Using Ultrasound Technology for Acoustic Bearing Lubrication Monitoring

March 14, 2017

Bearings produce less friction when they are properly lubricated. But how do we know? How can you be confident that friction forces are where they should be? How can you confidently apply just the right amount of grease to return friction levels to normal? How can you distinguish between a bearing that need grease and […]

Labeling Ultrasound Data Collection Points

December 13, 2016

To facilitate the initial learning curve, a labeling system was implemented to help technicians collecting data identify bearings that were part of the initial survey. These descriptors were laminated to prolong their life in the unfriendly environment of a typical cement plant. Standard locations for data collection needed to be understood since labels would become […]

Mistake #3 – Using a “Listen-Only” Ultrasound Instrument (Series 3 of 3)

September 20, 2016

Like any job there is a right way and a wrong way to do things. Simply listening to a bearing with an ultrasound device that gives no quantitative feedback is a recipe for disaster. The audible feedback is too subjective to draw any comparative conclusions. No two people hear the same and there is no […]

Mistake #2 – Over and Under Lubrication (Series 2 of 3)

September 13, 2016

The second mistake we should all avoid is adding too much, or not enough grease. Too much grease builds up pressure pushing the rolling elements through the fluid film and against the outer race. Increased friction and temperature dramatically shorten the bearing’s life. Not enough grease will have the same life-shortening effect. How do we […]

Mistake #1 – Lubricating based on TIME instead of CONDITION (Series 1 of 3)

September 6, 2016

Lubricating a bearing once per week or once a month may seem like a sensible thing to do. After all, performing scheduled maintenance at regular periods is an age old concept ingrained in each of us early on. Even OEMs still advise best practices based on time intervals to ensure maximum asset lifespan. The problem […]
