Oil seal is generally another kind of seal, it is usually used to seal the oil mechanical components. It is mainly in the transmission parts need to lubricate the components and components of the isolation, and will not let the oil leakage. Oil seal is usually divided into two types of monomer and assembly. Monolithic type is mainly used in special oil seal, while the assembly type is through the skeleton and lip free combination.
Oil seals are generally made of nitrile rubber, fluororubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene and other materials. Oil Seals So choose to use the oil seal to consider the characteristics of the working medium, so the oil seal is generally used in the engine before and after the crankshaft and camshaft or the transmission before and after the shift lever oil seal.
As the oil seal structure is simple, it is easy to manufacture, it also has a light weight, less supplies, use and testing are very convenient, the price is very cheap, Oil Seals good sealing performance, long service life and so on.
Oil seal it and the characteristics of the mechanical seal is not the same, because the oil seal of the production of materials, so the oil seal the working medium temperature can not exceed 50 degrees, and the use of mechanical equipment installed in the oil seal, Oil Seals be sure to check its sealing and installation is consistent skills requirement.
Features of oil seal
1, oil seal structure is simple, easy to manufacture. Simple oil seal can be molded once, even the most complex oil seal, the manufacturing process is not complicated. Metal skeleton oil seal only through the stamping, gluing, mosaic, molding and other processes can be composed of metal and rubber seals required.
2, oil seal light weight, less supplies. Each oil seal is a combination of thin-walled metal parts and rubber parts, the material consumption is very small, so the weight of each oil seal is very light.
3, the oil seal installation location is small, small axial size, easy processing, Oil Seals and make the machine compact.
4, oil seal the sealing function is good, long service life. The vibration of the machine and the eccentricity of the spindle has a certain degree of adaptability.
5, oil seal demolition easy, easy to test.
6, oil seal cheap.
