Notice in the mount-ing shown in Figure 11the left-hand bearing isnot held, but the right-hand bearing is held tostabilize the shaft againstend-wise motion. Themounting is exceedinglysimple, efficient and re-liable.^ Figure 14 shows a typi cal clutch mounting show-ing the location of theball bearings. The selfaligning radial ball bear-ing is rapidly becoming the Continued on page 187. riGi i 184 Volume XXI
