Journal Bearing Analysis Techniques
Gulf Coast Training Center
In this course students will learn the basic principles of journal bearing design and rotor dynamics in order to apply analysis techniques using time waveform, FFT spectra, orbits, shaft centerline plots, and load path plots. Accelerometer and proximity probe vibration data as well as dynamic strain data are covered.
Actual case studies are reviewed to demonstrate each of the discussed principles.
- Understand bearing design theory and how it applies to troubleshooting
- Understand basic rotor dynamic theory and how it applies to troubleshooting
- Know how to collect the data necessary to plot a proper orbit
- Understand the value of filtered and unfiltered orbits
Continuing Education Credit Hours: 16 Hours
Journal Bearing Analysis Class Reviews :
"Several of our engineers attended the online Journal Bearings Analysis course offered by Pioneer Engineering during May of 2020, and found it to be well organized and thorough, covering some aspects of journal bearing design and difference, and analysis methods. Mitch provided a good bit of history and a high level but thorough overview of journal bearing design and design features, and then spent the bulk of the course discussing how those specific features interact with operating conditions to determine bearing performance. The comparative analysis of using accelerometers vs. prox probes vs. the new FDS strain sensors for bearing monitoring and analysis was extremely useful, as it highlighted some limitations of each, and things to watch out for. This whole course will help us be more holistic in our approach to vibration monitoring and analysis on journal bearing machines, and give us additional things to consider when we evaluate apparent issues and determine a path forward. The course was well worth the investment."

“I wanted to let you know that the Journal bearing class that I attended on June 9th and 10th was on of the very best classes that I have ever attended. It was a real world class with a journal bearing rotor kit that allowed for real time comparisons of each type of sensor under different operating conditions. What makes this class so effective is not just the in class study of theory on why journal bearing react the way they do but the ability to go out to the shop and observe on the rotor kit what was covered in class. This I believe is the missing link in a lot of training. For a field person such as myself to see first hand how each type of sensor is used and how that information is displayed in real time is invaluable. I would highly recommend anyone who works in the field with journal bearing to attend this class and gain the first- hand knowledge of the theories and principles of journal bearings in action. Mitch has the unique ability to make a very complex subject understandable and his wealth of knowledge and experience is I believe second to none. In closing awesome class for anyone working with journal bearings and rotor dynamics.

“I appreciate the enthusiasm and wealth of knowledge that Mitch delivered in the short, two-day class. I have attended many training sessions from multiple providers, I have a Category 3 certification from the Vibration Institute, and a Category 4 certification from Technical Associates and I have been through several classes at Emerson Process Management’s training facility. In short, I have been fortunate enough to sit in front of some of the most brilliant minds in the vibration industry.
I can honestly say that I enjoyed listening to Mitch speak to our small class more than any I have attended in my 16 years as an aspiring vibration analyst. Being intelligent and being able to convey that knowledge to a classroom full of people is two totally different things. Mitch does just that, and probably better than anyone I have ever had the pleasure of sitting in front of.”

"There are not many that offer the professional education qualities and practical real world experience. You are among the Vibration elite like Jim Berry, PE, Ron Eshleman, Ralph Buscarello, Robert C. Eisenmann, Art Crawford and Charles Jackson. (Only the bolded names are still with us.)
Thank you for all you do to advance industry – and congratulations on the new technology to replace prox probes – I know you will be amazingly successful and the market will respond.”

"I enjoyed seeing the mathematical relationships laid out in the course the most. Seeing the design equations gives me a clear understanding of what’s happening physically and these were covered in excellent detail. I can better understand bearing issues we have when we bring vibes people on site. Before I just sort of nodded along because I didn’t know what they were talking about, but now I’ll be able to get it and even help contribute to the troubleshooting. I enjoyed learning all of the material and Mitch was a great teacher. I think a great target audience for this course would be rotating equipment engineers in manufacturing industries. Another subset of folks who may find it interesting would be process engineers; it’s never a bad idea to familiarize yourself with your equipment a bit more instead of always just considering what’s going on 'in the pipes'”.
