- The function of the rear shock absorber is to dampen the oscillations caused by uneven road surfaces, thereby reducing the bouncing motion of the car's body. At its heart, the oil seal acts as a barrier, separating the pressurized oil from the external environment. This seal, if damaged, can lead to oil seepage, which not only impairs the shock absorber's performance but also poses potential damage to other vehicle components due to lubrication loss.
Oil seals are protective elements. They prevent the mixing of water and lubricants within a machine, thereby ensuring optimal machine functionality. Also, oil seals help to prevent lubricant leakage at high pressure like when the machine is working at an extremely high rate. Not only that, radial shaft seals stop foreign components from entering a machine. This is because they can contaminate the lubricant and even damage the machine.

Material selection is important to the life of a radial shaft seal. The elastomer’s resistance to temperature, abrasion, chemicals, weather, sunlight, and ozone can affect a profile’s longevity and performance. The two most prevalent materials are Nitrile and Viton. See our Oil Seal Materials page for details on compounds and chemical compatibility.
Rubber gaskets are essential components in many industrial applications, providing a reliable seal between two mating surfaces to prevent leaks or contamination. One common type of rubber gasket is the 40mm rubber gasket, which is used in a variety of industries for different applications.
