Precision bearings have become a key development industry in the national “Twelfth Five-Year Plan

The bearing is a component that fixes and reduces the friction coefficient of the load during the mechanical transmission process. When other parts move relative to each other on the shaft, it is used to reduce the friction coefficient during power transmission and keep the shaft center position fixed. Bearings are an important part of contemporary machinery and equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission of the equipment.
my country is one of the earliest countries in the world to invent rolling bearings. There are long records about the structure of axle bearings in Chinese ancient books. Bearings are important basic components of various mechanical equipment. Its accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the host. Among mechanical products, bearings are high-precision products, which not only require comprehensive support from many disciplines such as mathematics and physics, but also require material science, heat treatment technology, precision machining and measurement technology, numerical control technology, effective numerical methods and powerful computers Technology and many other disciplines serve it, so the bearing is a product that represents the country’s scientific and technological strength.

The development momentum of my country’s bearing manufacturing industry is strong, which will bring positive effects to the steady improvement of the bearing steel market. The demand for a number of high-end bearings has increased significantly, such as aerospace bearings, high-speed precision bearings for machine tool spindles, precision angular contact ball bearings for ball screw support, high-speed electric spindle bearings, precision bearings for machine tools in the photovoltaic industry, turntable bearings, wind turbine bearings, Joint bearings for shield machines, rolling mill bearings, high-speed rail bearings, automotive bearings, pulley bearings for cranes, turbocharger bearings, hydrodynamic bearings, etc.

After more than 50 years of construction and development, my country’s bearing industry has realized a development strategy ranging from small to large, and weak to strong, forming a relatively complete industrial system with basically reasonable production layout, coexistence of large and medium-sized enterprises, and relatively complete product categories. And has a larger production capacity and strong technical strength
