Built from cast iron, this sheave accepts 5V, A, and B cross-section V-belts and features an outside diameter of 15.68 inches with a belt pitch diameter of 15.5 inches for 5V-profile belts. The B-style QD bushing mount allows bore diameters ranging from 5\/8 inch to 2-1\/4 inches, making it adaptable to a wide range of shaft sizes. Licensed tradesmen and mechanical contractors use this sheave in belt-driven fan, blower, and pump assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and commercial HVAC belt-drive blower assemblies, industrial fan drives, and pump systems where a single 5V, A, or B section V-belt is required. The QD bushing system simplifies installation and removal on shafts within the supported bore range, reducing downtime during maintenance or drive ratio changes. It is a common component in air handling units, centrifugal fans, and motor-to-shaft power transfer setups where a large-diameter sheave is needed to achieve the correct speed ratio.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-groove design for 5V, A, and B cross-section V-belts\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 15.68 inches; belt pitch diameter of 15.5 inches (5V profile)\u003c\/li\u003e\n  \u003cli\u003eBore range from 5\/8 inch to 2-1\/4 inches via B-style QD bushing\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability in high-cycle drive applications\u003c\/li\u003e\n  \u003cli\u003eQuick-Detachable bushing mount for fast shaft installation and removal\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 31171804 for procurement and catalog classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation sheave for belt-drive systems requiring a single-groove 5V, A, or B section V-belt with a B-style QD bushing and a shaft diameter between 5\/8 inch and 2-1\/4 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanical or HVAC technician. De-energize and lock out the drive motor before mounting or removing the sheave. The QD bushing must be matched and torqued to the bushing manufacturer specifications; do not over-tighten or use impact tools on bushing fasteners. Verify belt tension and sheave 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: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Belt Sections\u003c\/strong\u003e: 5V, A, B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 15.68 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (5V)\u003c\/strong\u003e: 15.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (A)\u003c\/strong\u003e: 15.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B)\u003c\/strong\u003e: 15.4 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\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 18.8 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: 3693819\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51541917794610,"sku":"3693819","price":386.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2465998d98fe1a5ef4daae15ad17b47.jpg?v=1785887763","url":"https:\/\/voomisupply.com\/products\/browning-3693819-qd-bushed-v-belt-sheave-1-groove-15-68-in","provider":"Voomi Supply","version":"1.0","type":"link"}
