In recent years, the domestic bearing industry has rapidly expanded its production scale, with nearly 2,000 bearing companies, of which more than 900 have sales revenues of more than 5 million yuan, and the number is the largest in the world. However, the bearing industry in China still exists problems such as low level of manufacturing technology and low industry concentration, and it is still far from the bearing power. 1, China's bearing industry production concentration is low. In the world bearing about 30 billion US dollars in sales, the world's eight major multinational companies accounted for 75-80. Germany's two major companies accounted for 90 of its national total, Japan 5 accounted for 90 of its national total, and the United States accounted for 56 of its national total. In China, bearing companies with seven annual sales of more than one billion yuan, such as tile shafts, accounted for only 28.3 percent of the industry's total sales. 2. China's bearing industry has low R&D and innovation capabilities. Since most enterprises are still at a low level in the construction and operation of innovation systems, capital investment in R&D and innovation, and talent development, and with the development of scientific research institutes for industrial services, the country has no research on common technologies in the industry. The investment has weakened the R&D capabilities for the industry. Therefore, the whole industry is characterized by “two weak and two weakâ€, that is, basic theoretical research is weak, participation in international standard formulation is weak, less original technology, and less patented products. At present, our design and manufacturing technologies are basically analog and have been consistently implemented for decades.
