Hobbyists, makers, and small workshop operators building conveyors, CNC routers, or custom automation rigs need a pulley that is dimensionally consistent, easy to mount, and available in the exact bore they need — without waiting weeks for a custom order.\u003c\/p\u003e\n\u003cp\u003eThese V-groove aluminum drive pulleys feature a single 10mm-wide V-groove profile machined from aluminum alloy. Outer diameters span 40 mm (~1.57 in) to 80 mm (~3.15 in), with bore (hole diameter) options ranging from 7 mm to 32 mm to suit a wide variety of shaft sizes. Each pulley is sold individually (1 pc per pack) unless a multi-pack variant is selected.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include DIY belt-drive speed reducers, small lathe or drill press pulley replacements, 3D printer or CNC axis drive systems, and light-duty conveyor builds where a compact, corrosion-resistant aluminum pulley is preferred over heavier cast-iron alternatives.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for standard V-belts with a 10mm groove width.
