For the shaft application defined in perform a preliminary specification for tapered roller bearings at C and D. A bearing life of 10 8 revolutions is desired with a 90 percent combined reliability for the bearing set, assuming distribution data from manufacturer 1 in Table 11–6. Should the bearings be oriented with direct mounting or indirect mounting for the axial thrust to be carried by the bearing at C? Assuming bearings are available with K = 1.5, find the required radial rating for each bearing. For this preliminary design, assume an application factor of one.
