Due to the wide range of applications, the variety and complexity of bearing types are determined. Due to strict requirements, the importance of bearing quality and performance is determined. The bearing manufacturing industry is a precision basic component manufacturing industry. Its accuracy is measured in 0.001 millimeters (mm), and the manufacturing tolerance of general mechanical parts is generally only 0.01 mm. The noise and vibration of the motor largely depends on the quality of the bearing; the swing and temperature rise of the spindle of the high-precision machine tool are closely related to the quality of the bearing.
The performance of the bearings in the de-rotation device of a communication satellite directly affects the communication effect; failure of key bearings in aerospace and aviation will cause serious accidents. In short, the mainframes in various fields such as industry, agriculture, national defense, science and technology and household appliances, their accuracy, performance, longevity, YRT turntable bearing reliability and various economic indicators, are closely related to the bearings, and bearing industry Development is also related to the manufacturing level of China's major technical equipment and the export capacity of machinery and equipment. Bearings are playing an increasingly important role in the national economy and national defense construction.
