China Bearing Industry Association revealed that Chinas bearing industry in 2010 sales revenue and profit growth of more than three. However, China Bearing Industry Association, the relevant responsible person said that in 2011 the pressure will further increase the bearing industry, bearing industry growth will be slowed, bearing enterprises should pay attention to. Bearing enterprises responsible person told the reporter, now energy equipment, as the representative of the high-end equipment manufacturing coincided with the peak of development, if can leveraging energy equipment and other downstream industries to achieve technological breakthroughs in high-end bearings, greatly enhance the level of development of bearing industry.
12th Five-Year to enter the high-end bearing
According to China bearing industry association data, the bearing industry in 2010 the main business income will exceed 100 billion yuan mark, reaching 120 billion yuan, the growth rate will reach 30%. Among them, a large increase in demand for small bearings, bearing production is expected to reach 15 billion units throughout the year, an increase of 36.36%.
It is understood, in 2010 the national bearing industry leading enterprises R & D the 13 key areas in 106 kinds of major technology and equipment of the supporting bearing 528, new sales income of 92 billion yuan, the product reached the level of similar foreign products. Including reached the international advanced level of the wind turbine yaw, pitch bearings, nuclear power plant secondary pump bearing, high power locomotive bearing, ultra precision of Sendzimir mill bearing and continuous casting production line segment bearings, and the gradual implementation of the industrialization.
China Bearing Industry Association official said, "Twelfth Five Year Plan" period, focus on the development of is greatly improve product quality and technical level, increase the market share of key host supporting bearings, to enter the high-end market in the high-speed railway passenger car bearing, high power wind power bearing, precision CNC machine tool main shaft bearing, large aircraft bearing bearing.
Supporting domestic production of energy equipment
Wazhou group technical staff told reporters that the bearing is the equipment manufacturing industry is an important and critical infrastructure components, directly determines the major equipment and the host of product performance, the level of quality and reliability, but Chinas high-end bearing such as high speed and high precision machine tool bearings, power supporting bearings currently rely mainly on imports.
An industry source to reporters cited an example, although China has independent intellectual property rights EMU technology, but the application is still supporting the localization of the bearing blank. At present, Chinas high-speed bearings can only meet the 150-180 km of the EMU, while the European and American countries high-speed rail bearings to meet the needs of 350-400 km per hour. So, at present, more than 200 kilometers per hour for the motor car group supporting high-speed rail bearing basically rely on imports.
In the field of energy equipment, one of the key parts of bearing but also the constraints of major equipment.
Wind turbine manufacturers told reporters that the use of wind power equipment of poor working conditions and long life and high reliability requirements, make wind power bearing has high technical complexity, bearings, control system is recognized domestic difficulty biggest two parts. Now the country to vigorously develop wind power and other new energy sources, but domestic enterprises unable to produce high-end wind power bearing, had to import bearings, helpless endure high prices, increased the cost of wind power equipment, also restricts the decline in the cost of wind power.
Chinas bearing industry is in urgent need of independent innovation to achieve technical breakthrough upgrade release time: 2011-03-03 source: China energy news report in the field of water and electricity equipment also has a similar situation. It is understood, as one of the large hydroelectric generating unit is the key part of the thrust bearing under rotational part weight and water thrust of the hydrogenerator unit, its performance not only directly related to the unit can run safely, but also affect the turbine output and efficiency. Therefore, the large thrust bearing technology is the key technology that must be solved in the development of the 1000 MW turbine generator set. Fortunately, the domestic enterprise has just overcome this one soon.
In addition, deep drilling rig turntable bearings, offshore drilling platform series bearings and other energy equipment bearings also need to master the core technology. China Machinery Industry Association, an expert told reporters, including bearings, including the level of parts manufacturing is the basis for major energy equipment to achieve localization and autonomy.
To solve the industry ills
Tianma Bearing Co., Ltd., a person to reporters said: "although it is expected that bearing industry this year will further increase pressure, bearing industry growth will slow somewhat, but is mainly structural adjustment needs, like energy equipment bearing of large-scale wind power bearing of domestic enterprises basically do not. Even if some of the production of bearings, in cost-effective, high precision, low noise, long life and high reliability and other aspects of well-known enterprises with foreign countries there is a big gap. If you can break through the high-end bearings, domestic enterprises will have a lot of room for growth."
It is understood that the development of bearings and the host is not synchronized with the industry is facing a major problem. Due to the rapid development of high-end equipment, all kinds of high-end equipment bearing bench test and other modern experimental means to put too much and did not keep up, leading to the slow development of bearing R & D, bearing development did not keep up with the development speed of the host.
In addition, the problem is also very prominent industry standards. Some industry analysts believe that at present Chinas high-speed rail, wind power and other demand bearing almost completely dependent on imports, in addition to the lack of core technology, an important reason is the demand for high-speed rail, new energy industry of high-end bearings to develop corresponding industry standards have not yet. It also restricts the development of high-end bearings.
Insiders said that the breakthrough needs of high-end bearings have a good platform, relying on related projects. With the development of strategic emerging industries and high-end equipment manufacturing industry
