Technology of prolonging the service life of IKO railway bearing

  • In order to make the service life of railway bearings longer, today I would like to share with you the technology of prolonging the service life of IKO bearings.Technology of prolonging the service life of IKO railway bearing

Technology of prolonging the service life of IKO railway bearing

  • 1. Installation of railway bearings
  • Whether the installation of railway bearings is correct or not affects the accuracy, service life and performance. Therefore, the design and assembly department should fully study the installation of IKO bearing. It is hoped that the installation will be carried out according to the operating standards. Items of operating standards are usually as follows:Technology of prolonging the service life of IKO railway bearing
  • (1) Clean the bearing and its related parts;
  • (2) Check the size and finish machining of related parts;Technology of prolonging the service life of IKO railway bearing(3) Installation;
  • (4) Inspection after installing the bearing;Technology of prolonging the service life of IKO railway bearing
  • (5) Supply lubricant.Technology of prolonging the service life of IKO railway bearing
  • 2. Alignment
  • After the IKO bearing is installed, if it is not carefully aligned, the alignment may cause the 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.
  • 3. Basic condition monitoring
  • During use, the basic external conditions of IKO bearing operation shall 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 of prolonging the service life of IKO railway bearing
  • 4. Re lubrication
  • In the process of operation, the railway 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 IKO 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.
  • 5. Remove
  • When the railway bearing will reach its final service life, it should be replaced. Although IKO bearings can no longer be used, correctly removing the original bearings and replacing new bearings in time can play a good role in prolonging the service life of new bearings. 
  • 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.

  • The so-called fracture refers to a small part of the fracture due to the impact or excessive load exerted by the cylindrical roller bearing on the retaining edge of the raceway wheel or the local part of the roller angle. The reason for this is that the fag bearing was hit during installation. Excessive load. Poor use such as falling.
  • Corresponding measures shall be taken to improve the installation method (hot installation and appropriate tool clamp). Correct load conditions. Fag bearing is installed in place to support the retaining edge.
  • State when fag bearing is jammed
  • The so-called jamming injury is the surface damage caused by the micro burn of the part of the cylindrical roller bearing caused by fag surface injury. Linear scars in the circumferential direction of slide surface and rolling surface. 
  • The cycloidal scar on the end face of the roller is close to the clamping wound on the shaft ring surface of the end face of the roller.
