The O-ring is a kind of rubber ring with a circular cross-section. Because its cross-section is O-shaped, it is called an O-ring. It is the most widely used one in hydraulic and pneumatic transmission systems.
The O Ring is an extruded seal. The basic working principle of the extruded seal is to rely on the elastic deformation of the seal to cause contact pressure on the sealing contact surface.
Rubber has many uses in many fields. Whether it is in industry or in life, we can see rubber products everywhere. Just in order to fully understand the use of rubber, it is necessary to carefully classify the use of rubber.
Oil seal is a general term for products that function as a sealing system, which mainly include O-rings, oil seals, PTFE oil seals, dust rings, etc.
Rubber sealing rings are generally "Ο"-type rubber parts, and the cross-section is mostly circular. Compared with the skeleton oil (water) seal, the structure is simple, neither skeleton nor self-tightening spring, relying on the flexibility and elasticity of the rubber itself Seal it up.
O-ring is a kind of non-metallic gasket, which belongs to static seal, a common rubber ring with a circular cross-section. Similarly, O-rings are the most widely used seals in hydraulic and pneumatic systems.
