Estimating the remaining life of a rolling element bearing with vibration, ultrasound, oil, and infrared analysis

Jason Tranter, Founder and CEO, Mobius Institute


Every vibration analyst must be able to detect rolling element bearing fault conditions. But the question everyone wants to be able to answer is; “when will the bearing fail?” In this animated presentation, Jason will explain how vibration analysis, ultrasound, oil analysis and wear particle analysis, as well as infrared analysis, can be used to detect rolling element bearing faults and provide an indication of the remaining life of the bearing. Using these condition monitoring techniques correctly, it is possible to detect a bearing fault a year or more before it would ultimately fail. But using these technologies, it is possible to look for signs that indicate the approximate remaining life. Case studies will also be presented that utilize these technologies.
