In recent years, the production scale of the domestic bearing industry has expanded rapidly, ranking fourth in the world. There are nearly 2,000 bearing companies, of which more than 900 companies have sales revenue of more than 5 million yuan, ranking first in the world. However, my country's bearing industry still has problems such as low level of manufacturing technology and low industry concentration, which is still far from the standard of a powerful bearing country.

1. The manufacturing technology level of my country's bearing industry is low.

The development of manufacturing technology and process equipment technology in my country's bearing industry is slow, the numerical control rate of turning is low, and the level of automation in grinding is low. There are only more than 200 automatic production lines in the country. Most enterprises, especially the old state-owned enterprises, still use traditional equipment as the main production force. Advanced heat treatment processes and equipment that are critical to bearing life and reliability, such as controlled atmosphere protection heating, double refinement, bainite quenching, etc., have low coverage, and many technical problems have failed to make breakthroughs. The research and development of new steel grades of bearing steel, the improvement of steel quality, and the research and development of related technologies such as lubrication, cooling, cleaning and abrasive tools cannot meet the requirements of improving the level and quality of custom bearings products. As a result, the process capability index is low, the consistency is poor, the dispersion of product processing dimensions is large, and the inherent quality of the product is unstable, which affects the accuracy, performance, life and reliability of the bearing.

2. The production concentration of my country's bearing industry is low.

In the world's bearing sales of about 30 billion US dollars, the world's eight major multinational companies account for 75-80%. The two largest companies in Germany account for 90% of the national total, 5 companies in Japan account for 90% of the national total, and 1 company in the United States accounts for 56% of the national total. And my country's seven custom bearings manufacturer with annual sales of more than 1 billion yuan, the sales only account for 28.3 of the entire industry, and the production concentration of the top 30 enterprises is only 43.6.

3. The R&D and innovation capabilities of my country's bearing industry are low.

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 the scientific research institutes that serve the industry are becoming enterprises, the country has no research on common technologies in the industry. investment, thereby weakening the function of R&D for the industry. Therefore, "two weak and two small" are prominent in the whole industry, that is, weak basic theoretical research, weak participation in the formulation of international standards, less original technology, and less patented products. Our current design and manufacturing technology is basically analog, consistent for decades. The product development capability is low, as shown in: although the matching rate for domestic main engines reaches 80%, the supporting and maintenance bearings of high-speed railway passenger cars, medium and high-end cars, computers, air conditioners, high-level rolling mills and other important main engines are basically imported.

In 2020, the goal of becoming a world-leading bearing country will be achieved. Product accuracy, performance, life and reliability will reach the level of similar products of large foreign companies in the same period. Bearings for major equipment will be localized: design and manufacturing technology will reach the level of large companies outside the same period. There are a number of core technologies independent intellectual property rights; there are 3-5 advantageous enterprises with independent intellectual property rights and world-renowned brands and strong international competitiveness; the total scale of industrial production and sales ranks in the forefront of the world, and 2-3 domestic holding companies have entered the world bearing Top 10 in sales; industry production concentration reaches more than 80.

In response to the above situation, my country has put forward the "Eleventh Five-Year" plan for the bearing industry. my country's bearing industry will take the market as the guide and enterprises as the main body, promote the upgrading of independent innovation capabilities and design and manufacturing technology, and promote the construction of large groups and "little giants" enterprises. Improve core competitiveness, increase production concentration, and realize the transformation from scale growth to quality and efficiency. In 2010, some products of some enterprises reached the level of international competitiveness, laying the foundation for becoming a world bearing power; in 2020, the goal of becoming a world bearing power from a major linear bearing manufacturers will be realized, and the goal of accelerating the revitalization of my country's equipment manufacturing industry will be made. contribute.
