The domestic bearing casting industry shoulders an important mission of the localization of higher equipment in our country. Under the guidance of the Twelfth Five-Year Plan, the domestic bearing casting industry has formulated a development plan. The policy of promoting the development of domestic mould industry by project and export is formulated.
The domestic bearing casting industry shoulders an important mission of the localization of higher equipment in our country. Under the guidance of the Twelfth Five-Year Plan, the domestic bearing casting industry has formulated a development plan. The policy of promoting the development of domestic mould industry by project and export is formulated.
It is reported that, driven by the development of rail transit, medical instruments, new energy, aerospace, automotive lightweight, rail transit and other fields, the level of bearing casting industry in China has been significantly improved. Bearing casting industry is advancing steadily in the traditional market while actively exploring emerging markets, and even marginal markets that were ignored in the past have been developed.
According to the relevant plan, during the 12th Five-Year Plan period, the construction of high-speed railway will usher in the peak. In 2011, the national railway infrastructure investment is planned to be 700 billion yuan, which provides a huge market opportunity for the entire high-speed railway equipment manufacturing enterprises. According to the 2008 Adjustment of the Medium and Long-term Railway Network Planning, 42 high-speed passenger lines will be built by 2012, with a total mileage of more than 13,000 km, which will create an additional demand for 800 EMU trains. By 2020, the length of high-speed railway will reach 18,000 km, providing a broad market space for high-speed rail bearings. In the next three years, China's high-speed rail bearing market will exceed 2 billion yuan. According to the survey, international giants such as Sweden's SKF, Germany's FAG and Japan's NTN firmly occupy the Chinese market in the field of high-speed train bearings, which are basic parts of high-speed rail.
Bearings are key components of major national technical equipment. At present, higher bearings such as car, high-speed rail, wind power and machine tool spindle supporting bearings have always been the soft ribs of China's bearing industry, which has long relied on imports. Because our bearing industry development can not keep up, pull the import of bearing. For example, in the great development of high-speed railway, the bearings for the EMU with an speed of more than 200 kilometers per hour are all imported, while the current domestic capacity can only meet about 160 kilometers of locomotive bearings.
Although a few domestic enterprises can manufacture bullet train bearings at the speed of 200 kilometers per hour, the relevant procurement departments will still use imported parts, and the prospects of the country's higher bearing field are worrying.
