Abstract
A method for predicting bearing failure of a differential bearing including an inner race, an outer race, and a plurality of rolling elements positioned between the inner and outer race, the method includes coupling a measuring apparatus comprising at least one of a strain gage and an accelerometer to the differential bearing, coupling a cable to the measuring apparatus, wherein the cable is adapted for passage through a rotating component, and coupling a transmitter to the cable, wherein the transmitter is configured to transmit a plurality of signals from the measuring apparatus to a remote location to facilitate predicting a failure of the differential bearing.
