Question: a rotor and shaft assembly for a motor weigh approximately...

Question details

A rotor and shaft assembly for a motor weigh approximately 1142 lbs combined. A radial force of 400 lbs and an axial force of 1830 lbs are also applied at both ends of the bearings. The bearings are 6222 single row deep groove ball bearings. The dynamic load rating (C) is approximately 151 kN. Calculate the equivalent bearing load rating (P) for the bearings and also calculate the bearing life in hours (L10H). The dimensions for the shaft are shown on the drawing. The X radial load factor is .460 and the Y radial load factor is 1.572.
