Our specialty Timing Pulleys and Belts are the perfect solution for transmitting power from motors to wheels or shafts.
While O-Rings and round belts will slip under tension, timing belts have teeth that ensure a positive lock to the pulleys.

Ten pulley sizes means there are 55 different ratio combinations to choose from!
Use with FingerTech Timing Belts, or any other 3mm pitch belt.
