Makers, hobbyists, and small-workshop engineers building or upgrading belt-driven machines need a reliable GT2 pulley that fits their exact shaft and belt width without guesswork. This GT2 32-tooth timing pulley is engineered for repeatable, low-backlash power transmission in demanding DIY and light-industrial applications.\u003c\/p\u003e\n\u003cp\u003eEach pulley features a 32-tooth GT2 tooth profile machined to accept either a 6 mm or 10 mm wide GT2 timing belt. The bore options span 5 mm, 6 mm, 6.35 mm (1\/4 in), 8 mm, and 10 mm to match common motor shaft diameters. The body is typically 20–28 mm in outer diameter depending on bore and belt-width variant, with a compact hub length of approximately 14–18 mm. A set-screw (M3) secures the pulley to the shaft without adhesive.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include GT2 belt drive upgrades for FDM 3D printers (X\/Y axis stepper pulleys), CNC router axis drives requiring a 32-tooth GT2 sprocket, and custom linear-motion or conveyor systems in educational robotics labs and maker spaces.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e \u003cstrong\u003eCompatible with:\u003c\/strong\u003e GT2 timing belts — 6 mm width (2 mm pitch) and 10 mm width (2 mm pitch).

Most desktop 3D printers (e.g., Ender, Prusa i3 style) use 6 mm wide GT2 belts on the X and Y axes.
