FingerTech S3M Timing Pulley 15T Dual

Fingertech 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 FingerTech Timing Belts, or any other 3mm pitch belt.
