Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings

The service life of SKF Bearing is closely related to manufacturing, assembly and use. It must be done well in every link. Only by paying attention to the above precautions when using non-standard bearings, can the bearing be in the running state, so as to prolong the service life of the bearing.

  • In order to ensure that the bearing always operates in good condition, regular maintenance and repair is necessary, so as to prevent accidents and prevent accidents, improve the production efficiency of the enterprise and save costs. To be engaged in the professional maintenance of SKF bearings here, there must be a standard and systematic operation process, including the detection of operation status, lubricant, regular disassembly, noise, temperature and so on.
  • After the bearing is pressed into the bearing, it shall rotate flexibly without blocking feeling. If there is obvious inflexible rotation, it indicates that the size of the shaft is too large and the tolerance should be reduced. Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings
  • If there is an obvious “rusty” feeling when the bearing is rotated by hand after being put into the bearing, it may be that the tolerance of the bearing is too large or the roundness of the bearing is not good. Therefore, when controlling the tolerance of shaft and bearing, we should also control the roundness.Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings
  • whether the bearing is installed correctly is directly related to the accuracy, service life and performance of the bearing. Therefore, the installation and design department shall fully study the installation of the bearing and analyze the structure of the bearing in order to ensure the normal operation of the bearing:Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings
Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings
  1. First,clean the bearing and its related parts:This is very important. Be sure to clean it to prevent sundries. Check the size and finish machining of related parts; This requires some special tools to ensure the installation accuracy of the bearing. Inspection after installing the bearing; Check whether SKF bearings are matched and whether there are errors. The supply of lubricant requires careful operation, which is very important.Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings
  2. Second, basic monitoring conditions of bearing:Some professionals are required to inspect the bearings regularly, so as to find potential problems early, prevent unexpected machine suspension, enable production and improve the productivity and efficiency of the factory. During the use of bearings, the basic external conditions of bearing operation should be monitored frequently, such as temperature, vibration and noise measurement, so as to prevent accidents.Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings.
  3. Third, bearing alignment and alignment:These operations may accelerate fatigue and reduce the service life of bearings and damage the service life of other machine parts. In addition, increased vibration and friction may greatly increase energy consumption and the risk of premature failure. 

However, if the alignment is not carefully carried out after the bearing is installed, the alignment may cause the SKF Bearing to suffer additional load, friction and vibration. As a result, the bearing is damaged prematurely, so it should be aligned and straightened!Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings

  • Fourth, re lubrication of bearing:If the bearing considers lubrication, the lubricity of oil lubrication is dominant. However, grease lubrication can simplify the specialty of the structure around the bearing. In the process of operation, the bearing requires correct re lubrication, which can make the bearing operate healthily. Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings.
  • In order to make the bearing function well, first of all, choose the lubrication method suitable for the use conditions and purpose. Whether it is oil lubrication or grease lubrication depends on the specific situation of the bearing!Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings
  • Fifth, bearing removal:Use proper tools for removal, which will help prevent damage to other machine components. Incorrect removal technology may cause damage to the bearing. If SK bearing reaches its final service life, it should be replaced. Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings.
  • Although the bearing can no longer be used, correctly removing the original bearing and replacing the new bearing in time can play a good role in promoting the extension of the service life of the new bearing. Therefore, the replacement of the old and the new is very important, which requires professional personnel to check and operate.
  • When the bearing is installed on the rotor for dynamic balance, it is easy to put the iron filings generated during dynamic balance into the non-standard bearing, so the dynamic balance is carried out before installing SKF Bearing. In order to facilitate assembly, some manufacturers apply some oil or grease in the bearing chamber for lubrication effect during assembly, but it is often difficult for operators to control the amount. Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings.
  • If more oil or grease is accumulated in the bearing chamber, it is easy to enter the bearing along the shaft when the bearing rotates. The bearing shall not be coated with oil or grease. If it must be coated, it shall be controlled and there shall be no accumulation in the bearing chamber.
  • Use the bearing in a standardized way until the end of the bearing life. Such cases are relatively rare. Generally, SKF bearings are damaged due to various reasons in the process of operation and production, and the bearings are directly scrapped in serious cases. Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings.These reasons are nothing more than installation, use and lubrication.
  • The common ones are caused by the jamming of the ring stop edge of non-standard bearings. The main reason is insufficient lubrication or foreign matters.Several knowledge elements need to be paid attention to in the correct installation of SKF non-standard bearings.

In view of these problems, we should first eliminate the causes of the accident, and investigate the recurrence of similar accidents on one side in combination with the use environment, location, structure and other aspects, which will bring unnecessary trouble.
