If you are out in the middle of the ocean and one of your main propeller shaft bearings starts to rumble, who can you call? Pretty much no one, so use this program to learn how to listen to your bearing.

Includes dozens of sample bearing configurations based on real bearings.

Indicates the features of each bearing:

• # of rollers
• contact angle of bearing races
• FTF - Cage events per rotation of the driver
• BSF - Roller events per rotation of the driver
• BPFO - Ball Passing Frequency / Outer Race = FTF * (# of rollers)
• BPFI - Ball Passing Frequency / Inner Race = (# of rollers) - BPFO
• Shaft Rotation Angle
