When we try steel belts, we set pulley diameter first.
Pulley diameter = Belt thickness x 700
For instance,
when belt thickness is 0.1mm,
pulley diameter is 70mm.
This is a norm.
Depending on applications,
It may be x 800, or x600, or x400.
The picture below, in our standard conveyor,
Pulley diameter 50mm=Belt thickness 0.15mm x about 350.
