It accepts a B-style QD bushing and accommodates bore diameters from 5\/8 inch up to 2-1\/4 inch, giving installers flexibility when matching shaft sizes in the field. The outside diameter measures 7.28 inches, with a 5V belt pitch diameter of 7.1 inches and a B-section pitch diameter of 7.0 inches. At 14.8 pounds, this is a heavy-duty cast sheave suited for continuous-duty belt drive systems. HVAC mechanics and millwrights install this sheave to transfer power from motors to fan wheels, blowers, and similar rotating equipment.\u003c\/p\u003e\n\u003cp\u003eThis sheave is used in commercial and industrial mechanical systems where V belt drives power air handling units, rooftop units, exhaust fans, centrifugal blowers, and similar rotating equipment. The four-groove configuration allows multiple belt runs in parallel, distributing load across the drive and reducing belt wear. The QD bushing system simplifies installation and removal on motor or shaft ends without requiring special pullers. This part is installed by HVAC technicians, millwrights, and mechanical contractors working on belt drive assemblies in both new construction and replacement service scenarios.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFour-groove design supports parallel multi-belt drive configurations for high-load applications\u003c\/li\u003e\n  \u003cli\u003eQD bushed mount with B-style bushing for tool-accessible installation and removal\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 7.28 inches with 5V pitch diameter of 7.1 inches\u003c\/li\u003e\n  \u003cli\u003eWide bore range from 5\/8 inch to 2-1\/4 inch accommodates a variety of shaft sizes\u003c\/li\u003e\n  \u003cli\u003eCompatible with both A-section and B-section V belts as well as 5V cross-section belts based on pitch diameter specs\u003c\/li\u003e\n  \u003cli\u003eRobust construction at 14.8 pounds for continuous-duty belt drive service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install sheave for four-groove V belt drive assemblies using B-style QD bushings.

Disconnect and lock out all power to the motor and drive assembly before beginning work. Confirm the correct B-style QD bushing is on hand before mounting, as the bushing is ordered separately from the sheave. Follow the bushing manufacturer torque sequence when tightening set screws, and inspect belt tension and sheave alignment with a straightedge 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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 7.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch 5V Diameter\u003c\/strong\u003e: 7.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch B Diameter\u003c\/strong\u003e: 7.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch A Diameter\u003c\/strong\u003e: 6.6 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)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14.8 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: 3694569\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542059778354,"sku":"3694569","price":308.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfde66162c5231b1a3cba7147ab2f928.jpg?v=1785890840","url":"https:\/\/voomisupply.com\/products\/browning-3694569-qd-bushed-v-belt-sheave-4-groove","provider":"Voomi Supply","version":"1.0","type":"link"}
