How to select the economical and effective rubber seals - O type sealing ring

The O-ring is a circular cross section of the rubber ring, because of its cross section is O, it is called the o-ring. Is one of the most widely used in hydraulic and pneumatic transmission systems. Usually in Taiwan enterprises, Japanese companies called oring.

O type sealing ring is a circular ring rubber seal ring. Mainly used for mechanical components under static conditions prevent the leakage of liquid and gaseous media. In some cases. O sealing ring can used to make axial reciprocating motion and low speed rotary motion of the dynamic sealing element. According to the different conditions, were chosen different materials and adapt.

O-ring is usually used to try to use a large section of the O ring. In case the same clearance. O-ring is squeezed into the interstitial volume should be less than the maximum permissible value of the squeeze.

For different kinds of stationary seal or seals for dynamic application occasions and the O-ring for designers to provide an effective and economical sealing element. O-ring is a bidirectional sealing element. When installing the initial radial or axial compression, given its initial O-ring sealing ability. The seal force generated by the system pressure and the initial sealing force synthesis, which increases with the increase of the pressure of the system. O-ring in static sealing occasions, display a prominent role. However, in appropriate cases in the dynamic, O-rings are commonly used, but it is the speed and pressure at the seal of the limit.
