Since 2006, Focus on rubber seals

Overview of Rubber O-Rings

by:ORK      2022-10-22
O-ring specifications 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 O-rings, high-pressure O-rings Rings, Corrosion Resistant , Wear Resistant . O-ring application introduction: YX-type O-ring for holes Product use: used for the sealing of pistons in reciprocating hydraulic cylinders. Scope of application: TPU: general hydraulic cylinder, general equipment hydraulic cylinder. CPU: hydraulic cylinders for construction machinery and oil cylinders for high temperature and high pressure. Material: Polyurethane TPU, CPU, rubber. Product hardness: HS70±52A Working temperature: TPU: -40~+80℃, CPU: -40~+120℃ Working pressure:≤32Mpa working medium: hydraulic oil, emulsion. O-ring for YX-type hole product use: 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 eccentrically stressed, it plays the role of protecting the sealing ring. Working temperature: -40 ~ +100 Spend. Working medium: hydraulic oil, emulsion, aquatic products Hardness: HS92±5A Material: PTFE. YX-type O ring manufactures for shafts Product use: used for sealing of piston rods 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, Product Hardness: HS85±2°A Working temperature: TPU: -40~+80℃CPU: -40~+120℃Working pressure:≤32Mpa, working medium: hydraulic oil, emulsion. The rubber O-ring has excellent sealing performance and long working life, and the working life of dynamic pressure seal is 5 higher than that of conventional rubber sealing products.—10 times, up to tens of times, and can have the same life as the sealing base under certain conditions. The rubber O-ring has low frictional resistance, and the dynamic and static frictional forces are equal.“0”1/2 of the friction force of the rubber ring—1/4, can eliminate low speed, low pressure movement“crawl”Phenomenon. The rubber O-ring is highly wear-resistant, and has an automatic elastic compensation function after the sealing surface is worn. Good self-lubricating properties of rubber O-rings. Can be used as oil-free lubrication seal. The rubber O-ring has a simple structure and is easy to install. O-ring working pressure: 0-300MPa; working speed:≤15m/s; working temperature: -55-250 degrees. Suitable media for rubber O-rings: hydraulic oil, gas, water, mud, crude oil, emulsion, water-glycol, acid. Edit this paragraph 2. Scope of application of rubber O-rings O-rings are suitable for being installed on various mechanical equipment, under specified temperature, pressure, and in different liquid and gaseous media, in static or moving states. effect. 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. O-rings are mainly used for static sealing and reciprocating sealing. When used for rotary motion seals, it is limited to low-speed rotary seals. The rubber O-ring is generally installed in the groove with a rectangular cross-section on the outer or inner circle to play a sealing role. O-rings still play a good role in sealing and shock absorption in environments such as oil resistance, acid and alkali resistance, grinding, and chemical erosion. Therefore, rubber O-rings are the most widely used seals in hydraulic and pneumatic transmission systems. Edit this paragraph 3. Advantages of rubber O-rings Compared with other types of sealing rings, rubber O-rings have the following advantages:--Suitable for a variety of sealing forms: static sealing, dynamic sealing, suitable for various materials, sizes and grooves The grooves are standardized and highly interchangeable - 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 can effectively seal oil, water, air, gas and various chemical media through the selection of appropriate rubber materials and appropriate formula design. The temperature range is wide (-60℃~+220℃), and the pressure can reach 1500Kg/cm2 in fixed use (used together with the reinforcing ring). --Simple design, compact structure, easy assembly and disassembly. Since the rubber O-ring itself and the structure of the installation part are extremely simple and standardized, it is very easy to install and replace. --The variety of materials can be selected according to different fluids: nitrile rubber (NBR), fluorine rubber (FKM), silicone rubber (SIL), EPDM rubber (EPDM), neoprene rubber (CR), natural rubber (NR) Hydrogenated Nitrile Butadiene (HNBR), Butyl (IIR), Silicone Fluorine (FLS), etc.--Low Cost Company Website:
