中文简体The rubber O-ring is a rubber sealing ring with a circular cross-section. Because of its O-shaped cross-section, it is called an O-ring, also called an O-ring. It began to appear in the middle of the 19th century when it was used as an o-ring for the steam engine cylinder as a component.
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-rings, high-pressure resistant O-rings, Corrosion-resistant O-rings, wear-resistant O-rings.
O-ring application introduction: YX-type O-ring for holes Product use: Used for sealing pistons in reciprocating hydraulic cylinders.
Scope of application: TPU: general hydraulic cylinders, general equipment hydraulic cylinders.
CPU: Hydraulic cylinders for construction machinery and oil cylinders for high temperature and high pressure.
Material: Polyurethane TPU, CPU, Rubber.
Product hardness: ±2°A
Working temperature: TPU: -40～+80℃, CPU: -40～+℃
Working pressure: ≤
Working medium: hydraulic oil, emulsion.
Application of YX-type O-ring for holes: This standard is suitable for use with YX-type sealing rings when the working pressure of the oil cylinder is greater than that, or to protect the sealing ring when the oil cylinder is under eccentric force.
Working temperature: -40 ~ + degrees.
Working medium: hydraulic oil, emulsion, water
Product hardness: ±5A
Material: PTFE

The O-ring has excellent sealing performance and a long working life. The working life of the dynamic pressure seal is 5-10 times higher than that of conventional rubber sealing products, up to dozens of times. Under certain conditions, it can have the same life as the sealing substrate. The friction resistance of the O-ring is small, and the dynamic and static friction are equal, which is 1/2-1/4 of the friction of the "0"-shaped rubber ring, which can eliminate the "crawling" phenomenon of low-speed and low-pressure movement. The O-ring is highly wear-resistant and has an automatic elastic compensation function after the sealing surface is worn.
