Product introduction of automobile water pump shaft bearing

Automobile water pump shaft bearings are our superior products. The monthly output is 200,000 sets. They are generally used in various water pumps and oil pumps, and have won praise from Chinese and foreign customers.

The water pump is composed of a water pump housing, shaft bearing, water seal, impeller, fan and transmission parts. Automobile water pump shaft bearing is an important part of the water pump. Due to the high speed of the water pump,

Ordinary water pumps have a rotating speed of 6000r/min, and high-speed pumps have a rotating speed of 9000r/min. Therefore, the shaft bearing is required to have a higher load-bearing capacity, so as to meet the requirements of the pump

The life expectancy at a certain speed. The space position of the water pump is restricted, the heat dissipation area is small, and the working conditions are bad. Therefore, the automobile shaft bearing should be able to maintain normal under high temperature.

It is difficult to seal the bearing without reducing the load capacity of the bearing. The reliability and durability of the seal will directly affect the operability of the pump. In short, the shaft connection

Bearing capacity, working clearance and sealing performance are three important performance indicators that affect the performance of water pumps.

Automotive water pump bearings

With the development of automobiles in the direction of high speed, high reliability, and low energy consumption, cooling water pumps are also required to be developed in the direction of light weight, small size, large flow, and high speed. The shaft bearing is a kind of load capacity and good rigidity. A new type of bearing with high rotation accuracy, long service life, reasonable structure and reliable work. At present, it is not only widely used in automobile cooling water pumps, but also widely used in textile machinery and engineering machinery.
