Figure 1 shows a cheap, solid cast-iron box used for com-
paratively small and less important shafts. Dimensions, suita-
ble for bearings from one to two inches in diameter, are given
in the following table :

Figure 2 shows a babbitted split box suitable for shafts
from one to four inches in diameter, and running at a com-
paratively slow speed.

Figure 3 shows the same general design of box as Figure
2, excepting that the bearing is longer and the base wider.
This box is more suitable for comparatively high-speed shafts.
