BEARING MOUNTINGS
Horizontal shaft

1 The basic methods ofmounting illustrated in Figs. 22.3(a) and 22.3(b) are designed to suit a variety ofload and rotation
conditions. Use the principles outlined and adapt these mountings to suit your particular requirements.
2 The type of mounting may be governed more by end-float or thermal-expansion requirements than considerations of
loading and rotation.
