Machined from steel, it features 15 teeth, a 1 inch bore diameter, and a 2.891 inch hub diameter with a 3.98 inch outside diameter. The finished bore design means the bore is already machined to final size, eliminating the need for secondary boring operations before installation. This sprocket is a standard power transmission component suited for conveyor drives, industrial machinery, and HVAC equipment drive systems where chain drive assemblies are specified.\u003c\/p\u003e\u003cp\u003eThis sprocket fits applications requiring an ANSI No. 60 roller chain drive. The 3\/4 inch pitch and 15-tooth configuration produce a specific drive ratio and chain speed that must be matched to the mating sprocket and chain on the driven assembly. Typical installations include light-to-medium duty industrial conveyor systems, pump drives, blower drives, and similar chain-driven mechanical equipment in commercial and industrial settings. Licensed mechanical contractors and industrial maintenance technicians are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFinished bore at 1 inch — ready to install without additional machining\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in mechanical drive applications\u003c\/li\u003e\n\u003cli\u003e15 teeth with 3\/4 inch pitch, compatible with ANSI No. 60 roller chain\u003c\/li\u003e\n\u003cli\u003e2.891 inch hub diameter provides a secure mounting interface\u003c\/li\u003e\n\u003cli\u003e3.98 inch outside diameter suits compact drive envelope requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ANSI No. 60 roller chain at 3\/4 inch pitch. The bore diameter is fixed at 1 inch; the mating shaft must be 1 inch in diameter to achieve proper fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanical or industrial maintenance technician. De-energize and lock out all power to the drive system before removing or installing any sprocket. Verify that the shaft diameter matches the 1 inch finished bore before pressing or sliding the sprocket onto the shaft, and secure with a properly sized key and set screw as required by the shaft configuration. Align the sprocket face with the mating sprocket within acceptable tolerances to prevent accelerated chain and sprocket wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChain Pitch\u003c\/strong\u003e: 3\/4 inch (0.7500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChain Trade Size (ANSI)\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: 2.891 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.98 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: 2.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1129261\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51540271989042,"sku":"1129261","price":94.08,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b17a73bdb878d3a5968f79f7a1f07fb2_35860fa0-2dda-4c28-8340-679fd0c9539a.jpg?v=1785850874","url":"https:\/\/voomisupply.com\/products\/browning-1129261-finished-bore-sprocket-15t-3-4in-pitch","provider":"Voomi Supply","version":"1.0","type":"link"}
