very good talk , great resume , love it

Glad you enjoyed it!

Hi ! Thanks for the informative video. 16:38 what might be the reason for the difference in the pattern of relative amplitude of harmonic family of inner race and outer race?

[@Stubbornnut]

outer race fault: energy dissipates through the bearing housing leading to attenuation at higher frequencies
inner race fault: energy is more efficiently transmitted and potentially amplified through the rotating components leading to increase harmonic amplitudes at higher frequencies.

[@rashwan2527]

Thanks a lot for clearing the concept :)

Thanks for gold bliar

[@Stubbornnut]

you’re welcome

Do you have slow info on bearing under 300rpm. I get rpm and number of balls. But i cant pass Charlottes test for cat2

[@Stubbornnut]

Under 600rpm use displacement.
