It accepts A, B, and 5V cross-section belts and accommodates bore diameters from 5\/8 inch up to 2-1\/4 inch, making it adaptable to a range of shaft sizes. The outside diameter measures 5.28 inches, with a belt pitch diameter of 5.1 inches for 5V belts, 5.0 inches for B-section belts, and 4.6 inches for A-section belts. Weighing 5.9 pounds, this sheave uses a B-style QD bushing for secure, precise mounting on drive shafts. Licensed HVAC and mechanical technicians install this type of component when replacing or rebuilding blower and fan drive assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for belt-drive applications in commercial rooftop units, air handling units, industrial fans, and other equipment that relies on V-belt power transmission. The QD bushing design allows the sheave to be mounted and removed without specialty bearing pullers, reducing labor time during scheduled maintenance or drive replacement. It is particularly common in HVAC blower assemblies where variable pitch or fixed-pitch drives require a reliable, field-replaceable sheave with a wide bore range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree grooves accept A, B, and 5V cross-section V-belts\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 5.28 inches with 5.1-inch 5V belt pitch diameter\u003c\/li\u003e\n  \u003cli\u003eBore range from 5\/8 inch to 2-1\/4 inch accommodates multiple shaft sizes\u003c\/li\u003e\n  \u003cli\u003eB-style Quick Detachable bushing for tool-accessible installation and removal\u003c\/li\u003e\n  \u003cli\u003eWeighs 5.9 pounds — suitable for standard fan and blower drive shaft loads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement sheave for commercial and industrial V-belt drive systems requiring a three-groove QD bushed pulley with a 5.28-inch outside diameter.

Disconnect and lock out all electrical power to the drive unit before removing existing sheave components. The QD bushing must be properly seated and fastened according to standard torque procedures for the bushing size before returning the drive to service. Inspect belt tension and alignment after installation to prevent premature belt or 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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (5V)\u003c\/strong\u003e: 5.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B)\u003c\/strong\u003e: 5.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (A)\u003c\/strong\u003e: 4.6 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 (Quick Detachable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.9 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: 3694189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51539106300210,"sku":"3694189","price":167.08,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea25151db0273ad9d085c2658b99db9f_f68d4a29-e413-450f-ba56-27021fed0e86.jpg?v=1785834767","url":"https:\/\/voomisupply.com\/products\/browning-3694189-3-groove-qd-v-belt-sheave-5-28-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
