Bearing maintenance
 
In order to maintain the original performance of a bearing for as long as possible, proper maintenance and inspection should be performed. If proper procedures are used, many bearing problems can be avoided and the reliability, productivity, and operating costs of the equipment containing the bearings are all improved. It is suggested that periodic maintenance be done following the procedure specified. This periodic maintenance encompasses the supervision of operating conditions, the supply or replacement of lubricants, and regular periodic inspection. Items that should be regularly checked during operation include bearing noise, vibration, temperature, and lubrication.

If an irregularity is found during operation, the cause should be determined and the proper corrective actions should be taken after referring to manufactures specifications.

If necessary, the bearing should be dismounted and examined in detail. As for the procedure for dismounting and inspection, refer to manufactures specifications for the Inspection of Bearings.

The main causes for bearing failure is:

  • Poor Lubrication 36%
  • Fatigue 34%
  • Improper mounting 16%
  • Contamination 14%
