It accepts 5V, A, and B profile belts and features a 6.88-inch outside diameter with a belt pitch diameter of 6.7 inches for 5V belts. The bore range spans 0.625 inches to 2.25 inches, accommodating a B-style QD bushing for secure shaft mounting. Cast iron construction provides the rigidity and wear resistance required for continuous-duty belt drive systems. HVAC equipment mechanics, millwrights, and industrial service technicians install this sheave on fan drives, blower assemblies, and power transmission equipment.\u003c\/p\u003e\u003cp\u003eThis sheave is suited for residential and commercial HVAC air-handling unit fan drives, industrial blower systems, and general-purpose power transmission applications where 5V, A, or B cross-section V-belts are specified. The QD bushing design allows for fast installation and removal without the need for a press, making it practical for field service on rooftop units, large air handlers, and belt-driven industrial equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFour grooves accommodate 5V, A, and B profile V-belts simultaneously or in matched sets\u003c\/li\u003e\n\u003cli\u003eQD bushing mount with B-style bushing for tool-free shaft installation and removal\u003c\/li\u003e\n\u003cli\u003e6.88-inch outside diameter with 6.7-inch belt pitch diameter for 5V cross-section\u003c\/li\u003e\n\u003cli\u003eBore range of 0.625 inches to 2.25 inches for flexible shaft fitment\u003c\/li\u003e\n\u003cli\u003eCast iron construction for durability in continuous-duty drive applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 5V, A, and B cross-section V-belts on systems requiring a B-style QD bushing.

Disconnect and lock out all power to the drive system before handling the sheave or bushing. Ensure the mating shaft is clean and free of burrs before seating the QD bushing. 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\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Grooves\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Belt Profiles\u003c\/strong\u003e: 5V, A, B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (5V)\u003c\/strong\u003e: 6.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (A)\u003c\/strong\u003e: 6.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B)\u003c\/strong\u003e: 6.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 2.25 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: 13.1 pounds\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: 3694544\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51540677787954,"sku":"3694544","price":293.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e1557e5a70f9fb4cf6807cf0a0a6684.jpg?v=1785861675","url":"https:\/\/voomisupply.com\/products\/browning-3694544-4-groove-qd-v-belt-sheave-6-88-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
