If the centre distance (C) is known, belt length or pitch length can be determined as follows: So if you know the distance between the center points of the pulleys, and their diameters, you can calculate the length of belt you need using this formula. Belt Length Calculator. Step 1


It pays to know how to measure a conveyor belt while it's still on the conveyor system using the center-to-center distance formula. The center-to-center distance formula. This conveyor belt measurement formula is one of the most reliable methods for determining the correct length of the replacement conveyor belt you need.

The 5th, 6th, and 7th editions of the Conveyor Equipment Manufacturers' Association Belt Conveyor Design Manual includes several methods to calculate the belt tension required to move bulk materials on a conveyor belt. They are beyond the scope of this short video. These methods include "historical", "basic", and "universal" methods.


Hi everybody...I've been looking for a formula that can calculate the length of a 20" flat belt for a multiple pulley/roller conveyor bed. The conveyor beds vary as to how many rollers and pulleys it consists of. Usually just a tail & nose roller, 2 tracking rollers, screw take-up, drive pulley, and a snub roller. Any information would be much appreciated.
