Application

Bearings are widely used in automobiles and assume important responsibilities. From the engine, the chassis to the electrical assembly, it is applied to the bearing. 

The bearings used in automobiles are divided into two categories: sliding bearings and rolling bearings. 

Sliding bearings are mainly used on engines. Rolling bearings are widely used in various mechanical and electrical assemblies in automobiles. There are mainly transmission, steering gear, water pump, fan, clutch, differential, front and rear wheels and drive shaft.

With the continuous development of the engine to high speed and supercharging, the oil film pressure of the bearing increases, the thickness of the oil film decreases, the working environment of the bearing deteriorates, and the material and manufacturing requirements of the crankshaft and connecting rod bearings are also getting higher and higher.
