recently, China Bearing Industry Association disclosed that the sales revenue and profit growth of China's bearing industry in 2010 exceeded 30%. However, the relevant person in charge of China Bearing Industry Association said that the pressure on the bearing industry will further increase in 2011, and the growth rate of the bearing industry will slow down, which is worthy of attention by bearing enterprises. A person in charge of a bearing enterprise told that the high-end equipment manufacturing represented by energy equipment is now at the peak of development. If the downstream industries such as energy equipment can make technological breakthroughs in high-end bearings, the development level of the bearing industry will be greatly improved

China's independently developed nuclear power supporting bearings march towards high-end bearings during the "12th Five Year Plan"

according to the data of China Bearing Industry Association, the main business income of the bearing industry in 2010 will exceed 100 billion yuan, reaching 120 billion yuan, with a growth rate of 30%. Among them, the demand for small bearings has increased significantly. It is estimated that the annual bearing output will reach 15billion sets, with a year-on-year increase of 36.36%

nuclear power supporting bearings independently developed by China

it is understood that in 2010, the leading enterprises in the national bearing industry developed 528 kinds of supporting bearings for 106 major technical equipment in 13 key fields, with an annual sales revenue of 9.2 billion yuan, and the products reached the level of similar foreign products. It includes how to solve the imbalance of Kenyan gear of the hydraulic universal testing machine that has reached the international advanced level, such as yaw and pitch changing bearings of wind turbine generator sets, secondary pump bearings of nuclear power plants, high-power locomotive bearings, ultra precision Sendzimir mill bearings, sector bearings of continuous casting production lines, etc., and has gradually realized industrialization

relevant persons from China Bearing Industry Association said that during the "12th Five Year Plan" period, the development focus is to significantly improve product quality and technical level, improve the market share of supporting bearings of key main engines, and march into high-end bearing markets such as high-speed railway passenger car bearings, high-power wind turbine bearings, precision CNC machine tool spindle bearings, and large aircraft bearings

support the localization of energy equipment

the technicians of Wazhou group told that bearings are important and key basic parts in the equipment manufacturing industry, which directly determine the performance, level, quality and reliability of major equipment and host products. However, China's high-end bearings, such as high-speed and high-precision machine tool bearings and energy supporting bearings, currently mainly rely on imports

a person in the industry gave an example. Although China has owned the high-speed EMU technology with independent intellectual property rights, the localization application of supporting bearings is still blank. At present, most high-speed bearings in China can only meet the requirements of KM EMUs, while high-speed rail bearings in European and American countries can meet the requirements of km/h. Therefore, at present, the high-speed rail bearings for domestic multiple units with a speed of more than 200 kilometers per hour basically rely on imports

in the field of energy equipment, bearings are also a key component that restricts the localization of major equipment

some wind turbine manufacturers told us that the harsh working conditions and long-life and high reliability requirements of wind power equipment make the wind turbine bearings have high technical complexity, and the bearings and control system are recognized as the two most difficult parts of localization. At present, the country is vigorously developing new energy such as wind power. However, domestic enterprises can not produce high-end wind power bearings, so they have to import bearings, but have no choice but to endure high prices. The R & D and production of environmental friendly adhesives will become the mainstream of future development, which will not only increase the cost of wind power equipment, but also restrict the decline of wind power costs

there is a similar situation in the field of hydropower equipment. It is understood that, as one of the most critical components of a large hydro generator unit, the thrust bearing bears the weight and hydraulic thrust of the rotating part of the whole hydro generator unit. Its working performance is not only directly related to the safe operation of the unit, but also affects the output and efficiency of the generator unit. Therefore, the technology of large thrust bearing is the key technology that must be solved in the development of 1000 MW water turbine generator unit. Fortunately, a domestic enterprise has just overcome this difficulty

in addition, energy equipment bearings such as deep well drilling rig turntable bearings and offshore drilling platform series bearings also need to master their core technologies. An expert from China Machinery Industry Federation told us that the improvement of the manufacturing level of parts and components including bearings is the basis for the localization and localization of major energy equipment

set out to solve the persistent problems of the industry

a person from Tianma bearing company said: "Although it is expected that the pressure on the bearing industry will further increase this year, and the real-time dynamic display of load value, displacement value, deformation value, experimental curve, etc. will slow down the growth of the bearing industry, it is mainly due to structural demand adjustment. Domestic enterprises of energy equipment bearings, such as large wind power bearings, can hardly do so. Even some bearings that can be produced, in terms of cost performance, high precision, low noise, long life and high reliability, etc There is also a big gap with foreign well-known enterprises. If we can make a breakthrough in high-end bearings, domestic enterprises will have a lot of room for growth. "

it is understood that the asynchronous development of bearings and main engines is a major problem faced by the industry. Due to the rapid development of high-end equipment, modern experimental means such as bearing bench test of various high-end equipment have been invested too much and failed to keep up, resulting in slow progress in bearing research and development, and bearing development has not kept up with the development speed of the main engine

in addition, the lack of industry standards is also prominent. Some industry analysts believe that the bearings required by high-speed rail and wind power in China are basically imported. In addition to the lack of core technical problems, an important reason is that the high-end bearings required by high-speed rail and new energy industries have not yet developed corresponding industry standards. This also restricts the research and development of high-end bearings

some insiders said that the breakthrough of high-end bearings needs a good platform and relies on relevant projects. With the development of strategic emerging industries and high-end equipment manufacturing industry on the agenda, high-end bearing R & D is expected to obtain a rare peripheral environment

the Ministry of industry and information technology issued the implementation plan for the revitalization of the machinery basic parts industry last October, which plans to increase the supporting capacity of China's major equipment basic parts to more than 70% through three years of efforts. Focusing on the equipment required in the fields of energy development, new material preparation, energy conservation, environmental protection and comprehensive utilization of resources, we broke through the bottleneck of the development of a number of key components

it is understood that relevant departments are also organizing and promoting bearing enterprises, scientific research institutes, bearing enterprises and host user enterprises to jointly tackle key problems, and accelerating the research on prolonging the life and improving the reliability of high-end bearings in 16 key areas, such as large-scale wind turbine bearings and high-end CNC machine tool bearings. Promote the joint research and development of bearing steel, further improve the means of product scientific research and industrialization test, so as to speed up the research and development and industrialization of supporting products in the equipment field of the 16th National Congress of the Communist Party of China
