Conveyor Belt Load Carrying Calculation Belt drives are a means of transferring power between rotating shafts (Fig 1). If we need to calculate the distance between the centres of the two pulleys, then we can use the following calculations to approximate this. The diameters of the pulleys are 15 and 30 cm, and you want the distance between them to be 1.5 meters. It also means that if a roller is having length 500mm is given load-carrying capacity as 50Kg, it implies that you can put a load on the 500mm equally and at once. Belt Speed Calculator These calculation tools are to provide product selection ONLY and final application suitability is the sole responsibility of the user.
