Whether you're maintaining a CoreXY build, a belt-driven gantry, or a CNC axis, these belt torsion springs are engineered to deliver steady, repeatable tension without manual re-adjustment. They are suited for makers, engineers, and workshop professionals who demand precision from their motion systems.\u003c\/p\u003e\n    \u003cp\u003eEach spring is manufactured from hardened steel wire with a consistent coil geometry. Available in two belt-width configurations — 6mm (~0.24 in) and 10mm (~0.39 in) — these torsion springs are compact enough to fit within standard belt tensioner housings. Wire diameter is typically 0.5–1.0mm (0.020–0.039 in), with an outer coil diameter in the range of 4–12mm (0.16–0.47 in) depending on variant.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include belt tensioner assemblies on FDM 3D printers (e.g., Ender, Voron, RatRig), CNC router X\/Y axis belt drives, and custom motion platforms requiring passive spring-loaded tension. Long-tail applications include \"3D printer belt tensioner spring replacement\", \"CNC belt drive torsion spring\", and \"GT2 belt tension spring for CoreXY\".\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    Compatible with 6mm and 10mm wide timing belts (GT2, T5, HTD, and similar profiles).
