This 08B stainless steel simplex roller chain sprocket is engineered for makers, maintenance technicians, and machine builders who need a dependable, corrosion-resistant drive component that installs quickly and holds up in demanding environments.\u003c\/p\u003e\n\u003cp\u003eEach sprocket is machined from stainless steel and supplied with a pilot bore ready for custom boring to your shaft size. The 08B designation conforms to ISO 606 standards with a 1\/2\" (12.7 mm) pitch. Tooth counts range from 10T to 48T across 25 variants, covering pitch circle diameters from approximately 51 mm (2.0\") for 10T up to approximately 194 mm (7.6\") for 48T. Hub dimensions and bore capacity vary by tooth count — see variant options for exact figures.\u003c\/p\u003e\n\u003cp\u003eTypical applications include food-grade conveyor drives where stainless steel is required for washdown resistance, light industrial automation with 08B simplex roller chain, agricultural equipment replacement sprockets, and custom DIY chain drive projects requiring a pilot bore

sprocket is designed for ISO 606 \/ DIN 8187 08B-1 Simplex Roller Chain with a 1\/2\" (12.7 mm) pitch and a 5\/16\" (7.94 mm) roller diameter. Do not use with 40 ANSI chain — while the pitch is the same, the roller width and plate dimensions differ and the chain will not mesh correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I choose the right tooth count for my application?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThe tooth count determines your drive ratio. Divide the driven sprocket teeth by the driver sprocket teeth to get the reduction ratio. For example, a 10T driver paired with a 30T driven sprocket gives a 3:1 reduction. Choose a smaller tooth count for higher speed output and a larger tooth count for more torque. Using at least 17T on the driver sprocket reduces chain wear and noise.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat does pilot bore mean and how do I size the bore?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eA pilot bore sprocket is supplied with a small starter bore (typically 10–16 mm depending on tooth count) that must be machined by a lathe or boring machine to match your shaft diameter.
