In this video, Jason Tranter first discusses the most common reasons why rolling element bearings fail, including lubrication problems, lubricant contamination, excessive loading, and installation and handling. Next, the video summarizes how a variety of condition monitoring technologies can be utilized to determine the condition of rolling element bearings, including basic and advanced vibration analysis, oil analysis, wear particle analysis, and thermography. And finally, and most importantly, Jason discusses how to make changes in order to extend the life of rolling element bearings through precision maintenance techniques. Some of the techniques summarized include precision balancing, precision alignment, resonance elimination, improved installation techniques, improved lubrication practices and others.
The aim of the video is to highlight the fact that it is not enough to simply use vibration analysis and other condition monitoring techniques to detect when a bearing may fail; it is essential to understand the causes and failure modes of rolling element bearings, and to do everything possible to reduce the likelihood of rolling element bearing failure.
