assessment of bearing condition by vibration analysis

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 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.
