Abstract: A method for determining real time load values experienced by a bearing includes providing a bearing with an inner race, an outer race, and a plurality of rolling elements disposed therebetween. Mounting a plurality of strain gages to the bearing, and collecting data of the strains measured under a plurality of known load conditions. Correlating the strains measured at each strain gage position to the load at that position for each of the plurality of load conditions to develop a first equation for each strain gage position defining the load as a function of the strain measured. Mounting the bearing to a machine, using the machine under loaded conditions, and collecting the strain gage data produced. Using the equations for each strain gage position to convert the strain measured into a load. Summing the loads experienced by the bearing to determine the total load being experienced by the bearing.
