4-2. Select sprockets, shafts, and bearing units

Select a shaft, bearing, and sprocket that satisfy requirements based on the shaft capacity graphs tables 10 to 24 below, and the type of shafts and corresponding bearing units (refer to product page).

Note) F' tension on the chain width per meter has a limit in some types of bearings (according to the internal diameter of the bearing).

Relation between chain tension (F') per 1 m of chain width and bearing unit support span

1) Relation between bearing support span Y and chain width X
For 40, 50 and 60 square shafts: Approximately Y = X + 150 (mm)

Note) Operating Temperature Range ：-20～80℃

Relation between chain tension (F') per 1 m of chain width and bearing unit support span
