So why is imported Porsche so expensive?

German bearings and domestic bearings are not summarized by the word "poor". As the old saying in China goes, you get what you pay for, and the German bearing and the domestic bearing itself are not a price, and the quality must be equal. If the quality of the ratio is the same, it should be a comparison with the same model parameters at the same price, rather than a comparison with other variables that remain unchanged.
I feel that one of the German bearing brands, WST bearing (Wosted) is cost-effective. Our company has been using it since May 16, and I feel that the quality is excellent.

Let's put it this way, China's bearing industry.

Or the materials can't keep up, foreign countries won't transfer technology to you, domestic technology can't keep up, plus the irrationality of domestic education, etc.
-
Chinese workers lack the spirit of dedication and love for their work, and Chinese enterprises look at money and do not pay attention to product research and development.

Bearing technology available for indefinite use at 160,000r min. High-end bearing technology is applied in various fields such as spacecraft, aircraft, rockets, atomic energy equipment, instrumentation, vehicles, ships, etc.

Domestic bearing three big family, ZWZ, Luo axis, Harbin axis, to talk about the characteristics of each has its own merits, but ZWZ is China's first bearing factory (established in 1938) is also the largest bearing manufacturing and sales enterprises in China, known as the "boss of the watts", ZWZ is the leading enterprise in China's bearing industry, on behalf of China's bearing national industrial development level, ZWZ is the only domestic bearing industry to obtain China's well-known trademarks, brand-name products, inspection-free products, national export recommended products. The company has won many honors, including independent intellectual property rights, national, provincial, and ministerial awards. The corporate reputation is AAA.
There are also the Group's low-noise ball bearings;
cylindrical roller bearings of Tianma Bearing Company;
Wanxiang Group, Chongqing Yangtze River's automotive wheel bearings;
Tapered bearings of Xiangyang Automobile Bearing Company.
However, the quality of domestic bearings can only be said to be not absolutely good, only relatively good, and the quality level of different companies in different bearing fields is not the same. But overall, there is still a certain distance compared with foreign countries.

The development of domestic bearings to the present product quality has been able to replace imported bearings, but in some special areas can not completely replace imports, you asked the quality of the domestic bearings I recommend a few brands to you, I hope to help you:
1.Harbin shaft - mainly in the small bearings to do better, especially machine tool spindle bearings, it is the first manufacturer in the country to produce machine tool spindle bearings, but now the market circulation is a part of the fake, fake quality is definitely not good, so you have to buy from the regular Harbin shaft sales office.
2.Luo shaft - Luo shaft is mainly in large bearings to do a better job.
3.ZWZ - ZWZ has now introduced SKF production technology, which has strict requirements for the quality of bearing products, and it has done a good job in tapered roller and spherical roller bearings.
4.C&U - C&U Bearing is now doing a better job in deep groove ball bearings in motors, and can replace imported brands such as NSK.
5.Universal – It is very good at universal joint bearings.
6.Tianma - Tianma has developed rapidly in recent years, especially in railway bearings.
When choosing a bearing brand, it mainly depends on the type of bearing you want, and now there are many types produced by large manufacturers, but each one has its own flagship products, so don't be blind when choosing.
Hope it helps!!

Hello, this distinction is generally only available to people in the industry, but one thing is very important.
Second: ask the other party to issue a quality assurance certificate, such as a one-month replacement, one year of quality assurance, so that you can avoid buying fake and shoddy bearings, because counterfeit bearings will be broken in a few days.
Three: to buy imported bearings, you need to choose a better brand, but their ** is relatively high, such as: FAG, SKF, etc.
