It carries 30 teeth, a 1 inch bore diameter, and a 4.016 inch hub diameter, with an outside diameter of 7.59 inches. Machined from steel, this sprocket arrives ready to install without additional boring or machining. It is a standard component in mechanical power transmission applications, typically installed by industrial maintenance technicians and mechanical contractors working on conveyor systems, drive trains, and similar chain-driven equipment.\u003c\/p\u003e\n\u003cp\u003eThis sprocket is suited for light to medium-duty power transmission setups that use ANSI No. 60 roller chain. Its finished bore construction makes it appropriate for direct shaft mounting in applications where the bore size matches the shaft exactly. Common installation scenarios include conveyor drives, agricultural equipment drives, and general industrial machinery where a 3\/4 inch pitch chain is specified. The steel construction provides durability in demanding operating environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore design — no additional machining required before installation\u003c\/li\u003e\n  \u003cli\u003e30 teeth with 3\/4 inch chain pitch, compatible with ANSI No. 60 roller chain\u003c\/li\u003e\n  \u003cli\u003eSteel construction for strength and wear resistance in industrial environments\u003c\/li\u003e\n  \u003cli\u003e1 inch bore diameter for direct shaft mounting\u003c\/li\u003e\n  \u003cli\u003e7.59 inch outside diameter and 4.016 inch hub diameter for standard drive configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ANSI No. 60 roller chain at 3\/4 inch pitch.

De-energize and lock out the drive system before mounting or removing sprockets in accordance with applicable OSHA lockout\/tagout procedures. Ensure the shaft is clean and free of burrs before pressing the sprocket into position. Align the sprocket face squarely with mating sprockets to prevent premature chain and tooth wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSprocket Type\u003c\/strong\u003e: Finished Bore\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Teeth\u003c\/strong\u003e: 30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain Pitch\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain Trade Size\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 4.016 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 7.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.44 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171900\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BROWNING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1883438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51540220084530,"sku":"1883438","price":467.28,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b17a73bdb878d3a5968f79f7a1f07fb2_21e94510-bcaf-441a-9391-1ba97df85104.jpg?v=1785849287","url":"https:\/\/voomisupply.com\/products\/browning-1883438-finished-bore-sprocket-30t-3-4-in-pitch","provider":"Voomi Supply","version":"1.0","type":"link"}
