Technical data of O-ring seal

O-shaped sealing ring is a rubber ring with a circular cross-section. Because of its o-shaped cross-section, it is called an o-shaped sealing ring. It is the most widely used one in hydraulic and pneumatic transmission systems. It is usually called oring in Taiwanese and Japanese companies.

   O-shaped sealing ring is an annular rubber sealing ring with a circular cross section. It is mainly used for mechanical parts to prevent the leakage of liquid and gaseous media under static conditions. In some cases, the o-shaped sealing ring can also be used for axial reciprocating motion And the dynamic sealing element of low-speed rotating motion. According to different conditions, different materials can be selected to adapt to it.

   O-shaped sealing rings are usually selected as large cross-section o-rings as possible. In the case of the same gap, the volume of the o-shaped sealing rings squeezed into the gap should be less than the maximum allowable value of the squeezed into.

   For different types of fixed sealing or dynamic sealing applications, o-ring seals provide designers with an effective and economical sealing element. O-ring is a two-way sealing element. The initial compression in the radial or axial direction during installation gives the o-ring its own initial sealing ability. The sealing force produced by the system pressure and the initial sealing force are combined into the total sealing force, which increases with the increase of the system pressure. The o-ring shows a prominent role in static sealing occasions. However, in appropriate dynamic occasions, o-rings are often used, but it is limited by the speed and pressure of the seal.

Technical data pressure:

   speed:

   The maximum reciprocating speed can reach 0.5m/s under static conditions

   When there is no retaining ring, the maximum pressure can reach 20mpa and the maximum rotation speed can reach 2.0m/s

   When there is a retaining ring, the maximum pressure can reach 40mpa

   Medium and temperature:

   When there is a special retaining ring, the maximum pressure can reach 200mpa, see "Rubber Seal Material Characteristics Table"

   Dynamic pressure

   Maximum compression:

   When there is no retaining ring, the reciprocating motion can reach up to 5mpa static seal: 20% of the diameter of the o-ring

   When there is a retaining ring, a higher pressure dynamic seal: 30% of the diameter of the o-ring
