Product Description
Automobile crankshaft oil seal is an important sealing element in the engine. Its main function is to prevent the leakage of lubricating oil and coolant inside the engine, and at the same time prevent external impurities and pollutants from entering the engine to maintain the normal operation and performance of the engine. Crankshaft oil seal is usually installed at the front or rear end of crankshaft to seal the gap between crankshaft and crankcase and prevent leakage of lubricating oil and coolant.
The materials of automobile crankshaft oil seal usually include the following:
1. Rubber: Rubber is a common crankshaft oil seal material with good elasticity and sealing performance, which can effectively prevent the leakage of lubricating oil and coolant. Rubber crankshaft oil seal is usually made of oil-resistant and high-temperature resistant rubber materials such as nitrile rubber (NBR) or fluororubber (FKM).
2. Metal: The metal part of the crankshaft oil seal is usually made of metal materials such as stainless steel or aluminum alloy, which is used to support and fix the rubber sealing ring to ensure the stability and tightness of the crankshaft oil seal in high-speed rotation and high-temperature environment.
3. Reinforcing materials: Some crankshaft oil seals will also add reinforcing materials, such as graphite, asbestos or glass fiber, to enhance their wear resistance and durability. These reinforcing materials can improve the service life and stability of crankshaft oil seal.
Generally speaking, the main function of oil seal of automobile crankshaft is to prevent the leakage of lubricating oil and coolant, prevent external pollutants from entering the engine and protect the normal operation of the engine. The materials of crankshaft oil seal usually include rubber, metal and reinforcing materials, which together ensure that crankshaft oil seal has good sealing performance, durability and stability, and ensure the reliability and performance of engine.
