4. Determine the theoretical ("exact") and quick estimate bearing defect (rotational) frequencies for bearing NTN 7315, assuming it has 8 balls with a ball diameter of 0.975 in. (Quick estimates: FTF = 0.4xRPM, BSF = 2.6xRPM, BPFO = 4.1xRPM, BPFI = 5.9xRPM or 0.6xNxRPM). The bearings are used with an electric motor operating at 1750 RPM. Bearing specifications are on the back.
