"In the future, China's high-speed rail will use the 'China axis'!" During the national day, news came from Luoyang Bearing Factory (hereinafter referred to as "Luoxi") that the bearing product design, process research and sample manufacturing of high-speed railway bearing with speed of 250 km / h and 350 km / h have been completed. The product has passed 1.2 million km durability bench test, and the test results show that the bearing is in good condition and meets the standard requirements. Luoyang shaft has opened the technical channel for high-speed rail bearing development, and basically has the conditions for mass production of high-speed rail bearing.

　　Luoxi was the first batch of industrial enterprises in New China in 1954, which created many firsts in China's bearing industry. It has broken the monopoly of foreign technology for several times to speak for "China axis". On September 27, 1982, the bearings of b3-706 and b3-707 precision coordinate boring machine developed by Luoyang shaft won the National Gold Award. This is the only National Gold Award for high quality products in the bearing industry.
The spindle is the key component of the precision optical coordinate boring machine. The radial swing error of the bearing inner and outer sleeve should not exceed two thousandth of a millimeter, and the temperature rise of the bearing should not exceed 15 ℃ under the condition of high-speed operation. At that time, only a few Western countries could manufacture this kind of high-precision bearing.
The price of the two kinds of bearings developed and produced by Luoyang shaft is only 1 / 7 of that of foreign similar products. The successful development of these two kinds of bearings marks that China's high-precision bearing manufacturing technology has stepped into the world's advanced ran


　oday's Luo axis is still the gold lettered signboard of "China axis". Luoxi has the first batch of enterprise technology center recognized by the state and the only State Key Laboratory of bearing industry. Henan high-speed and heavy-duty bearing engineering technology research center and Henan bearing product quality supervision and inspection center are also located here, building a perfect bearing research and development experimental platform.
Xie Jinhui, deputy director of Luoxi technology center, said that at present, all nine types of bearings with various precision grades can be designed and manufactured, with more than 20000 kinds of varieties and specifications. It has core technologies such as aero-engine bearing, high-speed rail and rail transit vehicle bearing, special bearing for major equipment, etc. The company has been supporting bearing products for the Three Gorges water conservancy project, Shenzhou and Chang'e aerospace projects, the south to North Water Diversion Project and other national key projects.
