Classification of rubber seal rings

The rubber sealing ring is an annular cover composed of one or several parts, which is fixed on a ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap to prevent the leakage of lubricating oil and the intrusion of foreign objects.

1. O-ring series

With fluororubber, nitrile rubber, silica gel, ethylene propylene rubber, bifluororubber and other materials, it is widely used in various machinery, resistant to various petroleum base oils and various chemical media: the use of different types of rubber can meet- Temperature range of 60°C-+200°C (Double fluorine rubber FFKM can reach above 300°C after a specific vulcanization method), operating pressure range: <10MPa (hydraulic), <1MPa (pneumatic) <16MPa (static seal) Nitrile Rubber and gasoline-resistant (90, 93, 97) expansion rate is 0.

2. Y-shaped sealing ring

Products made of various materials such as fluorine rubber, nitrile rubber, and chlorine rubber are widely used in hydraulic, mechanical, pneumatic and other industries. Resistant to various types of petroleum base oils with excellent wear resistance, different types of rubber can be selected to meet the temperature range of -60°C-+200°C.

3. V-shaped sealing ring

It is an axially acting elastic rubber sealing ring, which is used as a pressureless seal for the rotating shaft. The sealing lip has better mobility and adaptability, can compensate for large tolerances and angle deviations, can prevent internal grease or oil from leaking out, and can also prevent external splashing water or dust from intruding.

4. YX type sealing ring for hole

A brief description of the product's use: used for the sealing of 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: HS85±2°A Working temperature: TPU: -40～+80℃CPU: -40～+120℃ Working pressure: ≤32Mpa Working medium: hydraulic oil, emulsion

5. YX type hole retaining ring

Brief description of 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℃ Working medium: hydraulic oil , emulsion, aquatic products Hardness: HS92±5A Material: PTFE
