CONVEYOR PULLEY SELECTION GUIDE

Belt tension measures the degree to which the conveyor belt is stretched or held taut and is typically measured in pounds per inch width (PIW). Conveyor pulleys and shafts of a larger diameter are better equipped to handle elevated levels of belt tension. Belt tension is applied to the conveyor system by the following sources:
