With an outside diameter of 6.88 inches and a bore range of 5\/8 inch to 2-1\/4 inches, this sheave accommodates a wide range of shaft sizes through its B-style QD bushing. It is compatible with A, B, and 5V cross-section belts, with pitch diameters of 6.2 inches, 6.6 inches, and 6.7 inches respectively. HVAC technicians, millwrights, and mechanical contractors install this type of component in fan and blower drive assemblies where precise speed ratios and reliable torque transfer are required.\u003c\/p\u003e\u003cp\u003eThis sheave suits belt-drive applications in commercial and industrial HVAC air handlers, blower units, and auxiliary drive systems. The two-groove configuration allows for parallel belt arrangements that distribute load and provide redundancy. The QD bushing system enables fast installation and removal without special tooling, making it well suited for equipment where periodic sheave changes or belt replacements are routine maintenance tasks. The bore range of 5\/8 inch to 2-1\/4 inches gives installers flexibility across a variety of motor and shaft configurations commonly found in mechanical systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-groove design distributes belt load across parallel drive belts\u003c\/li\u003e\n\u003cli\u003eB-style QD bushing system allows quick installation and removal without special tooling\u003c\/li\u003e\n\u003cli\u003eBore range of 5\/8 inch to 2-1\/4 inch fits a wide variety of motor and driven-shaft sizes\u003c\/li\u003e\n\u003cli\u003eCompatible with A, B, and 5V cross-section V-belts\u003c\/li\u003e\n\u003cli\u003e6.88 inch outside diameter supports common fan and blower drive ratios\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or upgrade sheave for two-groove V-belt drive systems using A, B, or 5V cross-section belts with a B-style QD bushing.

Disconnect and lock out all power to the drive system before beginning any sheave work. Seat the QD bushing fully before torquing fasteners, and verify belt tension and sheave alignment with a straightedge or laser alignment tool after installation. Always inspect the mating bushing bore and shaft for wear or damage before reassembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Grooves\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6.88 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\u003eBelt Pitch A Diameter\u003c\/strong\u003e: 6.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch B Diameter\u003c\/strong\u003e: 6.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch 5V Diameter\u003c\/strong\u003e: 6.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Style\u003c\/strong\u003e: B (QD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.95 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171804\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: 3693983\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542334669106,"sku":"3693983","price":178.96,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea25151db0273ad9d085c2658b99db9f_fe5eff86-6175-4293-af62-ea910940ed0a.jpg?v=1785898505","url":"https:\/\/voomisupply.com\/products\/browning-3693983-qd-bushed-v-belt-sheave-2-groove","provider":"Voomi Supply","version":"1.0","type":"link"}
