Interview With an Expert Vibration Analyst: 4 Stages of Bearing Failure

[@H2O1167]

Great teaching. Thank you sir. But how do you know what stage of the spectrum if you are seeing it for the first time? What are the indicators we should be looking for to tell us what stage it is?

[@Stubbornnut]

You should watch the whole playlist of videos. Under a certain range look at displacement. Over a certain range look at acceleration. Check out my whole channel.

Thanks sir to shear this knowledge! following you from Iraq

[@Stubbornnut]

very happy to have you watching. i hope you gain something from the videos! all the best 😃

[@ZiaUllah7]

Very helpful

[@Stubbornnut]

thank you for the positive feedback and for watching my videos. i appreciate it.

[@JLPaper7]

Could you indicate how it translates to the machine of analysis? How is the difference between envolepe and acceleration in this case? What happens if you see it in velocity, is that stage 4?

[@Stubbornnut]

all early stages of bearing failure discussed here are using peak view to identify early faults. as the spike moves to lower frequency in stages 3 and 4 you will see it in velocity. you have to set your box to look for these during your route.

i have an entire video playlist that explains the acceleration and velocity vs amplitude and where you use them.
