Vibration in Bearings - Calculations for Bearing Defect …

As the bearing deteriorates further, 1 x rpm sidebands develop, especially around the inner race frequencies. This is due to amplitude modulation as the defect (s) passes in and out of the "load zone." They can occur at +/- 1 x rpm, +/- cage frequency, or +/- ball spin frequency, depending on the situation.
