What is the difference between industrial bearing steel and automotive bearing steel?

There are some differences between industrial bearing steel and automotive bearing steel in terms of composition, properties and applications.1. Composition: The carbon content of industrial bearing steel is generally between 0.5% and 1.65%, and it also contains chromium, manganese and other alloying elements to improve the hardness and corrosion resistance of the steel. The carbon content of automobile bearing steel is relatively high, generally around 1%, and a certain amount of tungsten, vanadium and other elements are also added to improve the hardness and wear resistance of the steel.

2. Performance: Industrial bearing steel has higher requirements for hardness, strength and wear resistance, and can withstand larger loads and long-term operation. Automotive bearing steel needs to have the characteristics of high hardness, high wear resistance and high fatigue resistance, and can maintain stable performance under high temperature, high speed and complex driving conditions.

3. Application: Industrial bearing steel is mainly used to manufacture bearings, rolling contact parts, etc. for various industrial machinery and equipment, such as mining machinery, textile machinery, reducers, etc. Automotive bearing steel is mainly used to manufacture bearings, wheel hub bearings, gearbox bearings, etc. in automobiles, which need to ensure safe and stable performance under complex driving conditions.

There are certain differences between industrial bearing steel and automotive bearing steel in terms of composition, performance and application. Appropriate materials need to be selected according to specific application scenarios.
