Introduction of metric oil seals online

The principle of metric oil seals online involves two factors: one is the dynamic seal, which is the contact between the sealing lip and the surface of the rotating shaft, and is the most important function of the oil seal; Targeting.
metric oil seals online A layer of hydrodynamic oil film is formed between the lip and the shaft interface. This layer of oil film can serve as a seal. This layer of oil film can not only play the role of sealing the fluid medium, but also play the role of lubrication between the lip and the shaft. However, under dynamic conditions, metric oil seals online often coexist in the states of boundary lubrication, fluid lubrication and dry friction lubrication. Therefore, a good sealing function can be achieved by ensuring that the thickness of the oil film is in a proper range.
The metric oil seals online the advantages of simple structure, light weight, small installation position, and easy processing.

Nitrile rubber
Nitrile rubber of metric oil seals online (made by butadiene and acrylonitrile by emulsion polymerization method) has extremely poor cold resistance and relatively good heat resistance; wear resistance increases with the increase of acrylonitrile content, good water resistance, and good oil resistance , Is the most widely used rubber in the sealing industry.
Silicone Rubber
Silicone rubber of metric oil seals online has excellent weather resistance, extremely poor alkali resistance, weak wear resistance and low tensile strength, so it is generally not used for dynamic sealing; its high temperature resistance is only lower than that of fluoro rubber, but its low temperature resistance is among rubber materials * Ok.
Fluororubber
Fluorine rubber of metric oil seals online has good oil resistance and poor cold resistance. Fluorine rubber is the most stable and balanced one among all rubbers, and it is also the best high-temperature resistant rubber in the rubber industry. The price is relatively expensive; it has good abrasion resistance and can be used in dynamic In a sealed environment.
Acrylic rubber
Acrylic rubber of metric oil seals online has excellent oil resistance at high temperatures, but poor cold resistance and water resistance; abrasion resistance is not as good as polyurethane rubber; stable performance in lubricants containing phosphorus, sulfur, and chlorine additives.
Butyl rubber
Butyl rubber of metric oil seals online has good weather resistance, but it is extremely resistant to water, excellent resistance to ozone and chemical corrosion; poor self-adhesion and mutual adhesion, and poor compatibility. It is not suitable to be used together with the same material. It can only be used with ethylene-propylene rubber and polyethylene. .
Ethylene propylene rubber
The aging resistance of ethylene-propylene rubber is the best. Similarly, its weather resistance and water resistance are very good, and it has extremely high chemical stability, but its oil resistance is also very poor. It has the same self-adhesion and mutuality as butyl rubber. Poor viscosity.
Teflon
Polytetrafluoroethylene of metric oil seals online is resistant to strong acids and bases, has good oxidation resistance, high temperature and low temperature resistance, and excellent weather resistance. Among solid materials, it has the lowest friction coefficient, the smallest surface tension, resulting in high lubricity and strong non-adhesion. However, its radiation resistance is poor, it will degrade after being exposed to high-energy radiation, and it has poorer elasticity than other rubbers.
