The O-ring of DMS SEALS is often used in hydraulic and pneumatic transmission systems and has wide applications. It can be used for both static and reciprocating seals. Moreover, it can also be used in rotary sealing systems. The O-ring can be installed in a groove with a rectangular cross section on the outer or inner circle, achieving a good sealing effect. It has many advantages compared with other types of sealing rings. Its compact structure makes it easy to assemble and disassemble. Moreover, its dynamic frictional resistance is relatively small, and a single piece of O-ring can achieve sealing performance in both directions.
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.
Our piston seals are designed to provide excellent leak control. We guarantee that it can perfectly meet the user’s requirements for low friction, compactness, precise configuration and simple installation. It is designed for fluid power applications. It is made of compound materials with high performance, which guarantees excellent wear resistance and excellent extrusion resistance for the seal. It is designed to be suitable for almost all fluid media and is highly resistant to oxidation and corrosion. It has excellent dynamic and static sealing performance and can even work under dusty industrial environments. Moreover, it has strong adaptability to various working conditions and can adapt to a fast, high-pressure working environment. At the same time, it has unparalleled performance in extreme temperature environments.
Gasket sealing mechanism: The function of the gasket is caused by the blocking effect on the internal medium formed by the contact pressure of the sealing material on the joint surface and the elastic restoring force to the external tightening force. Classification and structure of gaskets: Gaskets are divided into three categories: non-metallic gaskets, non-metallic and metal combined gaskets and metal gaskets. The common materials are rubber, leather, asbestos board, cork, PTFE, tinplate, steel, aluminum, copper and stainless steel.
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.
Supplied in rolls or open loops. The open ring can be directly installed and used, but it must be cut when the roll is used, and the cutting length must be calculated in advance: there can only be one opening, the opening form is an oblique 45° opening, and the opening distance is about 3-15mm, or the diameter of the guide ring 3-5% of . Under normal circumstances, the openings are oblique openings. Straight openings or zigzag openings are rare and have specific uses and purposes. There are two purposes for the opening. The first is to facilitate installation. If it is not opened, it is an integral ring, which is difficult to install or impossible to install, so it must be opened. Secondly, the opening and a certain opening distance are reserved to facilitate the automatic coordination of volume changes. Otherwise, the movement may be stuck or the moving parts may be pulled due to the excessive expansion of the guide belt under certain conditions. Coiled ones are relatively cheap, and the same coil can be used to make guide rings of different sizes. Read extra info at https://www.dmsseals.com/.
