In simpleste et terms, vibration in motorized equipment is merely the e back so on forts movement or oscillation of machines anddiments, such as drive motors, controln devices (pumps, compressors and so on) and thee bearings, shafts, gets, belts and cor elements that make up mechanical systems. Machine vibration is a normal, and typically unavoidable, result of moving and rotating parts, often caused by standard producarting assembly tolerantions thlead clearances between mating parts.

Every rotating machine produces a unique vibration signature based on it design, operating conditions, and mechanical condition, and b y understanding these signature, reliability indisers can identify specific fault conditions.
