Top o ring manufacturer? 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. Read even more info at custom o ring manufacturer.
The radial force of our rotary seals on the shaft and the distribution is very reasonable. It can achieve the optimal “critical oil film thickness” working condition and always maintain critical lubrication. We guarantee that our rotary seal can help the machine get the sharpest “peak” pressure distribution with the least radial force, providing the best sealing effect. The bearing seal is designed by DMS SEALS to isolate the moving metal part, guiding the piston and piston rod of the hydraulic cylinder to move in a certain direction and it can help withstand lateral loads. It helps prevent any direct contact between the piston metal and the cylinder metal and prevents strain and seal damage on the inner surface of the cylinder.
It can maintain stable performance after prolonged exposure to various corrosive compounds. Due to its lack of polarity, low unsaturation, and high chemical stability, our gasket has high resistance to various polar chemicals such as alcohols, acids (acetic acid, hydrochloric acid, etc.), strong base (sodium hydroxide, oxidant, hydrogen peroxide), detergents, animal and vegetable oils, ketones and certain esters. It is designed to have excellent aging resistance and excellent resistance to compression set and compression stress relaxation. Therefore, our gasket has significant advantages over other conventional gaskets. Its excellent materials and manufacturing process enables it to achieve effective sealing when exposed to corrosive chemicals, friction, high temperatures or very low temperatures. At the same time, it is easy to install and has industry-leading creep resistance, which saves users a lot of time and cost and increases productivity.
Scraper seals are also known as wiper seals. The scraper sealof DMS SEALS can effectively prevent various forms of contamination that cause a hydraulic system failure. It can be mounted on the outside of the piston rod seal of the hydraulic cylinder to protect the hydraulic cylinder from dirt, dust and moisture. It can well protect the hydraulic cylinder from environmental pollution and effectively prevent damage to the hydraulic cylinder parts, causing the system to malfunction. DMS offers a wide range of wiper seals for different hydraulic systems with different characteristics, specifications and combinations.
The selection principle of the gasket: according to the working pressure, working temperature, the corrosiveness of the sealing medium and the form of the sealing surface. Temperature influence: In normal temperature and low pressure, use non-metallic soft honey gasket; in medium pressure and high temperature, choose metal and non-metal combination gasket or metal gasket; when temperature and pressure fluctuate greatly, choose good elasticity or self-tightening type Gaskets; in low temperature, corrosive media or vacuum conditions, gaskets with special properties should be considered.
Because the system pressure is high, the temperature is high, and the wear is particularly serious, the seal is required to have good wear resistance. Low coefficient of friction: For construction machinery such as excavators and pump trucks, the hydraulic system pressure is high, the cylinder action speed is fast, and the wear of the seal is particularly serious. Therefore, the friction coefficient of the seal must be low, so that the seal has good wear resistance and suitable life.
The guide belt is a belt-shaped member that guides the moving parts. Its main function is to guide. In order to realize the function of guidance, it must support the guided member, and guide and correct its motion trajectory. In order to realize the guiding function well, it also requires isolation, shock absorption and noise reduction of the guiding parts. Guide belts are mainly used in oil cylinders and cylinders. Due to their excellent performance, they are also widely used in other motion mechanisms. See even more info at https://www.dmsseals.com/.
