1. The structure and working principle of rolling bearing ensure that its motion friction coefficient is low, the friction force is small, and it has good mechanical efficiency. In the process of mechanical equipment operation, it can maintain low power consumption and good starting performance.

2, rolling bearings have good accuracy and speed, can meet the operation requirements of a variety of mechanical equipment. Rolling bearings suffer from small friction and low wear in the operation of equipment, so they have a long service life. There are some products in rolling bearings, which can realize the function of automatic aligning, and more widely meet the needs of industrial production.

3, rolling bearing compact structure, small volume, light weight, convenient installation and disassembly. The various parts of rolling bearings have realized the standardization of size, which is not only conducive to the production of rolling bearings, but also conducive to the exchange of rolling bearing parts, making it easier to repair and maintenance.

4. Most rolling bearings use bearing steel as the main material, and the standardized and serialized parts design is more conducive to large-scale industrial manufacturing and stable quality assurance.
