Vibration in Bearings - Calculations for Bearing Defect Frequencies

Some bearing manufacturers now offer databases and computer programs to determine bearing frequencies. Another fact that assists in recognizing fundamental bearing frequencies is that they almost occur at non-integer multiples of operating speed (non-synchronous) such as 4.3 x rpm, 5.6 x rpm, 6.8 x rpm, etc.
