Timing pulleys and belts are the best way to transmit power from your motor to drive wheels or a spinning weapon. 

A range of thirty-two belt sizes allows you to design your robot then pick a belt, rather than the other way around! 
Use with our selection of FingerTech S3M pulleys, or any other 3mm pitch pulley. 

Fingertech's Pulley-Belt Distance Calculator will let you pick from our available pulley and belt sizes and tell you how far apart they will be, OR plug in your desired distance and it will tell you which belt to use.
