Makers, CNC builders, and workshop engineers who rely on XL-pitch timing systems need a pulley that holds tight tolerances across every revolution. This XL 50-tooth timing belt pulley is engineered for exactly that — delivering consistent, backlash-free rotation in demanding DIY and light-industrial drive systems.\u003c\/p\u003e\n    \u003cp\u003eEach pulley is machined from aluminum alloy with a natural or anodized finish, featuring 50 teeth on the XL pitch profile (5.080 mm \/ 0.200 in pitch). The bore diameter ranges from 10 mm to 25 mm (0.39 in to 0.98 in) to suit a wide variety of shaft sizes. Two style options are available: with flanges (Mit Zähnen) to keep the belt tracked, or without flanges (Ohne Zähne) for open-ended drive configurations. Compatible belt width is 11 mm (approximately 0.43 in).\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include CNC router X\/Y-axis drives requiring precise positioning, 3D printer extruder and gantry belt systems, and custom conveyor or automation rigs where an XL 50-tooth timing pulley for 11mm belt provides reliable, repeatable motion at moderate speeds.\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 Fits standard XL-pitch timing belts, 11 mm (0.43 in) wide.
