11-32 The figure shown is a geared countershaft with an overhanging pinion at C. Select an angular- contact ball bearing from Table 11-2 for mounting at O and an 02-series cylindrical roller bearing from Table 11-3 for mounting at B. The force on gear A is FA-600 lbf, and the shaft is to run at a speed of 420 rev/min. Solution of the statics problem gives force of bear- ings against the shaft at O as Ro--387] 467k lbf, and...

Shown in the figure is a gear driven squeeze roll which mates with an idler roll (not shown). The roll is designed to exert a normal force of 30 lb/in of roll length and a pull of 24 lb/in on the material being processed. The roll speed is 300 rev/min and an L10 life of 30 kh is desired. Use an application factor for poor bearing seals and commercial gearing. Select a pair of radial contact 6300-series medium, deep groove...

find the LS and SS for the fit and the LH and SH for the hole.
Fits are all SHAFT BASIS METRIC but the shaft and hole diameters can not be used right out of the table. This is because the 3mm shaft tolerance does not match. You will need to lookup the "Fit" from the table, and then use the LS (Largest Shaft) and SS (Smallest Shaft)...
