Maintenance scheduled a replacement during a planned weekend shutdown. Upon dismantling the bearing, engineers found a 2-millimeter pit on the outer raceway. Replacing the bearing cost $450 in parts and prevented an unplanned production halt valued at $80,000.

For non-stationary signals where frequency content changes over time, time-frequency analysis methods such as spectrograms and wavelet transforms provide a more complete picture. Studies on rolling bearings have shown that spectrograms can visually depict signal strength over time at different frequencies, offering insights that pure time or frequency analysis may miss.

The team removed the fan housing cover. They discovered that the fan blades had uneven cement dust caked on three of six blades. Cleaning the blades and performing a two-plane balance reduced the 1x peak by 90%.

Link the vibration spectra to physical evidence found during repairs (e.g., photos of broken bearings).

Vibration analysis is a widely used technique for monitoring and diagnosing the health of rotating machinery, such as pumps, motors, and gearboxes. By analyzing the vibrations of a machine, maintenance personnel can identify potential problems before they lead to equipment failure, reducing downtime and increasing overall efficiency. In this paper, we will present several practical case studies on vibration analysis, highlighting its application in real-world scenarios.
