mixer motor

[Jed057]

Dear guru;
There is a mixer motor 75 kw runing with VSD.
But having some high vibration at 40-50 hz.
We are suspecting that may be bearing problem.
Currently,this is single taper bearing but client advise to change to both taper bearing in x shape??
Please advise whether we need for both taper bearing ornot?
Normally ;How many bearing we required for mixtor motor at shaft.
Thanks

Another possibility - the first critical speed of the agitator system occurs at 40-50 Hz. Check that out with your mixer vendor. They can help.

Good luck,
