The core component of the machine cooling system integrates the functions of the drive shaft and bearings, featuring high rigidity and compact structure, which directly affects the service life and noise level of the water pump
The automotive water pump shaft integrated bearing is an integrated bearing assembly. Its shaft serves as the inner ring of the bearing, with the raceway directly machined on the shaft. The outer ring is an integral structure, and both sides are sealed with seals. Its main function is to support the rotation of the water pump impeller, enabling the circulation of coolant between the engine water jacket and the radiator, ensuring that the engine operates at an optimal temperature of 80-90℃. Compared with traditional split bearings, it has a smaller radial size, higher rigidity, and is easy to install and disassemble. It has been widely adopted in Europe, America, Japan and other countries.
