An 02 series deep groove ball bearing supports a radial load of 2.16 kN and an axial load of 2.02 kN. The life of the bearing, based upon 95 % survival is to be 2.19 kHrs with the inner ring rotating at 110 RPM. Assume an application factor of 1.3 and that Manufacturer 2 will supply the
bearing.
Stress analysis on the shaft at the location of the bearing has determined that a 20 mm shaft diameter is adequate to meet the required shaft factor of safety. Select a suitable bearing that would meet the bearing life criteria and minimize the change in the shaft’s diameter.
