11-34 The figure shown is a geared counter shaft with an overhanging pinion at C. Select an angular contact bearing from Table 11-2 for mounting at O and an 02-series

cylindrical roller bearing from Table11-3 for mounting at B. The force on gear A is FA = 600 Ibf, and the shaft is to run at a speed of 420rev/min. Solution of the statics problem gives force of bearings against the shaft at O as RO = -387j +467k Ibf, and at B as RB = 316j – 1615k Ibf. Specify the bearings required, using an application factor of1.2, a desired life of 40,000 hours, and a combined reliability goal of 0.95, assuming distribution data from manufacturer 2 in Table 11-6.
