The radial runout of root clearance on a gear set. - YouTube

The shell is sometimes split into two halves. The bearing shell is fitted tightly into its static housing to stop it revolving with the shaft. For simple rotation applications, journal bearings are designed to be parallel within close limits (about 0.1 mm), thereby avoiding excessive loads. A simple journal bearing is shown in Fig. 6.6.

Journal Bearings and Their Lubrication

The clearance changes with the expansion or contraction of the bearing rings. The axial clearance is the total amount that one ring can be displaced relative to the other in an axial direction. In ball bearings, as the radial clearance increases, the axial clearance increases as well. ...

Design of Diametral Clearance for Plain Bearings ...

RING AND PINION BACKLASH.- The ring and pinion backlash refers to the amount of space between the meshing teeth of the gears. Backlash is needed to allow for heat expansion . As the gears operate, they produce friction and heat. This makes the gears expand, reducing the clearance between the meshing teeth of the gears.
