Manufactured from iron, this Q1 series bushing features a 1.375 inch bore diameter and an outside diameter of 4.125 inches. The keyway measures 5\/16 inches wide by 5\/32 inches deep, providing positive key engagement for reliable torque transfer up to 348 inch-pounds. The split taper design allows for easy installation and removal on taper-bored hubs without requiring specialized pulling equipment. HVAC and industrial maintenance technicians install this bushing type on belt-drive blower assemblies, fan systems, and general power transmission applications.\u003c\/p\u003e\u003cp\u003eThe BROWNING 1078930 is suited for residential and commercial mechanical systems where split taper sheaves or sprockets are used. The Q bushing series is a standardized platform, making this a direct fit for taper-bored split-hub components rated for the Q bushing series. Typical applications include belt-driven blower assemblies, pump drives, and conveyor systems where repeatable shaft mounting and clean removal are required. The 3\/8 x 1-1\/4 inch thread size is used with the bushing's draw-up fasteners during installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType Q split taper design allows draw-up installation and clean removal from taper-bored hubs\u003c\/li\u003e\n\u003cli\u003e1.375 inch bore with 5\/16 inch x 5\/32 inch keyway for positive shaft engagement\u003c\/li\u003e\n\u003cli\u003eMaximum torque rating of 348 inch-pounds\u003c\/li\u003e\n\u003cli\u003eIron construction for durability in industrial and mechanical environments\u003c\/li\u003e\n\u003cli\u003e4.125 inch outside diameter fits standard Q1 series split taper components\u003c\/li\u003e\n\u003cli\u003e3\/8 x 1-1\/4 inch thread size for draw-up fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with split taper sprockets and sheaves accepting a Type Q series bushing with a 1.375 inch bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a qualified mechanical or HVAC technician. De-energize all equipment and lock out the drive system before beginning work. Insert the bushing into the taper-bored hub, align the keyway, and draw up the bushing using the provided thread holes with the appropriate fasteners — do not hammer the bushing into place. Consult the equipment manufacturer's documentation and applicable ANSI standards for proper assembly sequence and fastener engagement.\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 Diameter\u003c\/strong\u003e: 1.375 inches\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: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway Depth\u003c\/strong\u003e: 5\/32 inches\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: 3.92 pounds\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: 1078930\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51540200227122,"sku":"1078930","price":82.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9b5fff87ca14c4f1b7616ad5eb35ee8.jpg?v=1785848728","url":"https:\/\/voomisupply.com\/products\/browning-1078930-type-q-split-taper-bushing-1-375-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
