low-cost tooling
11.Over 20 years of in-house experience
12.Reliable after-sales service and support
1. Put the sponge cover on the split ends, and evenly apply about 0.5mm of grease on the inner circumference.
2. After removing the sponge sheath, apply a special adhesive to the section mold under the split.
3.The butt split surface is pressed tightly and held for 10 to 20 seconds.
