Which company’s bearings are the best for building aircraft carriers?

How great it is that they are domestically produced; many components on Shenzhou VII were made in China

As long as there is a need, the Chinese can manufacture anything; if China can build things that go into the sky, it certainly can build those that go into the sea as well.

Let’s work together! To make efforts toward the early liberation of Taiwan, China’s aircraft carriers will surely use domestic components. Hehe

In terms of quality, German bearings are the best.

China’s top-tier technology is definitely excellent; it’s just that the cost of making it accessible to everyone is too high； Shipbuilding must use domestic parts

The quality of bearings produced in our country is also quite good. Personally, I think the products made by Harbin Bearing Factory are excellent. Why do we have to use foreign ones? Just as was said on the second floor, didn’t we also develop the Shenzhou series of spacecraft independently? *As the wise man said, “We must rely on our own efforts and work hard”; through our own endeavors, we can also protect our national industry!

Most are imported, with a small portion being domestically produced

We should have confidence in China’s capabilities – can’t we use other people’s technology to develop our own products? If China builds aircraft carriers, the world will surely be shocked; let’s wait on it with pride!

I believe that the bearings used in aircraft carriers and those used in the Shenzhou spacecraft are based on two different concepts. The Shenzhou spacecraft operates in different conditions; it requires high reliability, but lower demands in terms of service life and load-bearing capacity. Moreover, the components used are small and can be easily obtained in a laboratory setting. In contrast, aircraft carriers require extremely high load-bearing capacities and long service lives, and since the components involved are huge, maintenance becomes very difficult. Therefore, the performance and technical requirements for such applications must be at the highest level. There are good domestic products available, but foreign products are still preferred for large-scale equipment. What would happen if, during an intense battle, it was reported that the bearings had failed?

No matter whose product it is, as long as the quality is fine, what do we have to worry about?

Choose domestic bearings; domestic brands need to live up to expectations! By ensuring good control over material purity and processing quality, as a technical research project, I believe there are surely many doctoral theses lying unused that could be utilized. These days, many fans use foreign bearings; domestic brands need to step up their game!

Domestic bearings are of high quality; manufacturers such as Luoyang Bearing and Wafangdian Bearing are established firms with excellent technical capabilities. I am optimistic about Luoyang’s bearings.

Let me share my feelings; please don’t attack me with insults! The bearing industry is a highly technology-intensive sector; high standards are required in terms of machining precision, heat treatment, and materials, and this is especially true for electromagnetic bearings and high-speed bearings used in bearings. We don’t go into detail about how manufacturers process and control these bearings, but from the perspective of usage, the difference is evident: when installing SKF or NSK bearings, no special skills are required, whereas with domestic bearings, one needs to be highly skilled in order to avoid problems ； The differences in usage are even more significant. For bearings used abroad, as well as in the equipment we send overseas, the environmental conditions and temperatures are extremely harsh, yet there are no problems with their performance. In some domestic projects, however, when domestic bearings are used, various issues arise; their lifespan, noise levels, and vibration characteristics are not comparable to those of imported bearings. This is just the field I’m familiar with, and it seems that our domestic industries need to develop at a faster pace. As long as our products work well, we prefer to use those made **by us own country – after all, they belong to our own nation; who would want to use foreign products?

Of course, use ones from your own country; you can’t use American bearings to build something in the United States, otherwise you won’t be able to find the necessary components.

It’s definitely not possible to use bearings made in the United States; instead, those made in Europe such as in Germany, or in other countries, can be used. It’s similar to weapons – we can also choose other high-quality weapons. Moreover, these bearings are extremely important components on ships. There are good domestic products as well, but they are not on the same level as those of world-class quality. If an aircraft carrier requires a long time for maintenance, it essentially means increased costs and reduced efficiency, which makes it less cost-effective in the end.

Key defense technologies must be domestically produced; otherwise, if the bearings break and foreign companies refuse to sell you replacement parts due to diplomatic issues or war, won’t that put us in a difficult situation? Furthermore, the quality of domestic bearings is now quite good; once the Chinese people put in serious effort, there is nothing they cannot accomplish

I agree with what was said in point 13#; Luoyang Bearing is undoubtedly one of the best in China. So I am also optimistic about Luozhou Bearing

China’s aircraft carriers need to draw on the strengths of others while addressing its own weaknesses; quality is important, and it must be top-notch. Don’t hide your illnesses or avoid seeking medical treatment; progress is what truly matters.

Of course, domestic products should be used. With so many bearing manufacturers in the country, it shouldn’t be a problem to produce some specialized bearings. In the field of national defense and military industry, cost considerations aren’t always important; good quality is all that matters
