These years; domestic bearing professional production planning agile expansion; nearly 2,000 bearing companies; more than 900 companies selling more than 5 million yuan in revenue; the number can be described as the world's top. But China's bearing occupation is still exist, such as low production skills, occupation Concentration is not a high-level problem; the distance from the bearing strong country is still far away.
1. China's bearing occupational production concentration is low.
In the international sales of about 30 billion US dollars in sales; the international eight major multinational companies accounted for 75-80. Germany's two major companies accounted for 90% of the national total; five Japanese accounted for 90% of the national total; Its national total of 56. And China's Wazhou and other seven annual sales of more than 1 billion bearing companies; sales accounted for only 28.3 of the full occupation; the top 30 companies' production concentration is only 43. 6 .
2, China's bearing professional development and innovation can be low.
Because most companies are still at a low level in the construction and operation of the innovation system, research and development of capital investment, talent development, etc.; and the research institutes facing professional service are becoming more corporatized; the state has no skills for occupational commons. The input of research; then weakened the function of development for the profession. Therefore; the whole profession "two weak and two less" outstanding; that is, weak research on the fundamental theory; weak participation in the formulation of international standards; less self-created skills; less patented products. The depiction and production skills are basically imitated; decades of consistent system. Product development can be low; today: although the matching rate of domestic hosts reaches 80; but high-speed rail passenger cars, high-end cars, computers, air conditioners, high level Supporting and repairing bearings for important mainframes such as rolling mills; basically relying on imports.
3, China's bearing professional production skills level is low.
China's bearing industry production technology and process equipment skills development is slow; car processing CNC rate is low; grinding processing automation level is low; there are only more than 200 automatic production lines in the country. Most companies; especially in the state-owned old companies as the main force of production is still Traditional equipment. Leading heat treatment process and equipment that are critical to bearing life and reliability; such as control atmosphere heating, double refinement, bainite quenching and other low coverage; many skill problems have not been broken. Bearing steel Development of new steel grades; advancement of steel quality; development of related skills such as smoothing, cooling, cleaning and abrasives; it is not yet able to adapt to the needs of bearing product level and slow quality improvement. Therefore, the formation process can be low index; poor consistency; product processing The scale dispersion is large; the product connotation quality is unstable and affects the accuracy, function, life and reliability of the bearing.
Aligned with the above situation; China has put forward the "Eleventh Five-Year Plan" for bearing occupation; China's bearing profession will be market-oriented, the company as the main body; promote independent innovation and depicting production skills; promote large group, "Xiaoweiren" company Construction; Progress Center Competitiveness; Progressive Production Concentration; Completed the transition from planning to quality-effectiveness. In 2010, some companies reached some levels of international competitiveness; laid the foundation for the international bearing power team. Completed in 2020 The goal of the team that produces the big countries into the international bearing powers; to contribute to the acceleration of the revitalization of China's equipment manufacturing operations. In 2020, the international bearing strong country policy was completed; the product precision, function, life and reliability reached the same level as foreign large companies in the same period. Product level; severely equipped with supporting bearings to complete localization: depiction and production skills reached the level of large companies outside the circle; there are a number of independent intellectual property rights of central skills, 3-5 have independent intellectual property rights and internationally renowned brands, international competitiveness Strong advantage company, professional production and sales master plan is in the forefront of the world There are 2-3 domestic holding company into the top 10 international forehead bearing the sale, professional production concentration to reach 80 or more.
