5 Common Classifications Of Rubber Sealing Ring

A rubber Sealing Ring is an annular cover composed of one or several parts, which is fixed on one ferrule or washer of the bearing and contacts with another ferrule or washer or forms a narrow labyrinth gap to prevent the leakage of lubricating oil and the intrusion of foreign objects. 5 Categories of Rubber Sealing Ring

1. O-ring series
With fluorine rubber, nitrile rubber, silicone, ethylene propylene rubber, double fluorine rubber, and other materials, it is widely used in various machinery, and resistant to various petroleum-based oils and various chemical media: the use of non-rubber species can meet- In the temperature range of 60℃-+200℃ (dual fluororubber FFKM can reach more than 300 degrees after a specific vulcanization method), the operating pressure range: <10MPa (hydraulic), <1MPa (pneumatic) <16MPa (static seal) Nitrile The expansion ratio of rubber and gasoline resistant compounds (90, 93, 97) is 0.

2. Y-shaped sealing ring
Products made of fluorine rubber, nitrile rubber, chloro rubber, and other materials are widely used in hydraulic, mechanical, pneumatic, and other industries. All kinds of resistant petroleum-based oils have excellent wear resistance, and different rubber types can be selected to meet the temperature range of -60℃-+200℃.

3. V-shaped sealing ring
It is an axially acting elastic rubber sealing ring used as a pressureless seal for the rotating shaft. The sealing lip has good mobility and adaptability, can compensate for large tolerances and angular deviations can prevent the internal grease or oil from leaking out, and can also prevent the intrusion of external splashing water or dust.

4. YX type sealing ring for hole
Brief description of 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: HS85±2°A Working temperature: TPU: -40～+80°C CPU: -40～+120°C Working pressure: ≤32Mpa Working medium: hydraulic oil, emulsion.

5. YX type hole with retaining ring
Briefly describe the use of the product: This standard is suitable for use with the 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 ℃ Working medium: hydraulic oil, Emulsion, aquatic products Hardness: HS92±5A Material: PTFE.
