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.
This double-wide pulley allows TWO belts - one to a front and one to a rear wheel, or two to your weapon for extra strength. Use with our selection of
FingerTech timing belts, or any other 3mm pitch belt (4mm wide or less).
The setscrew is sunken beneath the belt teeth so there is no need for a hub to stick out the side!
