It features a 6.28-inch outside diameter and accepts bore sizes ranging from 5\/8 inch to 2-1\/4 inch, accommodating a wide range of shaft sizes through its quick-detachable bushing system. The sheave is compatible with A, B, and 5V belt profiles, with pitch diameters of 5.6 inches for A belts, 6.0 inches for B belts, and 6.1 inches for 5V belts. HVAC technicians and mechanical contractors install this component on blower assemblies, fan drives, and pump drives where reliable belt-driven torque transfer is required.\u003c\/p\u003e\n\u003cp\u003eThis sheave fits residential and light commercial belt-drive systems where three-groove configurations are used to balance load distribution and reduce belt wear. The QD bushing style simplifies field installation and removal without requiring complete shaft disassembly. It is well suited for air handling unit blower drives, condenser fan assemblies, and similar rotating equipment that uses classical or 5V wedge belt standards. The B-style bushing bore range makes this sheave adaptable to a broad variety of motor and blower shaft sizes encountered in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-groove design distributes load across multiple belts for balanced drive performance\u003c\/li\u003e\n  \u003cli\u003eQD quick-detachable B-style bushing allows fast installation and removal in tight spaces\u003c\/li\u003e\n  \u003cli\u003e6.28-inch outside diameter suits standard blower and fan drive configurations\u003c\/li\u003e\n  \u003cli\u003eCompatible with A, B, and 5V belt profiles for broad application flexibility\u003c\/li\u003e\n  \u003cli\u003eBore range of 5\/8 inch to 2-1\/4 inch accommodates common motor and shaft sizes\u003c\/li\u003e\n  \u003cli\u003eWeighs 9 pounds, typical of cast iron construction used in power transmission sheaves\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade sheave for belt-driven HVAC blower assemblies, fan drives, and pump drive systems using A, B, or 5V profile belts with a B-style QD bushing mount.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or mechanical contractor. Disconnect and lock out all electrical power to the unit before handling any rotating drive components. The QD bushing must be seated and torqued to the sheave hub using appropriate fasteners before belt tensioning; do not operate the drive with loose bushing hardware. Verify belt alignment with a straightedge or laser alignment tool after installation to prevent premature belt and bearing wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Grooves\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch A Diameter\u003c\/strong\u003e: 5.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch B Diameter\u003c\/strong\u003e: 6.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch 5V Diameter\u003c\/strong\u003e: 6.1 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: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Style\u003c\/strong\u003e: B (QD Quick-Detachable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171804\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: 3694239\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542754197810,"sku":"3694239","price":285.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/799e77d4d18cef995c171e0ab9466d9f.jpg?v=1785906320","url":"https:\/\/voomisupply.com\/products\/browning-3694239-qd-bushed-v-belt-sheave-3-groove","provider":"Voomi Supply","version":"1.0","type":"link"}
