Data shared of inner race fracture on 51 RPM conveyor bearing.
Here is some clean data of an inner race fracture from a 51 RPM conveyor bearing on a 12 inch shaft.
This defect was identified and changed out later on a planned outage. BPFI - inner race fracture.
(SFK) 23068CAC Taper Lock bearing. 51 RPM (0.85 Hz).
I enjoy reading everyone else`s data and thought this was a fair one to share as the fault frequencies are very clear.
