How to Measure a Conveyor Belt?

Well, folks the simplest way to do this. Measure both pulley diameters. Measure the center of the shaft or pulley to the other center of the shaft or pulley. Simply calculate, Center to Center multiply that by two. Write that down somewhere, not all of us have a Steel trap for memory. Multiply your pulleys by pi (3.14). If they are the same simply add. For example, you have 45" centers, 4" pulley diameter on both ends. Example: 45 X 2 = 90. 4 X 3.14 =12.56 Simply add 90 + 12.56 = 102.56 Total length needed on you belt is 102.56" Or 102-1/2" long. Of course before you order you will know to measure the width of your belt.
There you have it! Like they say in the business, "It's not rocket science!" If you ask our hardworking guys in the back (Warehouse that is.) "Measure twice, cut once."

( For the engineers! Although I know you don't have time to be on the internet looking for this kind of stuff.)
L= belt length
D= head pulley diameter in inches
d= tail pulley diameter in inches
C= center distance in inches

A. Two pulleys of equal diameter. L= [(D+d) / 2] x 3.14 + (2 x C)
B. Two pulleys, different diameters. L=[(D+d) / 2] x 3.14 + 2C + [(D-d) / 4C]

Thank you very much for your time!
