1. Correct bearing selection.
 
Satisfactory SKF bearing http://www.bearing-a.com/SKF/   service life begins with correct bearing selection.
From the beginning, the bearing designer extended the service life and equipment performance by selecting the correct bearing for different applications.
This process takes into account a number of factors, such as load, hardness, bearing life prediction, operating environment, and so on.
 
2. Correct storage.
 
In principle, all SKF bearings should be stored in their original packaging before installation.
They need to stay in a clean, moisture-free, relatively constant environment.
Rolling bearings should be kept away from dust, water and corrosive chemicals.
Shaking and shaking may permanently damage the mechanical properties of the bearings, so they must be avoided during processing and storage.
 
Basically, all SKF bearings must be stored horizontally, because some heavier bearings are placed vertically for long periods of time and may be distorted by their weight.
 
Precoated (or sealed) bearings need to be especially careful because the density of oil changes after a long period of storage.
In this way, when the bearing is first used, there will be a certain degree of rotational noise.
Therefore, the time of shelving of this kind of bearing should be controlled according to the principle of advanced first out.
 
3 clean
 
Cleaning is very important for rolling bearings.
The surface roughness of the rotating surface and rolling element of the SKF bearing ring is usually 1/10 of a m, so the smooth surface is very sensitive to the damage caused by the pollutants.
Rotating surface lubrication layer is usually between 0.2 ~ 1 mu m, is greater than the lubricant type size particles of impurities are influenced by the excessive rolling rolling element and partial pressure in the bearing steel, eventually lead to permanent material fatigue.
 
In addition to this, the dust particles in the external environment can be up to 10 mu m, which can also cause damage to the bearing.
Therefore, clean and clean environment is very important for bearing storage and installation.
 
4. Fully prepare and reinstall.
 
Bearings should be carefully installed and disassembled using appropriate tools.
Industry experts estimate that 16 percent of premature bearing failure is due to incorrect installation.
For a large number of installations (for example, in a production facility), it is usually necessary to strictly control the installation of the conditions and the proper bearing installation equipment.
 
However, in maintenance or replacement work, the environment is varied.
Therefore, in order to ensure the longest bearing life, comprehensive preparation is necessary for bearing installation.
 
First of all, relevant documents, such as drawings, maintenance manuals, product specifications, etc. need to be carefully studied.
Next, all bearing elements, such as shaft, distance ring, cap, washer, etc. must be kept absolutely clean and free from contamination.
The status of adjacent components should also be examined carefully.
 
5. Carefully install and disassemble.
 
Select appropriate installation methods (mechanical or hydraulic) and tools according to different applications and bearing sizes and types.
Here are some basic principles of bearing installation:
 
1. Do not apply the installation force on the rolling element, which can easily lead to the local overload of the rolling element and the contact surface of the seat ring, leading to premature failure of the bearing.
 
2. Do not use any hard tools (such as hammer, screwdriver, etc.) directly on the surface of the bearing, which will cause the bearing ring to break or break.
 
3. Follow the guidance of the recommended supplier of installation equipment.
 
About 90 percent of rolling bearings have never been removed from their equipment, and usually only larger bearings are removed due to scheduled preventative maintenance procedures.
As with the installation of a bearing, the removal of the bearing must be carefully prepared. In the process of disassembly, ensure that the adjacent parts, such as the shaft and shaft, are not damaged.
Select appropriate methods and tools according to the type, size and application of the bearing.
 
Designers should note that well-designed bearing positions can greatly simplify the installation and disassembly of bearings, thereby reducing maintenance costs.
 
 
6 Proper and proper lubrication.
 
Lubricants can isolate metal bearing surfaces (such as rolling elements, bearing rings and bearing covers), thereby reducing friction, protecting metal parts, and preventing contamination and impurities.
Various kinds of lubricants (including fats, oils and solids) are available for different operation conditions.
The correct choice of lubricant is very important to prolong the service life of the bearing and equipment.
 
Due to the excessive rolling rolling parts, bearing lubricant subjected to mechanical stress for a long time, in addition, a long time especially in high temperature, wet or the pollution of the environment, the chemical property of the lubricant will change.
All this leads to a gradual decline in the quality of lubrication.
Therefore, to ensure the maximum service life, the bearing should be lubricated periodically.
The lubrication period depends on the operating conditions, such as temperature, speed, environment, etc.
Only in prelubricated or sealed bearings (also known as "life lubricated" bearings), bearing life depends on the life of the lubricant.
 
The lubricant must be kept in accordance with the manufacturer's instructions, in particular to keep the lubricant clean and free from contamination.
Before each use, carefully check the quality of the lubricants, and the use of old or contaminated lubricants may cause the bearing to fail prematurely.
 
7 Vii. Status detection/maintenance.
 
Generally speaking, rolling bearings are very reliable, although they have a limited life span.
Like all other important parts of the machine, they should be regularly checked and maintained.
The frequency of inspection and maintenance depends on the importance of individual applications and the operating conditions of each device.
 
Because of the key of bearing action, it is recommended to add state monitoring function at its design stage.
Important parameters of machine operation, such as vibration and noise, can be continuously monitored and precautionary measures are taken before the unforeseeable and costly equipment is shut down.
 
8  Training -- the foundation of good practice.
 
Practice makes perfect, but proper training is the foundation of practice.
Well-known bearing manufacturers offer a variety of training courses for business, technical or workshop staff.
If the technician has basic knowledge in the process of bearing the bearing, it is possible to avoid major errors.
Design and product development engineers can optimize the bearing design, maximize equipment performance, and minimize life cycle costs.
 
Bearings are usually important components in pumps and other equipment, and although the best quality bearings are reliable, be careful to ensure that they have the longest service life.
The right preservation, the erection and dismantling of cautious, sufficient lubrication and lubricant, the correct condition monitoring, timely maintenance, and finally improve the personnel training, to improve the service life of the bearing and equipment performance is very important.
