This 06B flat chain drive sprocket is engineered for makers, maintenance technicians, and DIY builders who need a reliable, drop-in replacement or upgrade for standard 06B roller chain applications.\u003c\/p\u003e\n\u003cp\u003eEach sprocket is machined from carbon steel with a flat-plate hub profile. The tooth form is cut to ISO 606 \/ BS 228 standards for 06B chain, which runs a 3\/8\" (9.525 mm) pitch. Available tooth counts span 10T through 42T, with outer diameters ranging from approximately 38 mm (1.50\") on the 10T up to approximately 130 mm (5.12\") on the 42T. Bore diameter and keyway dimensions vary by tooth count — see variant options for confirmed bore specs.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include light conveyor drives where a compact sprocket-and-chain loop replaces belt systems, bicycle or e-bike jackshaft builds requiring a specific gear ratio, and small agricultural or workshop machinery needing a replacement drive wheel.
