Machined from steel, this sprocket features 16 teeth, a 3\/4 inch finished bore diameter, and a 2.578 inch hub diameter. The outside diameter measures 3.52 inches. The finished bore is ready for direct shaft installation without additional machining, making it a straightforward drop-in component for mechanical power transmission applications in HVAC, industrial, and equipment drive systems. Licensed millwrights, maintenance technicians, and mechanical contractors are the typical installers.\u003c\/p\u003e\u003cp\u003eThis sprocket is suited for light-to-medium duty roller chain drive assemblies using ANSI No. 50 chain. Common applications include conveyor drives, blower drives, pump drives, and other rotary power transmission setups where a standardized finished bore sprocket is required. Its steel construction makes it appropriate for both indoor and moderate-duty industrial environments. The fixed 3\/4 inch bore means no secondary boring or bushing is required when the shaft diameter matches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFinished bore eliminates need for additional machining before installation\u003c\/li\u003e\n\u003cli\u003e16-tooth count suitable for standard gear ratio drive configurations\u003c\/li\u003e\n\u003cli\u003eCompatible with ANSI No. 50 roller chain at 5\/8 inch pitch\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in mechanical drive applications\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 3.52 inches fits common drive assembly envelopes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ANSI No. 50 roller chain with a 5\/8 inch pitch.

Disengage and lock out all power to the drive system before removing or installing any sprocket. Ensure the mating shaft is clean and free of burrs before pressing or keying the sprocket into position. Verify chain tension and sprocket alignment after installation per the equipment manufacturer's specifications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Teeth\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChain Pitch\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChain Trade Size\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 2.578 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.52 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: 1.56 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171900\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: 1128859\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51544444371250,"sku":"1128859","price":141.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa52f0df2d341dc59cd8c0347771dbc5.jpg?v=1785926729","url":"https:\/\/voomisupply.com\/products\/browning-1128859-finished-bore-sprocket-16t-5-8in-pitch","provider":"Voomi Supply","version":"1.0","type":"link"}
