Nice catch.
In addition, I suggest use of Ultrasound technology for bearing inspection. This will identify the problem in an early stage, resulting in early maintenance/repair, and will avoid problem to reach this state.
indeed. will do the same.
You got the bearing fault but did you the proper ISO fault level? It looks like it was called early. ISO usually indicates that 0.25in/sec or 6mm/sec. I use the time between discovery and confirmation to call to let maintenance know there is a fault so they can order parts and get prepared and then coordinate with operations for an optimal shutdown window.
Dear Ty Huffman,
Running RPM is 496 only and if we wait till 6 mm/sec level then it’s too late for such speed. even at this vibration and impact level bearing also get 70-degree temperature and usually temperature range is 50-55 degree.
