Acoustic Lubrication Guidelines for Rolling Element Bearings in Electric Motors

The Reliability Conference - 41:03  
by Jim Hall, The Ultrasound Institute

Acoustic lubrication is the method of using a bearing’s ultrasound signal to determine if a bearing requires lubrication or if the lubrication is sufficient. An under lubricated bearing will generate a greater signal than a properly lubricated bearing. This presentation presents the new Acoustic Lubrication Guidelines for Rolling Element Bearings in Electric Motors developed by the Association of Asset Management Professionals.
