Domestic bearing casting of high-end equipment industry shoulder the important mission of localization, under the guidance of the "Twelfth Five Year Plan", China's foundry industry has developed bearing industry development planning. Developed a project and export pulling two carriages of domestic mold industry development policy. Driven by the various fields rail transportation, medical equipment, new energy, aerospace, automotive lightweight, rail transportation and other development, China's foundry industry bearing significantly improved. Bearing foundry industry actively explore new markets while the traditional market stability department forward, even in the past ignored edge market has also been developed. According to the relevant planning, "Twelve Five" period, the construction of high-speed rail will usher in the peak, in 2011 the national railway infrastructure investment plan to 700 billion yuan for the entire high-speed rail equipment manufacturing enterprises to provide a huge market opportunity. According to "long-term railway network plan (2008 adjusted)" 2012 China will build 42 high-speed railway, the total mileage of more than 13,000 kilometers, which will form the new EMU needs 800 of 2020 our high-speed railway mileage will reach 18,000 km, for our high-speed rail bearings provide a broad market space. Bearing the next three years of high-speed rail market will be more than 20 billion. The survey found that as the field of high-speed trains bearing iron-based parts, but it is the Swedish SKF, German FAG, NTN, Japan and other international giants firmly occupy the Chinese market. The bearings are key components of the national major technical equipment, the current cars, high-speed rail, wind power, precision machine tool spindle bearings and other high-end bearing support has been the soft underbelly of China's bearing industry, over-reliance on imports. Due to the development of China's bearing industry can not keep up, the strong pull of imported bearings. As in the great development of high-speed railway, the speed of 200 km above the EMU bearing all imported and domestic currently able to meet only about 160 kilometers locomotive bearing. Although a small portion of domestic manufacturing enterprises to 200 kilometers per hour EMU level bearing, but still related to the purchasing department will use imported parts, bearing the field of high-end prospects bleak.
