S3M Timing Belt 396mm, 132T, 4mm width

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 & 8mm•Circumferences: 120mm (40T) - 408mm (136T).Try our Belt and Pulley Calculator!  Calculate your results for belt size, center to center distance or even pully sizes.  It supports manual entry of pulley sizes if using sizes we don't stock.  Available Sizes and Widths120mm, 40T Length:  4mm width129mm, 43T Length:  4mm width135mm, 45T Length:  4mm width138mm, 46T Length:  4mm width141mm, 47T Length:  4mm width144mm, 48T Length:  4mm width147mm, 49T Length:  4mm width150mm, 50T Length:  4mm width153mm, 51T Length:  4mm width159mm, 5
