As the necessary rotation component in engines, transmissions and wheels, automobile bearings play an important role in reducing friction, and driving engine power to wheels.
The main bearing type used is small deep groove ball bearings, accounting for 27% of all automobile bearings. The functions of the bearings in the engine are self-centering, bearing the pressures and gravity, making the axle parallel, positioning the wheelbase and reducing frictions to ensure engine operations will be safe, reliable and durable at all circumstances, including different speeds, loads and temperatures.
