Fingertech S3M Timing Belt
$2.50
We’re pleased to offer Fingertech belts to match our timing pulleys. Timing pulleys and belts are the best way to transmit power from your motor to drive wheels or a spinning weapon.
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 thirty-two belt sizes allows you to design your robot then pick a belt, rather than the other way around!
Use with our FingerTech S3M pulleys, or any other 3mm pitch pulley.
- S3M pitch (3mm high-torque)
- Width: 4mm
- Circumferences: 120mm (40T) – 408mm (136T)

Specifications
Fingertech’s 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. Our pulleys will hold up best under the rigors of combat.
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).
