Detailed explanation of the working principle and application scenarios of oil seals

>Basic concepts of oil seals
Oil seal, as a general term for lubricating oil sealing, is widely used in various mechanical fields. It effectively prevents lubricant leakage by isolating the components that require lubrication from the output components. There are many types of oil seals, but commonly referred to as rotary shaft lip seals, also known as TC oil seals, this type of double lip oil seal is completely covered by rubber and has a self tightening spring, which has a good sealing effect.
>Material selection
In terms of material selection, oil seals usually use high-performance materials such as nitrile rubber, fluororubber, silicone rubber, etc. These materials not only have excellent compatibility with the working medium, but also can adapt to a wide range of working temperatures. In addition, the ability of the lip of the material to follow the high-speed rotation of the rotating axis is also an important factor to consider when selecting.
>Application scenarios
Oil seals have a wide range of application scenarios, including engines, transmissions, rear axles, and other parts. For example, the crankshaft front and rear oil seals, valve oil seals, and transmission front and rear oil seals in the engine all require oil seals to ensure the sealing of lubricating oil. Meanwhile, the half shaft oil seal and differential oil seal of the rear axle are also important application areas for oil seals.
