Bearing Tones

Four bearing tones are defined for rolling element bearings: The Fundamental Train Frequency, abbreviated FTF, is the rotation rate of the cage or ball retainer. It is usually about 0.4 times the running speed. The FTF itself is seldom seen in a vibration spectrum because the cage is not very massive and caries essentially no load.
