The manufacture of bearings has a long history in China, and the structure of bearings has long been recorded in ancient Chinese books. Bearing is an important basic component of all kinds of mechanical equipment. Its precision, performance, life and reliability play a decisive role in the precision, performance, life and reliability of the main engine.


From the middle of last century to now, China has to say that the bearing manufacturing industry has a strong momentum. At present, there are more than 1400 bearing enterprises in China, with more than 300000 employees.


However, in addition to a few well-known brands such as ha, WA, Luo and humanism, other domestic brands are still in an embarrassing situation of not being recognized. With the landing of SKF, FAG and NSK in the domestic market, the price difference with domestic brands is 10 times.


What causes this?


On the current situation of China's bearing industry, some people summed up these two points.


1. A lot of capacity, overproduction


2. In terms of technology, the vast majority of enterprises have obvious shortcomings, that is, if the bearing industry needs 18 kinds of martial arts cities,


There will be 134 small bearing enterprises in China, and the last key ones will be in serious shortage. This is the gap with foreign enterprises. Generally speaking, domestic enterprises that can do OEM have been able to control all key production links, but they have no ability to develop positively. In short, they are just processing plants.


It has been compared that the biggest gap between domestic bearings and SKF lies in product stability. The basic research on bearings in China, such as the structure after forging and the distribution of forging ratio, is lacking. There are many problems in the production process of bearings, such as raw materials, heat treatment and grinding, without in-depth research, so the trial production process can only be tasted. In the details of the production process, the gap with the imported bearings gradually widened.


Secondly, the lack of investment in bearing technology is also an important reason. Then why not increase the investment? It's simple. There's no money. This is also due to China's unique proliferation of counterfeit goods.


Due to the low threshold of bearing technology, small workshop type bearing factories are blooming all over the coast. The generation of Liaocheng tobacco shops are almost all small family workshops, and they can't see the difference. In addition, the OEM and counterfeiting have a great impact on these large factories, especially the state-owned enterprises. As a result, the competition pressure of general bearings is huge, and there is little profit for regular large factories to produce these general bearings. If there is no profit, there will be no funds to buy high-precision instruments, and there will be no way to promote the research of high-end products. In the long run, there will be a vicious circle.


In recent years, with the public security departments cracking down on counterfeit bearings, people's anti-counterfeiting awareness has gradually improved, and a large number of small workshop bearing factories have closed down. More transparent and convenient bearing trade also makes those fake bearings nowhere to hide. To a certain extent, it protects the basic rights and interests of the bearing people, and promotes the development of domestic bearings to be more systematic and perfect


China's wind power bearing has been the first to go abroad and occupy a place in the international market. This also gives the bearings great confidence. For domestic bearings, we should be full of confidence. They are expected to be "made in China".
