The gearbox shown in figure is supported by two tapered roller bearings A and B. The radial support loads and axial load on shaft on the direction of arrow shown on shaft is result of power transmission determined by free body analysis. The radial force carried by the bearing A to be 20 kN and the radial force at the bearing B to be 25 kN . In addition, the outer the axial load applies to shaft in arrow direction is 5 kN . A bearing life of 360 million revolutions is desired with a 90 percent each bearing, Select suitable tapered roller bearings from table.
