Which type of bearing is in high demand now?

Now it's the No. 5 bearing, and the demand is relatively high, because now it's not a large machine.

Now take which type of bearing is in high demand, I think of course the demand for L-size bearings should be relatively high, and the use of many large vehicles is very high, and now there are still a lot of large transport vehicles.

The type with the largest bearing load is generally tapered roller bearing, although other shaft types can also be used according to requirements, such as angular contact bearings.

Generally, the demand for other bearings is not high, so the demand for deep groove ball bearings should be relatively high.

Generally, the demand for bearings for shoes Xiaomi and Huawei is relatively high, and its models are particularly wide.

Answer: Wind power bearings now have the most development potential! Automobile bearings are selling well! There is a market for train bearings.

If the demand for bearings is high now, it is basically the kind of left side of about two meters that has a high usage rate.

Now the largest demand for bearings should be some of Stanford's shaft diameter bearings.

Now the demand for bearing models is generally not too high, because the requirements for bearings have increased, and the demand for bearings has decreased, so it has not been so high.

The demand for bearings is good, he is in equal consumption, he is in a different place, the need for bearings, size and quality of bearings are good.

Now I think that the demand for each type of bearing is quite high, and now it is really in demand.

Now which type of bearing is really very beautiful, the dog has a high amount of loyalty, and that kind of loyalty is a very rare, and it can only be used in the way of a precision instrument.

Chen Zhou's words are okay, I don't think there is much difference. It depends on the individual.

Which type of bearing is in high demand now? Well, this bearing with high demand is the one that is currently on the market and has a relatively large amount of access.

Which type of bearing is required in high quantity now? Now there are many bearings that need to be high, because now the technology is very developed, and some things can be done.

Now which type of bearing is in high demand, this is difficult to say, what model you need to use what model.

What now? The demand for several types of bearings is very high, because the demand for social demand can be greater and greater.

There are still a lot of bearings, and if the amount of things that are required is high, I think this is also because there is.

Personally, I think that on the railway, the requirements for bearings in power plants are relatively high. High precision, high speed, and in some harsh environments there are requirements for bearing wear resistance and friction.

It should be the kind of requirement that the speed is very high and the bearing temperature is very high.

Now which type of bearing is in high demand, you can go to the store to buy this, ask clearly, you can also check it online.

That type of bearing is in high demand, I think, like the bearing, this piece basically has a corresponding one, that is, a method for it.

Hello! Which type of bearing type requires more quantity, generally speaking, people who work in hardware stores should be more clear. Of course, there will be different needs in different places.

If you need to pump the bearing, you need to go to the physical store and look at it yourself, and then see if it is bad or bad.

Now which model causes a little noise, higher than according to the demand of that market to shop around to see the match.

It depends on which kind of equipment you are currently using, and the consumption of the parts related to it is greater.

Now which type of bearing is in high demand, you have to check some introductions about this bearing.

The demand for models is still relatively high, involving three aspects.

Now the bearing demand is high for models, you go to check the bearing, the sales volume and its classification data in the last two years.

Now the main domestic bearing production area is mainly in Ningbo, such as HCH bearing is very good, Cixi is also a very large output bearing area, which has always had the reputation of the kingdom of micro bearings. The quality of domestic bearings is very good, mainly Harbin bearings, Wafangdian bearings, Luoyang bearings three major bearing manufacturers, another rising star is the people-oriented bearing, the development of people-oriented bearings is quite fast! ! The quality is also top-notch!!

China's largest bearing production base is in Shandong Yandian.

What is the purpose of your investigation?

I've done bearing exports. I'll say a few words, to be simple.

After more than half a century of development since the founding of the People's Republic of China, China's bearing industry has experienced from scratch to make socks.

At present, China's bearing industry has formed a three-legged situation of state-owned enterprises, foreign-invested enterprises and private enterprises. Large state-owned enterprises such as Havalo continue to play the role of backbone, and private enterprises have sprung up and played flexibly.

At present, the spine is excited, and the bearing industry in China is facing problems.

The product quality is still low, the scientific and technological content, and the added value is not high, especially in some major equipment fields, which are still largely dependent on imports, but there has been some progress in recent years. For example, ZWZ has its own railway bearing production line and automobile bearing production line.

China's Hu Zheng bearing brand advantage is weak, except for a few brands are still loud, most of the rest are doing OEM production.

At present, imported bearings still occupy a large share in the market. In addition, international bearing multinational companies are vying to invest in China and speed up the localization of procurement, and our original advantages have weakened.

To say the bearing industry, the bearing is the national economy, that is, the basic industry, any place where there is mechanical rotation can be used bearings, the development of the industry is very critical. There are countless places where bearings are used.

1) The accuracy of the oil-impregnated bearing is low, and the service life is 20,000 hours, total: 834 days, and the annual bearing is in contact with the relative motion line of the shaft. The friction of operation is large. The vacuum impregnation method is used to store oil in the oil hole of the inner diameter surface of the bearing, and the oil film lubrication is formed by friction and heat generation during operation.

1) The accuracy of the oil-impregnated bearing is low, and the service life is 20,000 hours, total: 834 days, and the annual bearing is in contact with the relative motion line of the shaft. The friction of operation is large.

The vacuum impregnation method is used to store oil in the oil hole of the inner diameter of the bearing, and the oil film is formed through the friction and heat generation of the operation. The celery fan is fixed vertically, which is better to use.

2) The accuracy of single ball bearings is secondary. The service life is 30,000 hours, total: 1,250 days, and there are annual lines and point contacts.

Running friction is secondary. The use method has the characteristics of oil-impregnated bearings and double ball bearings, and the load of the running lap balance excavation mainly falls on the balls at the front end, while the copper synthesis at the rear end provides the fulcrum effect, and adjusts the centroid according to the positioning of the balls. The fan is fixed in a vertical direction, which is better for use.

3) The maximum service life of double ball bearings is 50,000 hours, total: 2,084 days, and the relative movement of the bearing and the shaft is point contact. Less friction in motion.

The balls inside the bearing are rotated with lubricating grease under the positioning of the retainer. The fan can be fixed in any direction.

Ball screws, like rolling bearings, wear and tear will accelerate when foreign matter or moisture is mixed in, and in severe cases, it can even lead to breakage. In order to improve the axial stiffness of the support, it is also important to select the appropriate rolling bearing. At present, there are two main combinations in China.

One is to use a combination of radial bearing and tapered bearing, although its structure is simple, but the axial stiffness is insufficient. The other is to use the thrust bearing or the radial thrust bearing and the radial bearing combined, and its axial stiffness has been improved, but the frictional resistance and heat generation of the bearing have been increased and the structural size of the bearing support has been increased.

The requirements of the ball screw pair for the rolling bearings are the same as the requirements for the rolling bearings of the spindle and the transmission shaft, and the rolling bearings should have sufficient accuracy and fatigue life. But the difference is also prominent, the ball screw mainly bears axial load, except for the screw weight, generally no radial load.

Therefore, the axial accuracy and axial stiffness of ball screw auxiliary rolling bearings are required. The feed system requires flexible movement and a sensitive response to small displacements (small rotation angles of the lead screw). Therefore, the frictional moment of the bearing should be kept as small as possible.

The ball screw does not rotate at a high speed and has a short running time at high speeds, so heat generation is not a major problem.

In recent years, bearing manufacturers at home and abroad have produced a special bearing for ball screws, which is a special radial thrust ball bearing that can withstand large axial forces, and general radial thrust. Shanghai Manlu is pretty good.
