Makers, hobbyists, and small-machine builders who rely on ANSI 10A (#50) roller chain need a sprocket that holds tight tolerances and stays true under load — without hunting down industrial suppliers or paying industrial prices.\u003c\/p\u003e\n\u003cp\u003eThis 10A roller chain drive sprocket is machined from carbon steel with a natural or lightly finished surface, sized to mesh precisely with standard ANSI 10A (5\/8\" pitch) roller chain. The flat-plate (no-hub) profile keeps the assembly compact. Tooth counts range from 10T to 20T, with bore and outer diameter scaling accordingly — typically 30–90 mm (1.2\"–3.5\") OD depending on tooth count. Each sprocket ships individually (1 pcs) or in a 10-piece pack for workshop stock.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include go-kart and mini-bike final drives where a 10A sprocket swap changes gear ratio without a full drivetrain rebuild, conveyor and feeder systems in light industrial or maker-space settings that run ANSI #50 chain, and custom chain-drive automation rigs — CNC axis drives, rotary indexers, or motorized camera sliders — where a flat sprocket wheel keeps the profile slim.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e \u003cstrong\u003eCompatible with:\u003c\/strong\u003e ANSI 10A \/ #50 Roller Chain — 5\/8\" (15.875 mm) pitch, 3\/8\" (9.53 mm) roller diameter.

Divide the driven sprocket teeth by the drive sprocket teeth to get the ratio. A smaller drive sprocket (fewer teeth) increases torque and reduces output speed; a larger one does the opposite. For go-karts, 10T–13T drive sprockets are common for higher top speed, while 15T–20T suits torque-heavy or low-speed applications.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWill this sprocket fit my existing #50 roller chain?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes — ANSI 10A and #50 are the same chain standard.
