Pulley diameters shown apply to belts operating at over 60% of maximum allowable working tension
Diameters of all pulleys must be reduced by 20% where belts are operating at less than 60% of allowable working tension
For belts at less than 30% of allowable tension, the diameters of Type A pulleys can be further reduced by
Working tensions assume a reasonably well maintained plant, with infrequent controlled starts and moderate impact
For more severe service, ie: poor loading, frequent loaded or DOL starts, short time cycles then reduce the above values by 15%
For extreme service, ie: poorly maintained plant, chemical aggression, bad loading and starting, then reduce the above values by 30%
