Introduction of bearing high temperature resistance(2022年10月09日)

FVrollingbearing — 2022-10-09T15:49:14+0900

https://www.fv-bearing.com/bearings-for-continuous-casters.html
A common question for bearings is whether the bearing can be used as a high-temperature bearing? If so, how much high temperature can different bearings withstand? In response to this problem, only to ensure that the bearing material can not only withstand high temperature, but also the bearing itself must have good Only mechanical properties can be regarded as a suitable high temperature bearing. Let's take a look at the high temperature resistance of the bearing.

1. High temperature resistance of bearings
Bearings of different materials, in terms of individual materials, what is the high temperature resistance? Here, we are talking about the mechanical properties that the bearing itself should have, and the core is about the speed, load and motion stability that the bearing needs to withstand during operation.

Bearings are an important part of modern machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its accuracy. To address the mechanical properties of bearings in high temperature environments, we need to know the percentage of carbon in the material.

Bearings of any material cannot be used as high-temperature bearings, and if the temperature exceeds 120 degrees, please choose the right high-temperature bearing manufacturer and the correct high-temperature bearing, because the purchase safety may affect your business, machinery and related personnel caused huge damage.

How to lubricate high-precision bearings in special use environments(2022年08月19日)

FVrollingbearing — 2022-08-19T15:13:45+0900

https://www.fv-bearing.com/products.html
We all know that for rolling bearings, bearing lubrication is very important, especially for high-precision bearings. In a general working environment, it is very simple to lubricate high-precision bearings, just inject an appropriate amount of lubricating oil or grease into it. However, for some bearings that work in special environments, simple lubrication methods are obviously not applicable, but the bearings cannot be lubricated because of this, otherwise the use effect will be affected. Today, Luoyang FV will teach you to solve this problem.

For bearings that work in special environments, you must first know where the environment is special, and then select the appropriate lubricating oil or grease according to the working environment to solve the bearing lubrication. The so-called special environment mainly includes these kinds, namely: high temperature, underwater, extremely low temperature, ultra-high vacuum, over-electric state and other different environments.

Precision bearings used at high temperatures are also special, because lubricating oil must have good high temperature resistance to avoid being affected by high temperature and affecting the performance of lubricating oil. If the bearing is running in ultra-high vacuum, it needs to be lubricated with a lubricant with very little evaporation, so as to avoid its rapid evaporation and unable to play a lubricating role. When the bearing is in an over-electric state, the phenomenon of discharge due to friction is easy to occur, so lubrication should also prevent the generation of arc sparks.

In most cases, the user can solve the lubrication problem very well. If your bearing operates in a special environment, it is best to consider the particularity of the environment and choose suitable lubricating oil or grease. If you do not know how to choose , you can contact us Luoyang FV bearing, our engineers are waiting for you at any time.

Four-row Cylindrical Roller Bearing Model for High Speed Wire Rod Mill Production Line(2022年08月18日)

FVrollingbearing — 2022-08-18T17:03:01+0900

In the metallurgical industry, rolling mill bearings are used in every link of the entire production line of a rolling mill. Different types of bearings need to be used in different positions, because different positions need to carry different loads and functions. Among them, the consumption of high-speed wire rod mills for roll neck bearings is very large. It is necessary to inspect rolling mill bearings on time and to replace and repair them, which can minimize the loss caused by downtime. However, sometimes replacing the entire set of rolling mill bearings is not a small expense for the customer. Sometimes only the inner component or outer ring of the bearing can be replaced, which saves costs for customers. Luoyang FV has sorted out the four-row cylindrical roller bearing models and related accessories of some commonly used high-speed wire rod mills.

The Basic Dimension of Common Four-row Cylindrical Roller Bearing Model(2022年08月16日)

FVrollingbearing — 2022-08-16T15:48:32+0900

https://www.fv-bearing.com/cylindrical-roller-bearings/Four-row-cylindrical-roller-bearings.html

Four cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Their friction is low compared with other roller bearings. As they are normally mounted with an interference fit on the roll neck, they are particularly suitable for rolling mill applications where the rolling speed is high.

The low bearing cross section allows for relatively large roll neck diameters in comparison with the roll diameter. Since very many rollers can be incorporated,the radial load carrying capacity is extremely high.

Four-row cylindrical roller bearings are only able to accommodate radial loads. They are therefore mounted together with deep groove or angular contact ball bearings, or with taper roller bearings, either radial or thrust designs,which take up the axial loads.

The four cylindrical roller bearings are of separable design, i.e. the ring or rings with integral flanges and the roller and cage assemblies can be mounted independently of the free rings, or all bearing components can be mounted separately. This considerably simplifies bearing mounting, maintenance and inspection. A certain limited axial displacement of the shaft with respect to the housing can be accommodated within the bearing.

Detection Method for Different Sounds from Rolling Bearings(2022年08月12日)

During the operation of the rolling bearing, sometimes the bearing will make some noise. Users will wonder, is there something wrong with my bearing, is the bearing broken? Today we will analyze the reasons for the sound of the bearing.

When the sound of the rolling bearing occurs, first observe the ball bearing or roller bearing and use the hearing to identify the irregular running sound. Or use a sound meter to check the size and sound quality of the rolling sound of the running bearing. Because the bearing is slightly damaged, abnormal sounds and irregular sounds can also be made, and these sounds can be distinguished with a sound meter.

