The function of O-ring is to seal and ensure the sealing performance of containers such as cylinders.

O-ring is a type of rubber sealing ring with a circular cross-section. Due to its O-shaped cross-section, it is called an O-ring or O-ring. It began to appear in the mid-19th century, when it was used as an O-ring component for steam engine cylinders.

1. O-ring specifications and models mainly include UHSO ring specifications, UHPO ring specifications, UNO ring specifications, DHO ring specifications, piston rod O-ring specifications, high-temperature resistant O-ring, high-pressure resistant O-ring, corrosion-resistant O-ring, and wear-resistant O-ring.

2. Introduction to O-ring application: YX O-ring for holes Product use: Used for sealing pistons in reciprocating hydraulic cylinders.

3. Scope of application: TPU: general hydraulic cylinders, general equipment hydraulic cylinders.

4. CPU: Hydraulic cylinders for construction machinery and oil cylinders for high temperature and high pressure.

5. Material: Polyurethane TPU, CPU, rubber. Product hardness: HS85 ± 2 ° A Working temperature: TPU: -40~+80 ℃, CPU: -40~+120 ℃ Working pressure: ≤ 32Mpa Working medium: hydraulic oil, emulsion.

6. Application of YX type hole O-ring product: This standard is suitable for use with YX type sealing ring when the working pressure of the oil cylinder is greater than 16MPa, or when the oil cylinder is subjected to eccentric force, to protect the sealing ring Working temperature: -40 to+100 degrees. Working medium: hydraulic oil, emulsion, aquatic product Hardness: HS 92 ± 5A Material: polytetrafluoroethylene.

7. YX O-ring for shafts. Product application: Used for sealing piston rods in reciprocating hydraulic cylinders. Scope of application: TPU: general hydraulic cylinders, general equipment hydraulic cylinders.

8. CPU: Hydraulic cylinders for construction machinery and oil cylinders for high temperature and high pressure. Material: Polyurethane TPU, CPU, Rubber Product Hardness: HS85 ± 2 ° A Working Temperature: TPU: -40~+80 ℃ CPU: -40~+120 ℃ Working Pressure: ≤ 32Mpa Working Medium: Hydraulic oil, emulsion.

9. O-ring has excellent sealing performance and high working life. The working life of dynamic pressure sealing is 5-10 times higher than that of conventional rubber sealing products, and can reach tens of times higher. Under certain conditions, it can have the same life as the sealing substrate.

10. The friction resistance of O-ring is small, and the dynamic and static friction forces are equal, which is 1/2-1/4 of the friction force of "0" - shaped rubber ring. It can eliminate the "crawling" phenomenon of movement at low speed and low pressure.

11. The O-ring is highly wear-resistant and has an automatic elastic compensation function after the sealing surface wears out.

12. O-ring has good self-lubricating performance and can be used for oil-free sealing. The O-ring structure is simple and easy to install. O-ring working pressure: 0-300MPa; Working speed: ≤ 15m/s; Working temperature: -55-250 degrees. O-rings are suitable for media such as hydraulic oil, gas, water, mud, crude oil, emulsion, water ethylene glycol, and acid.
