From the blockage of technology to the realization of technological overtaking, and even become the main supplier of products, such miracles often occur in China, and the product to be introduced to you today is a typical example.
Self-lubricating bearings are a very advanced technology, compared to traditional bearings it has many irreplaceable advantages, the current aviation, aerospace, military, science and technology fields need to use this key technology. However, in terms of this key component, China has relied on foreign imports for a long time in the past. However, the good news is that now China's bearing manufacturers have overcome this problem.
What are self-lubricating bearings
Presumably everyone has seen in daily life, at least know the existence of bearings, its role is mainly to reduce the friction of the parts that need to be rotated in the machinery, and can ensure the smooth operation of the machinery. Due to the high friction required, ordinary bearings must be used with emulsified oil, otherwise the bearings will be easily consumed by wear or damage.
However, despite the help of lubricating oil, bearings are still very easily damaged parts of mechanical components, because once the maintenance is not timely, or the lubricating oil leaks, the bearing is easily worn. The biggest advantage of self-lubricating bearings over conventional bearings is that they can work without the need for lubricating oil at all. And this bearing has better performance in terms of impact resistance, wear resistance, smoothness and so on.
Self-lubricating bearings through a special process, in the joint added solid lubrication material, so that the bearing does not have to constantly add lubricating oil to ensure the smoothness of the bearing, but also from the root cause to solve the situation of oil leakage, reduce the bearing failure rate. It is precisely because of so many advantages, so in many fields, self-lubrication has gradually replaced lubricating oil, especially in aviation, aerospace, military and other high-tech fields. However, due to the very complex production process of such parts, in the past many years, this part has basically been imported from abroad.
This technology was first in the hands of the United States, Japan, France, Germany and other countries. These countries have a deep heritage in the field of machinery manufacturing, not only started early, but also formed a very large industrial system, so in terms of technical strength, China has a very large gap with them. However, domestic bearing manufacturers have not given up, through unremitting efforts, and finally the manufacturing technology of self-lubricating bearings has now been conquered by domestic manufacturers.
Changsheng bearings overtake in curves
Speaking of bearings, we have to mention China's Changsheng Bearing, which is almost the strongest bearing manufacturer in China. In the traditional bearing business, Changsheng Bearing has reached the first strength in China. However, Changsheng Bearing was not proud and complacent, but began to move towards self-lubricating bearings with higher technical strength, and finally with long-term technical research, Changsheng Bearing became the first enterprise in China to master self-lubricating bearings.
Because the technology is not lagging behind foreign manufacturers, and the price occupies a great advantage, the self-lubricating bearings produced by Changsheng Bearing have quickly received widespread attention in the market as soon as they came out. Not only domestic manufacturers, but even many foreign manufacturers have begun to invest in Changsheng Bearing, which has also transformed China from a self-lubricating bearing importer into an important self-lubricating bearing exporter, which also allows the United States, Japan, France, Germany and other countries to re-examine China's technical strength in the field of bearing manufacturing.
At present, bmw, Volvo, Jaguar, Tesla, Audi, Volkswagen and other well-known car brands use most of the bearings from Changsheng bearings. Therefore, it is also time to re-examine China's bearing strength. After Changsheng Bearing made a historic breakthrough, domestic bearing manufacturers have caught up, and now many enterprises, including the Great Wall and Longxi Bearing, have mastered the manufacturing technology of self-lubricating bearings.
Even Longxi Bearing has mastered the more high-end self-lubricating spherical bearings, which is a technology widely used in the aerospace field, and has been used in the Shenzhou series of spacecraft, the Long March series of carrier rockets, and the Chinese space station. Now China has got rid of the embarrassment of relying on imported parts in this field, but has replaced all of them with domestic self-lubricating bearings, which is very gratifying.
summary
Perhaps in the eyes of many domestic netizens, many of China's technical aspects are not as good as foreign countries, and China is still subject to people in the field of machinery. It is undeniable that China's start in the field of machinery manufacturing is indeed much later than other countries, coupled with the fact that foreign countries have been eyeing China's development and are unwilling to share technology with China, so China's development is very difficult.
But Chinese scientists and enterprises have not given up technological breakthroughs, now in many fields we have achieved a counterattack, from scratch, from backward to leading, we have created one miracle after another, and self-lubricating bearings are just one of them, we should have confidence in China's technical strength, only by trusting Chinese enterprises, we can usher in better development.
Reverse output! Chinese enterprises broke the blockade of foreign self-lubricating spherical bearings and achieved overtaking in curves
Another technical blockade was broken by Chinese companies, and we could not only catch up, but also overtake in curves
