Introductions of The Oil Seal For Mercedes-Benz 170*190*8.5/9.5 OE 0059978447
Skeleton oil seal is an important mechanical sealing element. It has the following characteristics:
1. Solid Structure:
The metal skeleton gives the oil seal high strength and stability and can withstand a certain amount of pressure. The rubber sealing part is soft and can closely adhere to the rotating shaft, effectively preventing fluid leakage.
2. Sealing Principle
The sealing lip always maintains appropriate contact pressure with the rotating shaft under the action of the spring. When the shaft rotates, an extremely thin oil film is formed between the sealing lip and the shaft, which not only plays a lubricating role, but also achieves a sealing function. The oil seals have a single-lip oil seal and a double-lip oil seal. The second lip of the double-lip oil seal prevents dust, so that dust and impurities will not enter the inside of the machine.
3. Widely Used
In the automotive field, it can be used in engines, transmissions and other parts to prevent leaks of oil, lubricants, etc. In industrial equipment, such as pumps, fans, compressors, etc., it also plays a key sealing role.
4. Selection And Installation Points
According to different working environments and sealing requirements, select a framework oil seal with appropriate material, size and performance. During installation, ensure that the installation parts are clean to avoid damage to the oil seal, and the installation direction and position should be correct to ensure its sealing effect.
The oil seal is an oil-sealing sealing element used to seal the rotating shaft in mechanical equipment, while the cavity is basically static (see the figure below)
Therefore, the oil seal is also called the rotating shaft lip seal ring.

Different Types of The Oil Seal
Advantages of FKM oil seals
The advantages of FKM (Fluororubber) oil seals mainly include their excellent high temperature resistance, corrosion resistance, compression permanent set performance, low temperature resistance, weather aging resistance and ozone resistance.
1. High Temperature Resistance: Fluororubber (FKM) can work for a long time at 200-250 degrees Celsius, can work for a short time even at 300 degrees Celsius, shows its excellent high temperature resistance.
2. Corrosion Resistance: Fluororubber has excellent stability to organic liquids, different fuel oils and lubricating oils, and has good corrosion resistance to most organic acids, hydrocarbons, benzene and toluene.
3. Compression Set Performance: In the sealing application of fluororubber at high temperatures, its compression set performance is the key. Viton type fluororubbers are widely used because of their improvement in compression deformation.
4. Low Temperature Resistance: The limit temperature at which fluororubber can maintain elasticity is-15 to 20 degrees. As the temperature decreases, its tensile strength becomes larger, and it appears strong at low temperatures.
5. Weathering Resistance And Ozone Resistance: The performance of fluororubber is still satisfactory after 10 years of natural storage. In air with an ozone concentration of 0.01%, There is no obvious cracking after 45 days of action.
In addition, due to its good self-lubricating properties and better effect after adding bronze, fluoroelastomer is suitable for use in the aviation, automotive and chemical processing industries
