A Lubrication Condition or a Mechanical Condition?

July 11, 2017

When monitoring your bearing lubrication with ultrasound, it is important to watch for very high values in your condition indicators (total RMS and Peak values). After applying grease, both values should decrease proportionately. This is a sign the bearing was under-lubricated. If the total RMS value lowers and the peak value stays relatively the same, then the bearing has a mechanical condition that is generating impacts.
