Using Ultrasound To Detect Bearing Failures

Damage inside of a rolling element bearing begins with sub-surface fatigue and results in a detectable sound signal that occurs in the ultrasonic frequency range. Ultrasound can be used to detect these Stage 1 bearing defects which would not be visible looking at typical vibration spectrum. If you listen to the sound that is being … Continue reading Using Ultrasound To Detect Bearing Failures
