FingerTech S3M Timing Pulley, 15T - 1/8" Bore for Beater Bar Kit

This is a drop in replacement for the 15T pulley in the 3lb Beater Bar Kit.  It's already bored out to 1/8' for the weapon motor shaft.  

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

A range of ten pulley sizes means there are 55 different ratio combinations to choose from! Use with our selection of FingerTech timing belts, or any other 3mm pitch belt (4mm wide or less).
