hello everybody
im a new member here im a vibration analyst, i want to ask about something related to the air blower vibration, dose anyone have the vibration severity standard for it and also when i get a captured data for the blower axis i see a high vibration RMS a high impacts and the look of damaged bearing on the spectrum
but its not, its a new bearing how this comes if anyone have an idea reply me, and i will thankful

Can you post the data? Just because it is a brand new bearing does not mean that it is OK. You can get bad bearings from the manufacturer. There can also be installation and clearance issues at play here.

Hi Ahmed.mustafa,

About your question, I not sure what type of RMS is high.
Whether velocity, acceleration or displacement is high.
Since RMS is high, please check your alignment and the balancing first.
Please specified the working blower RPM and type .
