Makers, engineers, and desktop-CNC builders who rely on 2GT belt systems need a 36-tooth synchronous wheel that holds tight tolerances across every axis — whether they're dialing in a Reprap extruder or tuning a laser-cutter gantry.\u003c\/p\u003e\n\u003cp\u003eThis 2GT 36T timing pulley is machined from aluminum alloy with a natural or anodized finish. The pulley body accommodates a 10 mm wide 2GT (GT2) belt and is available with bore diameters ranging from 5 mm to 12 mm (approximately 0.20 in to 0.47 in), covering the most common motor shaft sizes used in hobby and light-industrial automation. A set-screw hub locks the pulley firmly to the shaft without adhesives.\u003c\/p\u003e\n\u003cp\u003eTypical applications include Reprap and CoreXY 3D printer X\/Y axis drives, desktop CNC router and laser-engraver gantry systems, and small-scale robotics or conveyor belt mechanisms where a 2GT 36-tooth synchronous wheel provides the torque-to-speed ratio needed for smooth, repeatable positioning.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard 2GT \/ GT2 open-loop and closed-loop timing belts with 10 mm width.
