China's wind turbine bearings supporting the development and industrialization issues to be addressed
(A) the wind power industry has a huge real market and broad market prospects, but the wind power industry is capital-intensive and technology-intensive high-risk industries. The face of the wind power industry, the rapid development of the situation and the huge market demand, China's bearing industry formed a wind power Slewing bearing investment. However, in stock and investment boom behind the lack of market for wind power bearing depth analysis of the market for wind power bearing huge investment risk, market risk and technical risks underestimated. In this regard, we have a further bearing industry enterprises issued a warning to prevent the emergence of wind power bearing irrational investment. Bearing enterprises in the wind power bearing for big investment, be sure to the world and China's wind power industry total size, actual and potential domestic and foreign wind power bearing market, competitors may occupy the market share, the companies have much market competitive space, through the efforts of the enterprise can enter the advantages of wind power equipment manufacturing enterprises of the industry chain, etc., for serious and sober analysis. Those who lack technical reserves, there is no strong technical support for enterprises, involved in wind power bearing market, we must be careful.
(Two) Currently, wind power bearing R & D and industrialization is very uneven. Since yaw bearings and pitch bearings single set of sales in high value-added, technology is relatively easy to enter the field of wind power bearing the manufacturers are concentrating on the beginning of the yaw bearings and pitch bearings, bearing several major domestic manufacturers has formed the production capacity of the planning objectives and a rough estimate of about 40,000 units, has far exceeded the needs of the domestic market. However, spindle bearings, generator bearings and gearbox bearings in the development and industrialization of inadequate attention. Especially gearbox bearings, bearings made now almost none to enter this field. Only a few samples of competitive enterprises started business in the host or components installed for testing. Wind power equipment manufacturers in order to host and component manufacturing organization conducive to the production and quality control, the need to Taiwan allotments bearing manufacturers supply bearings. Therefore, interested in market share in the wind power bearing a place of business, not only to the development, production yaw, pitch bearings, but also to the development, production gearbox bearings, spindle bearings and generator bearings, and strive to become Taiwan allotments available, into the wind power equipment OEMs and parts plant (generator factory accelerator manufacturer) industrial chain.
