190A2-57291 RING SEAL For HITACHI ZW310-5A QSM11-1

A ring seal, also known as a sealing ring, O-ring, or gasket ring, is a versatile sealing component used to prevent the leakage of fluids or gases between two connected surfaces. It is typically circular and made from materials such as rubber, silicone, or other elastomers, offering excellent flexibility, durability, and resistance to pressure, temperature, and chemical exposure. These seals can be used in both static applications, such as pipe joints, and dynamic applications, like hydraulic cylinders or rotating shafts. Ring seals are integral in industries such as automotive, aerospace, plumbing, and manufacturing, ensuring reliable performance in high-pressure and extreme operating conditions. Their simple design, ease of installation, and cost-effectiveness make them an essential component in modern engineering systems.

The sealing ring is a kind of annular seal with notch, which abuts against the inner hole wall of the stationary part by virtue of its elasticity after being pressed together. The seal ring is a kind of annular seal with notch. It is placed in the ring groove of the sleeve, and the sleeve rotates with the shaft. The seal ring abuts against the inner hole wall of the stationary part by virtue of the elasticity of the notch after being pressed together, which can play a sealing role. All contact surfaces need to be hardened and polished. Ring seals mainly include O-ring, U-ring, V-ring and Y-ring, which have different characteristics and applicable scenarios.
