O-ring is suitable for installation in all kinds of mechanical equipment, in the specified temperature, pressure, as well as different liquid and gas medium, at rest or motion of the sealing effect. In machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and all kinds of instruments and meters, a large number of applications of various types of sealing components. O-ring is mainly used for static sealing and reciprocating sealing. Used for rotating motion sealing, low speed rotary sealing device. O-type sealing ring is generally installed in the outer circle or rectangular groove on the inner circle for sealing. O-ring in oil resistance, acid and alkali, grinding, chemical erosion and other environments still play a good sealing, damping role. Therefore, o-ring is a widely used seal in hydraulic and pneumatic transmission system.
Compared with other types of sealing ring, O-ring has the following advantages:
Suitable for a variety of sealing forms: static seal, dynamic seal
Suitable for all kinds of materials, dimensions and grooves have been standardized, strong interchangeability
-- Suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion)
Suitable for many different sealing media: oil, water, gas, chemical media or other mixed media
Through the selection of appropriate rubber materials and appropriate formula design, to achieve effective sealing effect on oil, water, air, gas and various chemical media. Wide range of temperature (-60℃~+220℃), fixed use of pressure up to 1500Kg/cm2 (with the reinforcement ring).
-- Simple design, compact structure, convenient assembly and disassembly
O-ring section structure is simple, and has self-sealing function, sealing performance is reliable.
Because the o-ring itself and the installation part of the structure are simple, and has formed a standard, so it is easy to install and replace.
Material varieties: Nitrile rubber (NBR), fluorine rubber (FKM), silicone rubber (VMQ), ethylene propylene rubber (EPDM), chloroprene rubber (CR), butyl rubber (BU), polytetrafluoroethylene (PTFE), natural rubber (NR), etc
-- Low cost
-- Relatively small dynamic friction resistance
