Engineers, makers, and repair technicians who rely on GT2 belt-driven motion systems need a drop-in 15-tooth synchronous wheel that holds tight tolerances without play. This 15T 2GT timing pulley is designed for exactly that — delivering consistent, backlash-resistant motion in demanding automated systems.\u003c\/p\u003e\n\u003cp\u003eEach pulley features a 15-tooth GT2 (2mm pitch) tooth profile machined to mesh cleanly with standard GT2 timing belts. Available bore sizes span 3mm, 3.175mm (1\/8\"), 4mm, and 5mm, with slot widths of 7mm (fits 6mm-wide belts) and 11mm (fits 10mm-wide belts). The compact wheel diameter is typically 9–12mm OD depending on bore, keeping the footprint minimal for tight build volumes.\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 belt drives, and lightweight robotic arm joint actuators — anywhere a reliable 2GT synchronous wheel is needed for 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 GT2 \/ 2GT timing belts — 6mm-wide belts with 7mm slot width variants; 10mm-wide belts with 11mm slot width variants.
