Machined from steel, this 45-tooth sprocket arrives ready to install with a 1 inch finished bore — no secondary boring or reaming required. The 3.5 inch hub diameter and 7.45 inch outside diameter are sized for typical industrial and mechanical drive applications. It is installed by mechanical contractors, maintenance technicians, and drive system specialists working on conveyor, pump, and general power-transmission equipment.\u003c\/p\u003e\n\u003cp\u003eThis sprocket suits light-to-medium duty roller chain drive systems that use No. 40 chain. Common install scenarios include conveyor drives, auger assemblies, pump drive trains, and other equipment requiring a precise finished bore with no additional machine work. The fixed 1 inch minimum and maximum bore diameter means this sprocket is specifically suited to 1 inch shafts and is not intended for re-boring to alternate shaft sizes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at exactly 1 inch — installs directly onto a 1 inch shaft without additional machining\u003c\/li\u003e\n  \u003cli\u003e45 teeth on 1\/2 inch pitch for use with standard No. 40 roller chain\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in industrial drive applications\u003c\/li\u003e\n  \u003cli\u003e7.45 inch outside diameter with 3.5 inch hub diameter for balanced load distribution\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit with no minimum order requirement beyond one piece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ANSI No. 40 roller chain on a 1\/2 inch pitch.

Disengage and lock out all power to the drive system before mounting or removing sprockets. Verify shaft diameter matches the 1 inch finished bore before installation, and ensure proper chain alignment and tension after assembly per the equipment manufacturer's drive specifications. Follow applicable ANSI and OSHA machine-guarding requirements for exposed roller chain drives.\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: 45\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain Trade Size\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain Pitch\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\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: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 7.45 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: 4.88 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: 1134600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542437167410,"sku":"1134600","price":158.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f70d7741bda7acb4fedc6fa0c817efc0.jpg?v=1785900468","url":"https:\/\/voomisupply.com\/products\/browning-1134600-finished-bore-sprocket-45t-1-2in-pitch","provider":"Voomi Supply","version":"1.0","type":"link"}
