Premium o ring manufacturer and supplier

O rings manufacturer and supplier in China? We can design the suitable spring energized seals for your application. Our oil seals have TC, TB, SC, DC, TCV and so on. Looking forward to supply the best seals for you.(O Ring Manufacturers & Hydraulic Oil Seal Manufacturers). DMS SEALS, the seals manufacturer, was founded in 2008. DMS started by manufacturing filled PTFE seals, including bronze filled PTFE, carbon filled PTFE, graphite PTFE, MoS2 filled PTFE, and glass filled PTFE. We now also produce O-rings made of NBR, FKM, silicone, EPDM, FFKM. See more details on seals manufacturer.

The spring seal produced by DMS SEALS is perfect for being applied to extremely high-speed, very low-speed equipment with micro piston strokes and other special operating conditions. It can be used with rotary seals and maintains good sealing performance in violent shake and vibration motion environments. At the same time, our seals are extremely adaptable to a wide range of working media. It is resistant to a wide range of chemicals except for soluble alkali metals, high-temperature fluorine and chlorine trifluoride. Therefore, it works well with liquids such as oils and water with high and low temperature.

Sealing performance over conventional O-rings is achieved by reducing particle generation, extending seal life and minimizing replacement time during preventive maintenance. Compared to traditional O-rings, this seal effectively reduces the number of dust particles generated during operation and extends the life of the machine with bonded seals installed. The seal has a working diameter range of 6.5 to 60.58mm.

Since the scraper seal is made of the special material, PTFE, it has an impurity immersion function. Therefore, when combined with the piston rod seal and the metal bushing, it can prevent damage to the piston rod and prevent the accumulation of oil pressure. It has a diameter range of 3-1600mm and a temperature range of -30°C + 200°C. The wiper scraper seal can operate at speeds of up to 5 m/s. It has high wear resistance, tear resistance, low-temperature resistance and good strength. Our wiper seals can be used in combination with piston seals and anti-wear rings to prevent oil in the cylinder from being mixed with foreign matter, which causes damage to the working seal. It is especially suitable for piston rods with a large diameter. Moreover, it has a wide range of applications, such as agricultural machinery, injection moulding machines, forklifts, cranes and so on.

Influence of flange form: Different flange forms require different gaskets. Smooth-faced flanges are generally only used for low pressure, with soft thin gaskets; under high pressure, if the strength of the flange is sufficient, smooth-faced flanges can also be used, but thick soft gaskets should be used, or inner belt reinforcement should be used. Wound gasket for ring or reinforcement ring. In this case, metal gaskets are also not suitable, because the required pressing force is too large, resulting in large deformation of the bolts, making the flange difficult to seal. If a metal gasket is to be used, the smooth surface should be reduced to reduce the contact area with the gasket. In this way, under the condition of the same bolt tension, the compressive stress of the reduced narrow smooth surface will increase.

Construction machinery, also known as construction machinery, is mainly used for mechanical and electrical equipment for the construction, renovation and maintenance of various buildings. Widely distributed in industrial and civil construction, urban construction, national defense construction projects, transportation construction, mining and other raw material industrial construction and production, agriculture, forestry and water conservancy construction, sanitation and environmental protection industries. It contains a wide range of types, such as excavators, loaders, cranes, pump trucks, pile drivers, hydraulic breakers, pavers, graders, rock drills, etc.

Support and positioning The piston and piston rod are radially supported and positioned in the cylinder barrel. Isolate the two pairs of motion pairs of piston and cylinder, piston rod and guide sleeve to prevent direct scratches, abrasions and strains between the motion pairs. Especially when the motion pairs are all steel parts, they must be isolated, otherwise they will be easily strained. The guide belt also has an important role to reduce the friction and friction work between the moving parts, reduce the ineffective work and heat. Vibration absorption and noise reduction Reduce system vibration and noise. It is mainly filled with tetrafluoroethylene and phenolic cloth, and there are also a very small amount of polyoxymethylene, nylon and soft metal. See more details on
