WebJan 4, 2024 · There are four typical bearing fault frequencies: FTF, BSF, BPFO and BPFI. FTF — Fundamental train frequency (Cage rotational frequency) BSF — ball (or rolling element) spin frequency. WebEach of these bearings has 4 fault frequencies: Fundamental Train Frequency (FTF) Ball Pass Frequency on the Inner race (BPFI) Ball Pass Frequency on the Outer race (BPFO) Ball Spin Frequency (BSF). The equations to determine the frequencies can be found by an internet search for bearing frequencies. WebThese four fault frequencies are commonly termed: BPFO - Ball Pass Frequency, Outer Race BPFI - Ball Pass Frequency, Inner Race BSF - Ball Spin Frequency FTF - Fundamental Train Frequency.
