Roller bearing

Bearing damage is the most common cause of machine disruptions or failures

Bearing damage is the most common cause of machine disruptions or failures. Although
they have a robust and compact design, these components are subject to diverse
influences that affect their service life:

  • High bearing loads
  • Assembly errors
  • Lubrication problems
  • Contamination from outside
  • High operating temperatures
  • Intrusion of water.


To prevent and avoid bearing damage, active condition-based maintenance measures have
proven effective, such as:

  • Monitoring of the damage frequency for inner race, outer race, rolling element and cage
  • Analysis of the envelope spectrum for identification of damaged components
  • Monitoring of bearing vibration by means of overall readings (shock pulse)
  • Monitoring of bearing temperature
  • Alignment of bearing supported shafts
  • Field balancing of bearing supported rotors to reduce reaction forces.
