Premature roller bearing failure Learning to troubleshoot bearing problems is a crucial part of any maintenance program. As many as 13% of industrial motor failures happen because of bearing failures. Moreover, 60% of equipment breakdowns involve bearing wear. Most defects result from a combination of failure modes, and each failure is usually due to a mixture of causes. Vibration: A chief precursor to bearing failure Usually, before bearings fail, the problem appears in the form of vibration. For example, roller bearings will cause vibration each time they pass over a damaged or pitted roller bearing race. Without being harmful or invasive, vibration analysis provides the most detail about what is happening inside machinery by detecting minuscule changes in acceleration, direction or velocity that may indicate bearing wear, installation error or other mechanical problems. Wireless condition monitoring vibration sensors installed on a bearing housing can provide maintenance teams wi
