The O-ring rubber seal uses low-friction polytetrafluoroethylene (PTFE) and is composed of a ring and an O-ring rubber seal. The O-ring provides sufficient sealing preload and compensates for the wear of the PTFE ring. The friction resistance of PTFE seals is small, and the sound friction resistance is close to that of seals.
Suitable for cylinder piston rod sealing in high and low speed repetitive motion and high pressure systems. Two stepped sealing rings can achieve zero leakage effect.
1. Characteristics of O-type rubber sealing ring:
1. Easy to install, because the O-type rubber sealing ring itself and the installation position are extremely simple in structure and have been standardized, so installation and replacement are easy.
2. Compact structure and good sealing performance. The cross-section structure of the O-type rubber sealing ring is extremely simple, has a self-sealing function and reliable sealing performance.
3. Wide range of application. With appropriate plastic materials and proper formula design, oil, water, air, gas and various chemical media can be effectively sealed. It has a wide temperature application range (-60℃~220℃), and the pressure can reach 1500kg/cm2 when used in a fixed manner (used together with the reinforcement ring).
4. There are a wide variety of materials suitable for various purposes, and the sizes and trenches have been standardized.
2. Application scope of O-type rubber sealing ring:
O-type rubber sealing rings are widely used in seals for diesel locomotives, vehicles, tractors, engineering machinery, machine tools, and various hydraulic and pneumatic components. They can withstand fixed, reciprocating, and rotating seals. O-type rubber sealing rings account for 10% of mechanical product seals. of more than 50%.
According to customer needs, Delong Sealing Technology Co., Ltd. can produce heat-resistant, low-temperature vacuum, high-pressure, various special-purpose sealing rings and special-shaped rubber sealing products for different media.