If the rolling mill bearing is in a good continuous rotation state, the sound is also normal. Sharp hissing, squeaking and other irregular sounds often indicate that the roll bearing is in poor continuous rotation. A sharp creaking sound may be caused by improper lubrication. Improper bearing clearance can also cause metallic noise. Indentations in the bearing outer race track can cause vibration and cause a crisp sound. If it is caused by knocking scars during installation, noise will also be generated, and the noise will vary with the speed of the bearing speed. Intermittent noise may indicate damage to the rolling elements. Contamination in the rolling bearing can cause a hissing sound when the damaged surface is rolled over. Severe bearing damage can produce irregular and loud noises. Bearing damage can be detected by hearing, but usually the bearing must be replaced at this time. Using a sound meter can predict rolling bearing condition more accurately than listening to the sound with the ear.

FV Teach you to Choose Suitable Rolling Bearing Clearance(2022年08月11日)

When it comes to bearing installation, we will inevitably talk about a proper term: clearance. What is clearance? What is the important role of clearance on rolling bearings? How do we choose the appropriate clearance? Today FV bearings teach you some basic knowledge of clearance.

The so-called clearance is: the radial (axial) clearance of the bearing is the diameter of one ferrule relative to the other ferrule moving from the radial (axial) limit position to the opposite limit position when the bearing has no external load. Axial (axial) distance. In reality, due to the shape error of the ferrule and the inconsistency of the rolling elements, it should use the average value of the radial (axial) displacement in different directions of the ferrule and different relative positions of the ferrule and the rolling element.

The role of clearance: Clearance is an important technical parameter of the bearing. Its size and suitability directly affect the bearing installation and the load distribution, vibration, noise, friction, temperature rise, service life and bearing performance of the bearing. Technical performance such as running accuracy.

If the clearance is too large, the bearing area inside the bearing will be reduced, the stress of the contact surface will increase, and the service life will be shortened. Excessive clearance will also reduce the running accuracy of the bearing and increase vibration and noise. If the clearance is too small, there may be negative clearance (interference) in actual operation, which will lead to increased friction and heat generation and increased temperature rise, which in turn will make the effective clearance smaller or the interference larger. Such a vicious cycle will lead to bearing holding die. Whether the clearance is too large or too small, it is not good for the use of the bearing, so we have to choose the appropriate clearance.

Pay Attention to Radial Clearance when Installing and Removing Rolling Bearings(2022年08月08日)

There are many precautions when installing rolling bearings. For example, do not directly hammer the bearing end face and non-stressed surface. Professional installation tools should be used to make the bearing evenly stressed. If the mounting surface is lubricated, the installation will be smoother. If the interference is large, the bearing should be heated to 90~100℃ in mineral oil and installed immediately. When the disassembly is difficult, you can use the disassembly tool to pull out while carefully pouring hot oil on the inner ring. The heat will expand the inner ring of the bearing, making it easier to fall off. These are common sense when installing rolling bearings. What we want to talk about today is to pay attention to the radial clearance of the bearing when installing the bearing. Have you paid attention to the bearing clearance during installation?

First, a question: Is the smaller the radial clearance of the bearing the better? the answer is negative.

Not all bearings require the minimum working clearance, and the appropriate clearance should be selected according to the conditions. In the national standard 4604-93, the radial clearance of rolling bearings is divided into five groups - 2 groups, 0 groups, 3 groups, 4 groups, and 5 groups. The clearance values are from small to large, and group 0 is the standard clearance. The basic radial clearance group is suitable for general operating conditions, normal temperature and commonly used interference fit; bearings working under special conditions such as high temperature, high speed, low noise and low friction should choose a large radial clearance; Small radial clearance should be selected for precision spindles, machine tool spindle bearings, etc.; a small amount of working clearance can be maintained for roller bearings. In addition, there is no clearance for separate bearings; finally, the working clearance after the bearing is installed is smaller than the original clearance before installation, because the bearing has to bear a certain load to rotate, and the bearing fit and load are generated. amount of elastic deformation.

Therefore, the radial clearance of the bearing is not as small as possible. It should be selected according to the specific use situation. If you still can't choose, you can consult us. We are a professional rolling bearing manufacturer. We will provide you with Professional answer.

How to choose four-row cylindrical roller bearing according to its characteristics and structure?(2022年08月01日)

FVrollingbearing — 2022-08-01T15:58:29+0900

https://www.fv-bearing.com/cylindrical-roller-bearings/Four-row-cylindrical-roller-bearings.html
In the metallurgical industry, rolling mill bearings are essential and important components. Rolling mill bearings mainly include: four-row cylindrical roller bearings, four-row tapered roller bearings, double-row tapered roller bearings, spherical roller bearings, deep groove ball bearings, etc. Today we mainly discuss the four-row cylindrical roller bearing, which is widely used in the metallurgical industry.

First of all, let's understand the characteristics and structure of four-row cylindrical roller bearings:

The main features of four-row cylindrical roller bearings:
The bearing has a large rated dynamic load value in a limited installation space, and can be used for high-speed and high-precision rolling; at the same time, the bearing allows a relatively precise limit tolerance; the inner ring can be combined with the outer components (outer ring, complete set roller) interchangeable assembly, which is conducive to quick roll change.

Structure of four-row cylindrical roller bearings: There are several structures, but the most common are the following three:
FC type: two outer rings with ribs, integral inner ring and comb cage; FCD type: two outer rings with ribs, two inner rings and comb cage; FCDP type: two without outer ring. The outer ring of the rib, two inner rings, two outer retaining rings, one middle retaining ring, hollow rollers, and pin-type cage.

Knowing the structure and characteristics of the bearing will help us to choose a four-row cylindrical roller bearing. If you still have questions about the selection of rolling mill bearings, please consult us FV bearing, a professional rolling mill bearing supplier in China.
