700 billion yuan investment in high-speed rail cake bearing equipment is monopolized by foreign capital

700 billion yuan investment in high-speed rail cake bearing equipment is monopolized by foreign capital "The bearings used in EMUs with a speed of more than 160 kilometers per hour are still 100% imported at present in China. However, according to our research and development speed, if all goes well, in the next two to three years, China-made high-speed rail bearings can also be truly supported."

On January 6, Wang Quanqing, secretary general of China Bearing Industry Association, said in an interview with the author that during the “12th Five-Year Plan” period, the key words of the domestic bearing industry will focus on independent innovation and tackle key technologies to achieve industrial upgrading and replace imports.

Two days ago, the Ministry of Railways Minister Liu Zhijun stated at the national railway work conference that this year the national railway infrastructure investment will be 700 billion yuan, 70 new projects will be arranged, and the total mileage of high-speed railway operations in China will exceed 13,000 kilometers, and Beijing will be established. The Shanghai High Speed ​​Rail will be opened in mid-June.

The sustainability of high-speed rail investment has been guaranteed, and the enthusiasm for a piece of related industries has continued to rise.

However, in the field of high-speed train bearings that are the basic components of high-speed rails, international giants such as SKF of Sweden, FAG of Germany, and NTN of Japan are firmly occupying the Chinese market. As soon as possible to solve the high-speed bearing R & D and application of the problem, this piece of "small and important" short board, has become a major task of China's bearing industry, whether for technical upgrading, or to share high-speed rail cake.

Short Board: High-end Insufficiency Compared to the fact that our country already has high-speed EMU technology with independent intellectual property rights, the domestic application of supporting bearings is still blank. This is a short board for the high-end equipment manufacturing industry.

On October 26, 2010, the landmark Shanghai-Hangzhou high-speed rail on the construction of China’s high-speed rail was officially opened. The highest speed of the CRH308A new generation high-speed train EMU with its own intellectual property rights was 416.6 kilometers, setting the world’s highest operating railway test speed. .

However, the bearing used on this "land flight" could not be produced in our country. Wang Quanqing told the author that the EMUs with a speed of more than 160 kilometers per hour and all high-speed rail bearings are all made with imported bearings, and the realization of domestic alternatives is bound to go through a long process.

Not only high-speed rail, wind power, machine tool spindle and other high-end bearings have always been the soft underbelly of the Chinese bearing industry, but also rely mainly on imports.

In 2009, the output of the bearing industry in China reached 10 billion sets, and the total output value has reached 90 billion yuan, ranking third in the world. There are 1750 enterprises above designated size, of which 5 have annual sales of more than 3 billion yuan, but the import and export deficit exceeds 800 million US dollars.

Wang Quanqing told the author that this situation has improved in 2010. "In 2010, the industry's sales increased by approximately 30%, and production increased by 13%, which exceeded the level before the financial crisis." "The year's exports increased by 50%, and the import deficit narrowed to between 500 million and 600 million U.S. dollars, but the imported bearings The composition is still moving towards the high end."

“The core technologies in this field are all overseas. Our industry has joined forces with common technology research and key technology public relations. It has already passed two five-year plans.” He said, “The key areas of the 16 major technical equipment proposed by the State Council are 15 All bearing-related, this is the key point."

In the "Implementation Plan for the Revitalization of the Mechanical Basic Components Industry" issued by the Ministry of Industry and Information Technology, bearings were also ranked first among the basic components. Bearing products of the seven projects were included in the implementation plan for 2011-2013.

Feast: Foreign Capitals In the total high-speed railway investment, the capacity of high-speed rail bearings is not too large. Experts estimate that the market exceeds 2 billion yuan. However, the gap in China's domestic products is already enough to provide a huge market space for foreign giants.

According to incomplete statistics, nearly 80% of the world's bearings are produced by 8 multinational companies, distributed in the United States, Japan, and Europe, and China has about 6,000 registered bearing companies. The total sales of the top ten bearing companies account for only Nearly 40% of the industry's share of the industry, the industry concentration is low.

On February 6, 2009, NSK Corporation of Japan cooperated with China South Locomotive (601766) Group and successfully signed the order of axlebox bearings of 30 groups of Wuhan-Guangzhou high-speed railway.

In March 2010, Sweden’s SKF announced that it would renew the four-year contract with the Chinese Ministry of Railways on the basis of the original four-year contract.

In October 2010, Japan’s NTN established the largest production base in China in Nanjing. In the first phase, it invested US$100 million to build a production base for bearings used in high-speed railways, subways, and wind power generation.

"Bearings account for only a small part of the entire vehicle configuration, but such projects as high-speed rail can not allow any slip. The most important bearing is reliability, safety is the first." January 6, SKF China Railway Business Unit Deputy General Manager Huang Zhi told the author.

At the same time, he also admitted that China's high-speed rail bearing market has left more room for foreign-invested companies due to the shortage of state-owned products, and is "sustainable until 2020."

According to the National Medium and Long-Term Railway Network Plan (Adjusted in 2008), by 2020, the mileage of China's high-speed railways will reach 18,000 kilometers. This figure is the total sum of high-speed railway mileages in Germany, Japan and France (6,000 kilometers). Three times. By 2012, the total mileage of China's high-speed railway will reach 13,000 kilometers, which will create 800 new demand for EMUs.

Catch-up: Self-Evaluation “From the perspective of the relevant state agencies, the import of high-speed rail bearings is still very strong. But for the domestic industry, we must always do everything possible to innovate.” Wang Quanqing said to the author.

In the first three years of the “Eleventh Five-Year Plan” only, 488 kinds of supporting bearings for 90 major equipments in 13 key areas of the country’s 16 key areas were developed. Among them, the wind turbine generator yaw pitch bearing, deep well ultra-deep well oil drilling machine bearing, heavy-load railway wagon bearing, YRT series CNC machine tool spindle bearings have been realized in China.

It is understood that under the support of the Ministry of Science and Technology's Science and Technology Support Program, Luoyang Axis Research (002046) Co., Ltd. (reformed enterprise of Luoyang Bearing Research Institute) will take the lead, and Luoyang LYC, Haxone, Chengdu Kehua and other enterprises as well as Henan Science and Technology. Universities such as universities and Chongqing University have carried out the research and development of high speed iron bearings with a speed of 350 kilometers per hour. The first samples have been developed and some performance tests have been conducted.

According to Wang Lushun, Chairman of Wazhou Group, after major breakthroughs in basic research, manufacturing processes and inspection processes, “through such design and manufacturing technology and product technology advancement, alternative imports will be achieved within three years.”

In October 2010, He Huawu, academician of the Chinese Academy of Engineering and chief engineer of the Ministry of Railways, pointed out at a forum that after the high-speed train with a speed of 380 kilometers per hour went offline, China had begun to develop a high-speed train system with a speed of 500 kilometers per hour. This means that the development and industrialization of high-end bearings need to be further pursued during the “12th Five-Year Plan” period.

In response, on January 6, an insider of the China South Locomotive Group stated to the reporter: “Under the global supply chain, it is normal for high-speed rails to carry out international procurement. But in the future, under the same conditions, we Of course, it is also willing to cooperate with domestic suppliers and purchase domestic products."
