Why the most high-end bearing need to rely on imports?

In this world, in addition to earth, who need rotation, all need bearings. Bearing, almost exists in every corner of our life. Bearing is always everywhere. Bearings have high technical content, can be used as a measure of a country the important standard of science and technology, industrial power. In today's world of science and technology, industrial powers without exception is bearing research and development, manufacturing power. Rather than the industrial powers, industrial in our country is an important performance bearing industry is big but not strong. Bearing production in our country the third largest in the world but a large number of high-end bearing imports more than 70% of the world bearing market, dominated by ten large multinational bearing group company, including a Swedish company, five Japanese companies, two German companies, two American companies. Not a Chinese company. High-end bearing the research and development, manufacture and sales of basically by the four bearings giant American iron Ken, Japan NSK, SKF of Sweden, Germany schaeffler ( FAG) The monopoly. Bearing industry of high-end market monopoly by the enterprise, while the low-standard market mainly concentrated in China. And of the ten biggest such as our country wazhou bearing enterprises, sales of just 24 of the industry. 7%, while the former 30 production concentration is only 37. 4%. There is no doubt China is super bearing power. As early as 2014, China has reached 19. 6 billion sets of bearings production, one of the world's third. Our bearing production can support the fingertips gyro that decompression toys, production of large accounts for one 5 of the world. China produces the minimum bearing diameter 0. 6 mm, the biggest 11 meters in diameter, in dungeons, everywhere. Yet China's bearing industry like many industrial sectors, large capacity, technology level of medium, a few core areas of breakthrough in the west block, a large number of high-end product but still have to rely on imports. The difference between domestic bearings and import bearings have how old? Our bearings and other mechanical products, cutting-edge products, reliability, life, etc. , has a considerable gap with the western developed countries. In high-speed bearing, the domestic makers axle box used in the production of the emu, bearing brands from Europe, Japan, China's own production of vacuum degassed bearing steel, quality stability and fatigue life, all with foreign high quality vacuum degassing steel there is a certain gap. As a mechanical products, bearing cannot be opportunistic basic components. Bearing performance mainly depends on material properties and processing technology. As the world's first steel superpower, although we in the majority of steel products has been rolling around the world, but in high strength, high wear resistance of bearing steel smelting, still significantly lagged behind Europe and the United States and Japan. In high precision machining gap is also significant. Why couldn't we make high-end bearing? High-end bearing imports, why do we make not to come out? The biggest problem on the material, there is no good steel, will never make a high-end bearing. How important is in high-end steel bearing? In automobile engine bearing, for example. Engine bearing has been working in the 'purgatory' - — It should not only with tens of thousands of RPM speed high speed for a long time, but also under various forms of extrusion stress, friction and ultra high temperature. The accuracy, performance, life and reliability of the bearing is put forward very high requirements, and determine which of the four key factors, lies in its material. High-end bearing steel, can be very good to solve these problems, but not high-end steel, even with good bearing manufacture craft can not build a high-end bearing. What is a high-end steel? 'PPM' is the unit of oxygen content in steel, refers to the hundred million or a few parts per million. In general, in the steel industry, 8 PPM steel belongs to good steel; 5 PPM steel belongs to high-end steel, high-end bearing is needed. High-end research and development, manufacture and sales of the bearing steel is basically the world bearing giant iron, Ken, Sweden SKF monopoly in the United States. A few years ago, they set up a base in yantai, shandong province, jinan, China purchasing low-end material, use their core technology to make high-end bearing, with ten times the price to sell to the Chinese market. Is to celebrate the problem was finally conquered China, in July 2018, the first king of west special steel high-end rare earth bearing steel production line, the technical performance reached the international advanced level, product quality than the United States, the European standards. West king special steel with the Chinese Academy of Sciences jointly produce the high-end rare earth metal bearing steel is to solve the problem of 'their' high-end bearing steel technology. International top ten bearing factory are belong to the west. Now that China is not going to succumb to americans dominate the international order, it must face to be in the key areas of their risk. Chip, so, of course, high-end bearing. Only we increase in high-end bearing developed in terms of manpower, financial and material resources, China can be achieved by bearing the fundamental shift of power to the bearing power.
