Built from steel, it features 13 teeth and a 5\/8-inch chain pitch, with an outside diameter of 2.91 inches. The plain bore design accepts a bore range from 5\/8 inch minimum up to 1-5\/16 inches maximum, allowing the installer to finish-bore and keyway the hub to the exact shaft dimension required. This sprocket suits conveyor systems, machinery drives, and other power transmission assemblies where a field-bored component is preferred over a fixed-bore or bushed design. It is typically installed by millwrights, maintenance mechanics, or industrial technicians.\u003c\/p\u003e\n\u003cp\u003eThis sprocket is suited for light-to-medium duty power transmission equipment in manufacturing, material handling, and industrial maintenance environments. The B-series bushing designation and plain bore configuration make it a practical choice when precise shaft sizing is determined in the field. It is compatible with standard ANSI No. 50 roller chain and is sold individually, making it suitable for both new installations and single-component replacements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e13-tooth, 5\/8-inch pitch configuration matched to ANSI No. 50 roller chain\u003c\/li\u003e\n  \u003cli\u003ePlain bore design allows field finishing to exact shaft specification\u003c\/li\u003e\n  \u003cli\u003eBore range from 5\/8 inch to 1-5\/16 inches maximum\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in industrial drive applications\u003c\/li\u003e\n  \u003cli\u003e2.91-inch outside diameter in a compact profile\u003c\/li\u003e\n  \u003cli\u003eB-series bushing series designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ANSI No. 50 standard roller chain at 5\/8-inch pitch.

The shaft and all connected drive components must be fully de-energized and locked out before installation. The plain bore must be finish-bored, reamed, and keyseated to match the shaft before mounting. Verify sprocket alignment and chain tension after installation per the equipment manufacturer's drive design specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Teeth\u003c\/strong\u003e: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain Pitch\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain Trade Size\u003c\/strong\u003e: No. 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.91 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSprocket Type\u003c\/strong\u003e: Minimum Plain Bore\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Series\u003c\/strong\u003e: B\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: 0.95 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: 1122670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51538808209714,"sku":"1122670","price":76.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4bf6c1fd7694054a2e080cabdfe10d3.jpg?v=1785827093","url":"https:\/\/voomisupply.com\/products\/browning-1122670-min-plain-bore-sprocket-13-teeth-5-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
