Is it worth trying to get the bearing defect frequencies on slow rolling dodge bearings. Under 300 rpm. The sppeds vary depending on the production of the plant.. I am taking spike energy readingds to monitor the bearings. So as of know it is a trending thing until i see amplitudes change . Advise?

Yes, definitely.

And include running speed as precise as you can get it. At low speeds, you can't count on there being a good 1 x running speed signal to show you the speed.

As Danny said "YES" absolutely.
