Low amplitude sidebands in the high frequency data at 3.09 orders, which is very close to the outer race bearing defect frequency in the motor bearings. • The waveform data was also showing just over 14 G’s peak to peak.
A closer look at the acceleration spectrum shows the sidebands of outer race defect frequency clearly.The I-DNA measurement (High frequency vibration analysis technique) also shows the harmonics of 3.09 orders confirming the existence of an outer race bearing defect. • Based on our findings our recommendation was to replace the motor and laser align the machine. • Ensure the coupling and all of its components are in good condition. • Ensure that all machine bolts are t
orqued properly.
