Technology for prolonging the service life of IKO flange bearing

Bearing installation

  • Whether the IKO bearing is installed correctly affects the accuracy, service life and performance. Therefore, the design and assembly department should fully study the installation of flange bearing. 
  • It is hoped that the installation will be carried out according to the operating standards. Items of operating standards are usually as follows:

  • (3) Installation;
  • (4) Inspection after installing the bearing;Technology for prolonging the service life of IKO flange bearing
  • (5) Supply lubricant.Technology for prolonging the service life of IKO flange bearing
  • 2. Alignment
  • If IKO is not carefully aligned after the bearing is installed, the alignment may cause the flange bearing to suffer additional load, friction and vibration. These may accelerate fatigue and reduce the service life of bearings, and may 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.Technology for prolonging the service life of IKO flange bearing
  • 3. Basic condition monitoring
  • During use, the basic external conditions of flange bearing operation should be monitored frequently, such as temperature, vibration and noise measurement. These regular inspections will identify potential problems as soon as possible, prevent unexpected machine stoppage, realize the production plan and improve the productivity and efficiency of the plant.Technology for prolonging the service life of IKO flange bearing
  • 4. Re lubrication
  • In the process of operation, IKO bearing requires correct re lubrication to perfect its performance. The methods of bearing lubrication are divided into grease lubrication and oil lubrication. In order to make the flange bearing function well, first of all, choose the lubrication method suitable for use conditions and purposes. 
  • If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing.Technology for prolonging the service life of IKO flange bearing
  • 5. Remove
  • IKO bearing should be replaced when it will reach its final service life. 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 prolonging the service life of the new flange bearing.
  •  First, the proper unloading method and the use of tools will help prevent damage to other machine components. Second, incorrect unloading technology may cause harm to the operator.Technology for prolonging the service life of IKO flange bearing

Technology for prolonging the service life of IKO flange bearing

  • In the process of operation, IKO bearing requires correct re lubrication to perfect its performance. The methods of bearing lubrication are divided into grease lubrication and oil lubrication. 
  • In order to give full play to the function of the bearing, it is necessary to select suitable service conditions and use correct lubrication methods. If only lubrication is considered, the lubricity of oil lubrication is dominant, but grease lubrication has the advantage of simplifying the structure around the bearing. Therefore, the selection should be based on the needs of the actual use environment.
  • 4. Be careful when unloading the bearing
  • When the needle roller bearing will reach its final service life, it should be replaced. Although the needle roller bearing can no longer be used, correctly removing the original bearing and replacing the new bearing in time can play a good role in prolonging the service life of the new bearing.
  • (1) Proper removal methods and the use of tools will help prevent damage to other machine components,
  • (2) Improperly removed technology can be hazardous to the operator.Technology for prolonging the service life of IKO flange bearing
  • If the needle roller bearing is well lubricated and correctly blocks sundries and moisture, it means that the oil seal should not be worn However, when opening the bearing housing, check the bearing and regularly check the oil seal Check the condition of oil seals close to IKO bearing to ensure that they are sufficient to prevent hot liquid or corrosive liquid or gas from penetrating into the bearing along the axis. If the oil seal is worn, replace it as soon as possible
  • High temperature often indicates that the bearing is in abnormal condition High temperatures are also harmful to lubricants in bearings Sometimes bearing overheating can be attributed to the lubricant of the bearing If the bearing operates for a long time at a temperature of more than 125 ℃, the service life of the bearing will be reduced
  • The causes of high-temperature bearing include insufficient or excessive lubrication, magazine contained in lubricant, excessive load, bearing damage, insufficient clearance, high-temperature friction caused by oil seal, etc
  • The bearing IKO body and the inner and outer race raceways are subjected to periodic fluctuating loads, resulting in periodic contact stress. When the number of stress cycles reaches a certain value, fatigue spalling occurs on the working surface of IKO body or inner and outer race raceways.
  •  If the load of the bearing is too large, it will aggravate this fatigue. In addition, improper bearing installation and shaft bending will also produce raceway spalling. The fatigue spalling of bearing raceway will reduce the operation accuracy of shaft and cause vibration and noise of mechanism.
  • There is a return fire color on the raceway and IKO body of the burned bearing. The causes of burns are generally insufficient lubrication, unqualified or deteriorated lubricating oil quality, and too tight bearing assembly.
  • Uneven pits appear on the contact surface between the raceway and the roller of the bearing, indicating that the needle roller bearing produces plastic deformation. 
  • The reason is that under the action of large static load or impact load, the local stress on the working surface of IKO bearing exceeds the yield limit of the material, which usually occurs on the bearing rotating at low speed.
