It is interesting to see how the following bearings 6309 2Z/C3 and 6209 2Z/C3 from a motor driving a pump, presented a critical increase in vibration in acceleration of the envelope filter after maintenance. Frequencies of damage with sidebands were observed at the speed of operation. The result is bearings with markings on the raceways that show axial overload and the rolling elements have circular markings in different areas.
