For Mercedes-Benz 145-175-13/15 series trucks, the core component requirements are not only reflected in engine performance and chassis stability, but also in the seemingly inconspicuous but vital small parts-oil seals. As one of the key parts of the mechanical movement, high-quality oil seals can significantly reduce the risk of lubricating oil leakage, protect internal components from external pollution, and extend the life of the vehicle.

Choose a good oil seal is inseparable from the cognition of its material. At present, the mainstream materials on the market mainly include natural rubber, nitrile rubber (NBR), fluorine rubber (FKM) and polyurethane and other high-performance compounds. Among them, natural rubber is known for its excellent elasticity and heat resistance, which is especially suitable for applications in low-speed operating environments; while fluorine rubber is more suitable for use under high-load conditions due to its strong chemical corrosion resistance and high temperature adaptability. The oil seals we offer are precision machined to provide excellent reliability in a variety of complex road conditions.

The correct installation method is also one of the prerequisites for ensuring the long-term stable operation of the oil seal. First of all, it is necessary to carefully check whether the parts to be installed are clean and flat. Any residual impurities will adversely affect the subsequent assembly. Secondly, it is recommended to use professional tools to gradually press in rather than forcibly knock, which can effectively prevent the occurrence of lip deformation or damage. The last step is to test the sealing effect and put it into actual operation after confirming it is correct.

However, there are still many easily overlooked problems in daily practice that may lead to premature failure of oil seals. For example, it is common to fail to standardize the operation process according to the manufacturer's instructions, change the specifications and models at will, or even choose inferior substitutes. These problems may appear temporarily without obvious symptoms, but over time will inevitably accelerate the aging process and shorten the service life. Therefore, please be sure to follow the specific advice given by professionals to avoid potential risks.

in order to better prove the advantages of our products, we now share a real application case for reference: a batch of Mercedes-Benz heavy transport vehicles under a logistics company frequently have rear axle oil leakage failures, which seriously affects normal operating efficiency. After switching to customized high-end oil seals produced by our company, all vehicles have returned to smooth operation and similar conditions have not occurred again so far.

In addition to the initial selection and installation, regular maintenance in the later period should not be taken lightly. Simple steps such as applying an appropriate amount of grease on the contact surface to form a protective film layer during each maintenance, avoiding long-term exposure to direct sunlight to prevent hardening and cracking, etc. can greatly delay the wear speed and improve the overall economic benefits. It is more wise and reasonable to purchase at a low price.
