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.
  • S3M pitch (3mm high-torque)
  • Belt Width (maximum) : 8mm
  • Size: 15 Teeth
  • Bore: 3mm - Can be drilled up to 7.14mm (9/32")
  • Flange Diameter: 18.2mm (0.72")
  • Pulley Width: 11.5mm (0.45")
  • Includes 4-40 setscrew for fastening to shaft.  Make sure your shaft has a flat spot. Make one yourself with a file if you have to!  Setscrews do not hold well on round shafts.
  • Setscrew requires 0.050" hex wrench
