Bearings and gears are where condition monitoring earns its keep, because both give weeks or months of warning if you know how to listen. Bearing & Gear Analysis 101 teaches you to read that warning. You will learn the anatomy of a rolling-element bearing and the four defect frequencies it produces — BPFO, BPFI, BSF and FTF — how to calculate them from geometry and speed, and why a defect first shows up as tiny, repetitive impacts long before the overall level moves.
That is exactly where envelope demodulation shines, and this course shows how it lifts weak bearing impacts out of the noise floor when the raw spectrum still looks calm. You will use crest factor and kurtosis as early-warning flags, follow a defect through the four classic stages of bearing failure, and then turn to gearboxes — the gear-mesh frequency, the sidebands that reveal an eccentric or cracked tooth, and hunting-tooth patterns. Catch these early and you convert an unplanned breakdown into a scheduled repair, which is the entire point of the practice.
