Conveyor Belt Calculations
Note: This pitch length is calculated as the theoretical pitch location, in the center of the belt thickness. The actual pitch location varies.

Methods For Measuring an Endless Belt
1. When the belt is on the conveyor
If you are able to wrap your tape measure around the entire belt on the conveyor, you can get an accurate measure of the belt. This would be considered the Outside Circumference(OC). With the belt on the conveyor, it is most likely under tension, so finding the conveyors take up is important in calculating the belts relaxed length.
2.When there is no belt on the conveyor
If you are able to wrap your tape measure around the entire conveyor where the belt would ride, you can get an accurate measure of the belt. This would be considered the Inside Circumference(IC). When Measuring the conveyor like this, it is very helpful to take a measurement with the take up all the way in, and all the way out. These two measurements tell you the acceptable belt length range, which is important when considering tension and tolerances.
3. When you can’t wrap a tape measure around the whole conveyor
When you cant wrap your tape around the conveyor, you can measure it in flat sections. This can be done by marking the belt, and jogging the conveyor until you measure the full length. This measurement would be the Pitch Circumference (PC). With the belt on the conveyor, it is most likely under tension, so finding the conveyors take up is important in calculating the belts relaxed length.
4. When you have an endless belt loose
When measuring a loose endless belt, the method is similar to Method 3, you measure the belt in flat sections. This would also be Pitch Circumference (PC). More detailed instructions for this may be found in the related brochures below.
