We have a vertical motor driving the condensate pump. It is a 2000KW , 1490 RPM motor. The motor DE and NDE bearing vibration is going high. It is known that the outer race of DE bearing is rotating in the housing. 1X and harmonics say this. In addition, we have frequencies in 450HZ to 600HZ with a number of side bands. Bearing is NU 230. Appears to be bearing defect frequency but none of the peaks in this region is matching with bearing defect frequency or harmonic. The spectrum is attached herewith. Require help for giving a call for bearing replacement.
