Bearing is a component that can be fixed and reduced in the process of mechanical transmission. It can also be said that when other parts generate relative motion on each other on the shaft, they are used to reduce the friction coefficient during the power transfer process and to keep the center position of the shaft fixed. Bearing is one of the most important parts in modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the mechanical load friction coefficient of the equipment during the transmission process. According to the friction properties of the moving elements, the bearings can be divided into rolling bearings and sliding bearings.
Bearing is an important basic component of various kinds of mechanical equipment, and its precision, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the host. In mechanical products, bearings are high-precision products and not only require the comprehensive support of mathematics, physics and other disciplines. And it needs to be served by many disciplines such as materials science, heat treatment technology, precision processing and measurement technology, numerical control technology and effective numerical methods and powerful computer technology. Therefore, bearings are also a product that represents the country's scientific and technological strength.
