S3M pulleys and belts are the best way to transmit power from your motor to drive wheels or a spinning weapon.  Timing belts give better pulley grip than o-rings, which will slip.  We offer an extensive range of sizes and widths to provide options beyond common sizes/widths.  This gives extra freedom when designing a bot.     Our belts are compatible with Fingertech S3M pulleys as well as other 3mm pitch pulleys.   •S3M pitch (3mm high-torque) •Width: 4mm, 6mm & 8mm •Circumferences: 102mm (40T) - 408mm (136T) •Belts are sold individually.
