Makers, engineers, and hobbyists who demand repeatable, backlash-free motion need a pulley that holds tight tolerances across thousands of print hours. The 2GT Synchronous Wheel Step Timing Pulley 32 Teeth BF Type is engineered for exactly that — delivering consistent belt engagement and smooth rotational transfer in demanding motion systems.\u003c\/p\u003e\n\u003cp\u003eThis pulley features a 32-tooth 2GT (GT2) tooth profile machined from aluminum alloy, with a dual-flange (BF-type) design to keep the belt tracking true. Available bore sizes range from 5 mm to 10 mm (approx. 0.20″–0.39″), and belt width compatibility covers both 6 mm and 10 mm (approx. 0.24″–0.39″) GT2 belts. The set-screw clamping hub allows secure shaft mounting without adhesives.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include FDM 3D printer X\/Y axis drives (compatible with popular CoreXY and Cartesian platforms), desktop CNC router feed systems, and lightweight robotic arm joint drives — anywhere a 2GT synchronous belt drive for 3D printer or CNC motion control is required.\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 or closed-loop belts in 6 mm and 10 mm widths.

Common NEMA 17 motors use a 5 mm shaft, while larger NEMA 23 motors typically use an 8 mm or 10 mm shaft.

Most standard FDM 3D printers (e.g., Ender, Prusa-style) use 6 mm wide GT2 belts. Larger-format or higher-torque CNC systems often use 10 mm wide belts for increased load capacity.
