Pulley & Belt Calculator
Interested in using our S3M Timing Pulleys or Belts?
This useful tool will tell you the center distance between pullies, or if you want a certain center distance, it will tell you what belt size you need based on what pullies you have chosen!
The dropdowns show all of the FingerTech pulley and belt sizes for easy selection.
If you are using sizes we don't sell, simply type the dimesions into the text boxes and ignore the dropdowns. (The calculator even works for different pitch!)
See below for an example and definitions!
