PT 500.12 Roller Bearing Faults Kit Show data sheet (pdf file) Print page
PT 500.12 - A product from the GUNT 2E range
Technical Description

  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 set-up 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 set-up is mounted on the base plate of the machinery diagnosis base system PT 500.
  To measure and evaluate the experiment, the computerised vibration analyser PT 500.04 is required. It includes all the necessary sensors, a measurement amplifier and analysis software to record the vibration phenomena.


Learning Objectives / Experiments

- Vibrational spectrum of the running noise of roller

- Influence of damage to outer race, inner race or

  roller body, on the spectrum
- Estimating service lives of roller bearings
- Influence of the lubricant on the vibration spectrum
- Detection of faulty roller bearings
- Understanding and interpreting frequency spectra
- Use of a computerised vibration analyser


* Assessment of bearing condition by vibration

* Comparison of bearings with different faults
