Metro vehicle axle box bearings achieve localization significant

The pagoda Industries (formerly Northwest Bearing) and the Beijing subway operating company Metro Operation Technology R & D Center jointly developed the "localization subway axle box bearings", was held in China Communications and Transportation Association Urban Rail Transit Committee and China Bearing Industry Association "Domestic of metro vehicle axle box bearings Development and evaluation of pilot projects run "passenger operations expert review will be identified as" the leading domestic level, can replace imported products. "

Not long before (September), the pagoda pagoda Ningxia Petrochemical Technology Industrial Company, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences to develop "high-speed rail bearing grease" is also detected by the statutory National Key Laboratory of solid lubrication, have been identified to "meet and exceed the performance of similar foreign products, to fill gaps in the domestic industry." Pagoda Industries chairman Zhang Lizhong accept the "Securities Daily" reporters, said, "After these two research successes, for enterprise development direction and positioning has a very important significance to the future, the company will continue to increase investment in science, to attract high-end talent, develop more scientific and technological achievements.

To achieve localization

It is understood that the pagoda Industries is October 17 when the company "50th anniversary" anniversary, announced the joint development of these two products are research experts through messages and testing. Zhang Lizhong briefed reporters on metro vehicle axle box bearings are a key rail transportation equipment, basic parts, and bearing quality is rail transportation market development bottleneck. All along, Japan, Sweden, Germany and other countries of the bearings business monopoly bearing technology, making the country the metro vehicle axle box bearing long-term dependence on imported products.

After "In order to achieve localization and axle box bearing import substitution. Pagoda Industry from 2008 to begin research and development. Design beginning in accordance with international high level of reliability design." Zhang Lizhong introduced ", the company commissioned a professional institutes related experiments. In the product fully meet the test requirements of the situation, the depth of cooperation with the Beijing Subway Company vehicle technology research and development center, to discuss the localization of imported metro axlebox bearing test driving matters, the two sides developed a detailed experimental programs and emergency response plans. after full argument and reasonable arrangement, Beijing Subway Operation Corporation actively coordinate various units, in July 23, 2014 was 1,000 km run load test loading and overloading experiment a success. November 24, Beijing Subway Operation Total Companies invite domestic experts, an expert team of metro vehicle axle box bearing loading experiments carried out mid-identification, agreed that the pagoda Industrial developed urban rail vehicle axle box of the data to meet the national standards in 2014 December 1 Day, the 8th in Beijing subway line for the 100,000 kilometers and passenger network running through online tracking and detection, before the National Day this year, the experiment a success.
