China's high iron special high-speed bearing r&d and application problem analysis

Countries already have independent intellectual property rights high speed emu technology reality, supporting bearing localization application is still blank, this in are trying to high-end equipment manufacturing industry is a place short plate. As a high iron base parts of high speed train bearing field, the Swedish SKF, Germany fag, Japan NTN and other international giant is firmly holds the Chinese market. JinMo traffic network CEO ROM the fai said that as soon as possible to solve the high speed bearing research and development and application of the problem, will this "small but important" for short board, has become a major task of Chinese bearing industry, whether to upgrade technology, or to share high iron cake.

All adopt imported bearing

In 2009, our country bearing industry output reached 10 billion sets, total output value has reached 90 billion yuan, the world's third largest. Enterprises above designated size 1750, annual sales of 3 billion yuan of above 5 home, but the import and export trade deficit of more than $800 million. JinMo traffic network CEO ROM the bright points out, more than 160 kilometers per hour above motor train unit, and form a complete set of high iron bearing imported bearing, realize domestic alternative certainly will experience a long process.

Our country is imported bearing constitute still to high-end development. "This field of core technology in all abroad, we joined in the industry common technology research, key technology of public relations, has been after two five-year plan." He said, "the state council put forward 16 major technical equipment, 15 key fields with bearing correlation, this is the key point. In previous work letter issued by the department of "machine foundation parts industry revitalization of the implementation plan", bearing also ranked base parts first, seven project bearing products are included in 2011-2013 years of implementation plan.
