Chinese-Made bearings started late, but have developed rapidly. Some categories of bearings have reached the international leading level (such as shield machine main bearings, high-speed EMU bearings, magnetic levitation bearings, etc.), and even in some specific fields, such as rocket engine bearing technology and satellite long-life bearing technology, they have been included in the "Export Prohibition Catalogue", which shows that as long as there is external force driving, it is not a problem for bearings to lead the world in a short period of time.
At present, the main problems affecting the quality of domestic bearings are bearing steel and heat treatment, which is also the main means for the United States and the West to "choke" my country's bearing industry during the trade war.
On September 16, 2020, one day after Huawei was "cut off from chips", Bai Chunli, then president of the Chinese Academy of Sciences, said at a press conference of the State Council Information Office that the list of American necks would be turned into a list of scientific research tasks for layout, such as aviation tires, bearing steel, lithography machines, and some key core technologies and key raw materials.
We can see that in the past five years, China has made great progress in the field of bearing steel, and there are even some technological innovations that make people say "wow", such as the "hashed neutron source bearing identification technology" developed by the Institute of High Energy Physics of the Chinese Academy of Sciences, and the new quenching process innovated by China Railway Construction Heavy Industry from the "covering soil and burning blade" manufacturing process of the "Sword of Goujian, King of Yue", etc., all of which demonstrate the earth-shaking changes in domestic bearings in recent years.
The future of domestic bearings is promising. I believe that with the development of time and the advancement of technology, it will no longer be just an unattainable dream for domestic bearings to surpass imported bearings.
