It features a 1-inch bore with a 1\/4-inch keyway width and 1\/8-inch keyway depth, allowing secure shaft-to-sprocket coupling with a keyed shaft. The outside diameter measures 4.125 inches, and the bushing is rated for a maximum torque of 348 inch-pounds. Constructed from iron, this bushing provides durable, long-term performance in industrial and mechanical drive applications. Licensed millwrights, maintenance mechanics, and industrial service technicians are the typical installers of this component.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for light-to-medium power transmission drives in commercial and industrial settings. It belongs to the Q1 bushing series and is compatible with split taper sprockets and sheaves that accept a Type Q bushing. The 3\/8 x 1-1\/4 thread size on the flange screws is standard for this series. Typical applications include conveyor drives, fan drives, pump drives, and other belt or chain drive assemblies where a reliable, removable shaft connection is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType Q split taper design allows easy installation and removal without damage to the shaft or hub\u003c\/li\u003e\n\u003cli\u003e1-inch bore with 1\/4-inch x 1\/8-inch keyway for positive keyed shaft engagement\u003c\/li\u003e\n\u003cli\u003e4.125-inch outside diameter fits standard split taper sprocket and sheave hubs\u003c\/li\u003e\n\u003cli\u003eRated to 348 inch-pounds maximum torque for reliable power transmission\u003c\/li\u003e\n\u003cli\u003eIron construction provides strength and durability in industrial environments\u003c\/li\u003e\n\u003cli\u003e3\/8 x 1-1\/4 flange thread size matches standard Q-series hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with split taper sprockets and sheaves that accept a Type Q bushing in the Q1 bushing series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal should be performed by a qualified millwright or maintenance mechanic familiar with split taper bushing systems. Before installation, de-energize and lock out the drive system per NFPA 70E and OSHA 1910.147 lockout\/tagout procedures. Clean the bore, shaft, and mating hub surfaces before assembly, and apply a light lubricant to the bushing bore and shaft as recommended by standard practice. Do not use impact tools to drive the bushing into the hub, as this can damage the taper seat and affect concentricity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Split Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Series\u003c\/strong\u003e: Q1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Q\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway Depth\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8 x 1-1\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Torque\u003c\/strong\u003e: 348 inch-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171600\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: 1078864\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542266118450,"sku":"1078864","price":109.16,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b38a5eda274dcf18496cc514dd2fd6b4.jpg?v=1785896801","url":"https:\/\/voomisupply.com\/products\/browning-1078864-type-q-split-taper-sprocket-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
