Rubber O-ring is a device used for piston sealing in reciprocating hydraulic cylinders, made of polyurethane TPU, CPU, rubber. Excellent sealing performance and long working life. The working life of dynamic pressure sealing 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 matrix. Mainly used in occasions where sealing is required.
Rubber O-ring classification
There are mainly UHSO-rings, UHPO-rings, UNO-rings, DHO-rings, piston rod O-rings, high-temperature-resistant O-rings, high-pressure-resistant O-rings, corrosion-resistant O-rings, and wear-resistant O-rings.
YX-type O-rings for holes 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.
Application of YX-type O-ring for holes: This standard is applicable to use with a YX-type sealing rings when the working pressure of the oil cylinder is greater than 16MPa, or to protect the sealing ring when the oil cylinder is eccentrically stressed.
YX type O-ring for shaft product application: used for sealing the piston rod in the reciprocating hydraulic cylinder
scope of application
Rubber O-ring seals are suitable for installation on various mechanical equipment, and play a sealing role in static or moving states under specified temperatures, pressure, and different liquid and gas media. Various types of sealing elements are widely used in sanitary ware, ships, automobiles, hardware, electronics, toys, electrical appliances, aerospace equipment, machinery, and various instruments and meters. Rubber O-rings are mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing devices. The rubber O-ring is generally installed in a groove with a rectangular cross-section on the outer circle or the inner circle to act as a seal. Rubber O-ring seals still play a good role in sealing and shock absorption in environments such as oil resistance, acid and alkali, abrasion, and chemical erosion. Therefore, the rubber O-ring is the most widely used seal in hydraulic and pneumatic transmission systems.
