The domestic metal bearing casting industry shoulders the important mission of the localization of my country's high-end equipment. Under the guidance of the 'Twelfth Five-Year Plan　　 At present, our country should drive the development of the domestic mold industry with projects and exports. Driven by the development of various fields such as rail transit, medical equipment, new energy, aerospace, automobile lightweight, and rail transit, the level of my country's bearing casting industry has been significantly improved. The bearing foundry industry is actively exploring emerging markets while steadily advancing in the traditional markets, and even marginal markets that have been neglected in the past have also been developed.　　 According to relevant plans, during the 'Twelfth Five-Year Plan' period, high-speed rail will usher in the construction peak. In 2011, the national railway planned infrastructure investment of 700 billion yuan, which provides huge market opportunities for the entire high-speed rail equipment manufacturing enterprise. According to the 'Medium and Long-term Railway Network Planning Adjustment in 2008In the next three years, my country's high-speed rail bearing market will exceed 2 billion yuan.　　 As the basic parts of high-speed rail in the field of high-speed train bearings, international giants such as Sweden's SKF, Germany's FAG, and Japan's NTN firmly occupy the Chinese market. Although a small number of domestic companies can manufacture EMU bearings with a speed of 200 kilometers per hour, the relevant procurement departments will still use imported components. The prospects of my country's high-end bearing field are worrying.
