Name: Mechanical Looseness
Description: Note the evenly spaced harmonics with no frequency content between them in the FFT and the evenly spaced impacts which are almost “clones” of each other in the Time Series. A very clear indication of mechanical looseness. FFT View Time Series View

Note the evenly spaced harmonics with no frequency content between them in the FFT and the evenly spaced impacts which are almost “clones” of each other in the Time Series.

A very clear indication of mechanical looseness.
