Engineers, fabricators, and serious DIYers working with #80 roller chain drives need a sprocket that holds tight tolerances across the full load range — not one that introduces slop from day one.\u003c\/p\u003e\n    \u003cp\u003eThese 16A chain drive flat sprockets are machined to suit a 1\" pitch (25.4 mm) roller chain, conforming to the ISO 606 \/ ANSI #80 standard. Available in 41 tooth-count options from 10T through 50T, each sprocket features a flat-plate body profile with a precision-bored center hub. Outer diameter scales with tooth count, ranging from approximately 100 mm (3.94\") on the 10T up to approximately 410 mm (16.14\") on the 50T. Bore diameter is sized per variant — see variant options for exact bore dimensions.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include industrial conveyor line drives requiring consistent chain engagement, agricultural and material-handling equipment upgrades where replacement sprocket availability matters, and custom power-transmission builds — such as go-kart rear axle drives, winch systems, and chain-reduction gearboxes — where selecting the correct 16A flat sprocket tooth count determines final drive ratio and output torque.\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 ISO 606 \/ ANSI #80 roller chain with 1\" (25.4 mm) pitch.
