When a worn or mismatched sprocket causes chain skip, premature wear, or unexpected downtime, finding an exact-spec replacement becomes urgent. Whether you are a mechanical engineer, a workshop technician, or a hands-on maker maintaining conveyor systems, go-karts, or light industrial machinery, these 06C sprocket wheels are sized and hardened to drop straight into your drivetrain.
Each sprocket is machined from 45# medium-carbon steel and heat-treated for surface hardness. The tooth profile conforms to the 06C (also referenced as ANSI #35) roller chain standard with a pitch of 9.525 mm (3/8 in). Tooth counts range from 10 to 25, covering bore diameters that typically span 6–20 mm depending on the model selected. The matching 06C roller chain and connecting links are also available as variant options on this listing.
Typical use cases include go-kart and mini-bike final drives requiring a compact 3/8-inch pitch sprocket, light conveyor and feeder systems in workshop automation, and small agricultural or garden equipment chain drives where a replacement 06C sprocket wheel with a specific tooth count is needed for precise gear-ratio tuning.

The tooth count determines your drive ratio. Divide the driven sprocket teeth by the drive sprocket teeth to get the reduction ratio. A smaller drive sprocket (fewer teeth) paired with a larger driven sprocket gives more torque and less speed. For go-karts, a 10–12 tooth drive sprocket is common; for conveyors, match the ratio to your required output RPM.
Yes. The 06C standard is dimensionally equivalent to ANSI #35. Both share a 9.525 mm (3/8 in) pitch and a 6.35 mm roller diameter, so these sprockets will mesh correctly with any standard #35 or 06C roller chain.
Bore diameter varies by tooth count and is not uniform across all models. Please refer to the variant detail page or contact us to confirm the bore size for your selected tooth count before ordering. We recommend measuring your shaft diameter first.
45# medium-carbon steel is a widely used engineering material for sprockets and gears. After heat treatment, the tooth surface achieves sufficient hardness to handle the cyclic loading of roller chain drives in light-to-medium duty applications such as go-karts, conveyors, and small machinery. For heavy-duty industrial applications with continuous high-load cycles, consult us for material options.
The sprocket has a surface treatment that provides basic oxidation resistance for typical workshop and sheltered outdoor use. For prolonged outdoor or wet environments, we recommend applying a chain lubricant or light grease to both the sprocket teeth and the roller chain to extend service life and prevent surface rust.
Yes. This listing includes 06C standard roller chain and 06C intensified roller chain in 1.5-meter lengths, as well as full buckle connecting links (4 pcs) and half buckle connecting links (2 pcs) — all selectable as variants. This lets you source the sprocket, chain, and hardware in a single order.
It depends on your shaft diameter. Many sprockets in this range come with a standard pilot bore that may require finish machining (reaming or boring) to match your exact shaft size and keyway. Contact us with your tooth count and shaft diameter to confirm whether the as-supplied bore fits directly or requires machining.
