Manufactured from iron, this sheave accepts B-style QD bushings and accommodates bore diameters from 0.625 inches up to 2.25 inches, making it adaptable to a range of shaft sizes without requiring a dedicated sheave per bore. The outside diameter measures 8.88 inches. Belt pitch diameters are 8.7 inches for 5V cross-section belts, 8.6 inches for B cross-section, and 8.2 inches for A cross-section belts. Licensed HVAC mechanics, millwrights, and mechanical contractors install this sheave in blower, fan, and pump drive assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial HVAC air handler and rooftop unit fan drives, as well as industrial pump and blower applications where 5V, A, or B cross-section V-belts are specified. The three-groove configuration supports multi-belt drives that require higher torque capacity or redundancy compared to single-belt setups. The QD bushing interface allows field installation and removal with standard hand tools, reducing downtime during sheave replacement or belt retensioning service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree grooves compatible with 5V, A, and B cross-section V-belts\u003c\/li\u003e\n  \u003cli\u003eQD bushing mount accepts B-style bushings for tool-friendly installation and removal\u003c\/li\u003e\n  \u003cli\u003eBore diameter range of 0.625 inches to 2.25 inches fits multiple shaft sizes\u003c\/li\u003e\n  \u003cli\u003e8.88 inch outside diameter with belt pitch diameters of 8.7 inches (5V), 8.6 inches (B), and 8.2 inches (A)\u003c\/li\u003e\n  \u003cli\u003eIron construction for durability in continuous-duty drive applications\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging with no minimum order multiplier beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade sheave for belt-drive assemblies using 5V, A, or B cross-section V-belts with B-style QD bushings.

Disconnect and lock out all power to the driven equipment before removing guards or handling sheaves and belts. Use the QD bushing hardware torque sequence specified by the bushing manufacturer to ensure even seating on the shaft. Inspect belt tension and sheave alignment after installation per ANSI\/HVAC drive standards 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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Belt Cross-Sections\u003c\/strong\u003e: 5V, A, B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 8.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (5V)\u003c\/strong\u003e: 8.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B)\u003c\/strong\u003e: 8.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (A)\u003c\/strong\u003e: 8.2 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: Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14.35 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: 3694312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542779593010,"sku":"3694312","price":401.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07b040b6346ff46ea3a0fe0404d57af2.jpg?v=1785907200","url":"https:\/\/voomisupply.com\/products\/browning-3694312-3-groove-qd-v-belt-sheave-8-88-inch-od","provider":"Voomi Supply","version":"1.0","type":"link"}
