The 20-Tooth 3GT (GT2-3M) Timing Pulley seamlessly engages with 3GT (GT2-3M) timing belts, providing reliable power transmission without slippage. Designed with a 1/4" (6.35mm) bore, it is compatible with NEMA 23 stepper motors and accommodates belts up to 6mm wide. This makes it an ideal choice for custom builds such as CNC machines, 3D printers, and automated linear actuators, where precise motion control is required.
