Condition assessment of slow-speed bearings remains an area of difficulty for many vibration analysts. Over the last 10 years, the simplicity of using Ultrasound for this application has been recognised. This presentation reports on some measurements taken on bearings rotating at 3, 2.3 1.6rpm using Ultrasound. The results compare the use of standard Ultrasound with the significantly increased data provided by the new generation of oversampled Ultrasound data.
How to unlock more information by taking more data is explained by comparing the results from the two methods.
1. Ultrasound is great for slow-speed bearings
2. Oversampled data con reveal otherwise hidden defects
3. Ultrasound identifies early stage bearing defects
