NSK tools for troubleshooting can help with identifying and rectifying issues such as:

  • Bearing Contamination
  • Bearing Misalignment
  • Moment Load Issues
  • Axial & Radial Load Issues
  • Insufficient Lubrication
  • Careless Handling

When a rolling bearing is damaged during machine operation, the entire machine or equipment can seize or malfunction. Since bearings that fail prematurely or unexpectedly cause trouble, it is important to be able to identify and predict failure beforehand, so that preventive measures can be adopted.

Poor lubrication, improper handling, selecting the wrong bearing, overdue roller bearing maintenance or incorrect analysis of the shaft and housing can be the cause.

Considering the operation of the bearing before the failure, investigating the lubrication conditions and the mounting condition and carefully observing the damaged bearing itself will help you determine the cause of bearing damages and countermeasures to prevent them happening again.
