An Overview of Bearing Vibration Analysis t c Dr. S. J. Lacey a Engineering Manager, Schaeffler (UK) Ltd r t Rolling element bearings are often s b Vibration produced by rolling bearings can used in noise sensitive applications, e.g. A household appliance electric motors which be complex and can result from geometrical often use small to medium size bearings. imperfections during the manufacturing Bearing vibration is therefore becoming increasingly important from both an process, defects on the rolling surfaces or environmental consideration and because it geometrical errors in associated components. is synonymous with quality. It is now generally accepted that quiet Noise and vibration is becoming more critical running is synonymous with the form in all types of equipment since it is often perceived to be synonymous and finish of the rolling contact surfaces. As a result, bearing manufacturers have with quality and often used for predictive maintenance. In t
