Gear Box Calculator - Bearing Calculator Module

This is a screen shot of the Sideband Calculator.

Bearing frequencies calculated are:

• BPFI - Ball Pass Frequency Inner Race
• BPFO - Ball Pass Frequency Outer Race
• BSF - Ball Spin Frequency
• FTF - Fundamental Train Frequency

You supply the RPM of the bearing and the program does the rest. The screen also displays those calculations for 10 harmonics and speeds.

Frequencies can be displayed in either

• CPM - Cycles Per Minute
• Hertz

simply by clicking the appropriate radio button.
