mountings matched angular contact or double row deep groove angular contact bearings are preferred at the other end of the shaft a single row radial bearing may be used as shown in figures 30 and 33 when mounted on taper roller bearings the indirect mounting should be used that is the large ends of the tapered rollers of each bearing should point outward as shown in figures 31 and 32 the thrust load of the pinion is thus absorbed by the bearing adjacent to the pinion and the reverse thrust load will be taken by the opposite bearing in either type of mounting both the gears and thrust bearings should be locked against thrust in either direction this applies to straight bevel and zerol® bevel gears as well as to spiral bevel and hypoid gears it is accepted practice to preload the bearings to remove initial freedom in the mounting the amount of preload depends upon the mounting load and operating speed and should be established by the bearing manufacturer mountings rigid mountings
