The shaft on which the oil seal is mounted has to be ground to a rough surface finish. The shaft also should be hardened to prevent grooves forming on the shaft when the pressure is exerted by the spring on the seal. The area where the seal is fitted also has to be ground to prevent grooves that tend to wear out the lip of the oil seal faster than normal.

(3) The oil seal with general pressure has poor pressure bearing capacity, and the oil seal will deform when the pressure is too large. In the case of excessive pressure, a pressure-resistant bearing ring or a reinforced pressure-resistant oil seal should be used.
One of the key factors that determine the effectiveness of an oil seal is its material composition. High-quality materials such as nitrile rubber, fluoroelastomers, and silicone are commonly used due to their resistance to heat, oil, and chemicals. These materials provide excellent flexibility and durability, ensuring that the seal can withstand the rigors of constant use These materials provide excellent flexibility and durability, ensuring that the seal can withstand the rigors of constant useIn modern vehicles, spark plug wires have been replaced by direct ignition systems, which eliminate the need for a distributor
The metal case is the exterior (or frame) of the oil seal, the principal function of which is to give rigidity and strength to the seal. The material of the case must be selected depending on the environment where the seals are to be used. Often the metal case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the oil seal in the housing bore. Common case material types are:
Installation inaccuracies
Oil leaks are more than just a mess; they signal a loss of the lubricant crucial for your engine's health. As the oil level drops, engine components run the risk of overheating or even seizing up, leading to costly repairs or, in severe cases, engine failure. Moreover, the introduction of dirt and debris through a compromised gasket can cause wear on the camshaft and valve train, reducing the engine’s efficiency and longevity.
