Built from cast iron and accepting a Type B QD bushing, this sheave accommodates a bore range of 5\/8 inch to 2-1\/4 inches, making it adaptable to a wide variety of shaft sizes. The outside diameter measures 5.48 inches, with a 5V belt pitch diameter of 5.3 inches, an A-section pitch diameter of 4.8 inches, and a B-section pitch diameter of 5.2 inches. At 5.1 pounds, it is a solid, durable component suited for belt-drive systems requiring reliable power transmission across two grooves.\u003c\/p\u003e\n\u003cp\u003eThis sheave is commonly installed on fan and blower drives in commercial HVAC air handling units, rooftop units, and industrial ventilation systems. It is appropriate for use with 5V, A, and B section V-belts. The QD bushing design simplifies installation and removal, which reduces downtime during routine maintenance or belt replacement. HVAC mechanics, millwrights, and industrial maintenance technicians are the primary installers. Matching the correct bushing bore to the driven shaft diameter is essential before finalizing the installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-groove design supports parallel dual-belt drive configurations for balanced load transmission\u003c\/li\u003e\n  \u003cli\u003eCompatible with 5V, A, and B section V-belts for broad application flexibility\u003c\/li\u003e\n  \u003cli\u003eQuick Detachable Type B bushing style allows fast installation and removal without damaging the shaft\u003c\/li\u003e\n  \u003cli\u003eBore range of 5\/8 inch to 2-1\/4 inches fits a wide range of shaft sizes\u003c\/li\u003e\n  \u003cli\u003eCast iron construction provides durability in continuous-duty drive applications\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 5.48 inches suits standard HVAC and industrial fan drive configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit sheave for two-groove V-belt drive systems using 5V, A, or B section belts with a Type B QD bushing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or millwright. Disconnect and lock out all power to the drive system before removing or installing the sheave. Select and install the correct Type B QD bushing to match the driven shaft diameter before mounting the sheave, and torque all bushing fasteners according to the bushing manufacturer specifications. 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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch 5V Diameter\u003c\/strong\u003e: 5.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch A Diameter\u003c\/strong\u003e: 4.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch B Diameter\u003c\/strong\u003e: 5.2 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: Type B QD\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\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.1 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: 3693918\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51544675680562,"sku":"3693918","price":156.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b7770eaf898cc75f63ec168554385d3.jpg?v=1785933211","url":"https:\/\/voomisupply.com\/products\/browning-3693918-qd-bushed-v-belt-sheave-2-groove","provider":"Voomi Supply","version":"1.0","type":"link"}
