Roller bearing faults kit (PT 500.12)

Roller bearing faults kit (PT 500.12)

assessment of bearing condition by vibration analysis



  • Vibration analysis is a key tool in estimating the condition of a roller bearing.
  • The slow change in the vibration spectrum provides indications of the remaining life of a bearing and can be used as a criterion for its replacement.
  • The spectral distribution can deliver accurate information on the type and location of the damage.
  • This accessory setup contains six roller bearings on which different faults can be detected and explained.
  • The radial load on the bearing can be set within broad limits using the belt drive accessory set PT 500.14(setting of belt tension; fixed load).
  • The accessory setup is mounted on the base plate of the machinery diagnostic base system PT 500.
  • To measure and evaluate the experiment, the computerised vibration analyser PT 500.04is required.
  • It includes all the necessary sensors, a measuring amplifier and analysis software to record the vibration phenomena.
