Belt conveyors are widely used in various industries. The line of the belt conveyor line can be selected according to the requirements of the transportation, and it is also an economical type of material transportation equipment that is indispensable for rhythmic flow operations. The bearing of the conveyor is Fixed parts in machinery. When the other parts are in relative motion with each other on the shaft, the mechanism for holding the center of the shaft and controlling the movement is called a conveyor bearing.

China is one of the first countries in the world to invent rolling bearing bearings. In ancient Chinese books, the structure of axle bearings has been documented for a long time. Judging from archaeological relics and materials, China's oldest bearings with modern rolling bearing structure prototypes appeared in Xuejiaya Village, Yongji County, Shanxi Province, from 221 to 207 BC (Qin Dynasty). Since the founding of New China, especially since the 1970s, under the strong push of reform and opening up, the conveyor bearing industry has entered a new period of high quality and rapid development. At the end of the 17th century, C. Vallo of the United Kingdom designed and manufactured conveyor ball bearings and installed them on a postal train and P. Worth of the United Kingdom obtained patents for ball bearings.
At the end of the eighteenth century, Germany's HR Hertz published a paper on the contact stress of conveyor ball bearings. Based on the achievements of Hertz, R. Stiebeck of Germany and A. Pamgren of Sweden have conducted extensive tests and contributed to the development of design theory and fatigue life calculation of conveyor rolling bearings. Subsequently, Russia's NP Petrov applied Newton's viscous law to calculate conveyor bearing friction. O. Reynolds of the United Kingdom conducted a mathematical analysis of Thor's findings and derived the Reynolds equation, which laid the foundation for the hydrodynamic lubrication theory. In the 50 years since the founding of the People's Republic of China, the bearing industry of belt conveyor equipment in China has achieved remarkable achievements.
