Built from cast iron and accepting a Type B QD bushing, this sheave accommodates bore diameters from 5\/8 inch up to 2-1\/4 inches, giving installers flexibility across a range of shaft sizes. The outside diameter measures 8.88 inches, with belt pitch diameters of 8.7 inches for 5V belts, 8.2 inches for A-section belts, and 8.6 inches for B-section belts. At 12.1 pounds, it is a solid, robust component suited for belt-driven blower and fan assemblies. HVAC technicians and mechanical contractors are the primary installers of this sheave.\u003c\/p\u003e\n\u003cp\u003eThis sheave is commonly used in belt-driven fan and blower systems found in commercial and light industrial HVAC equipment, including air handlers, rooftop units, and exhaust fans. The two-groove configuration supports dual-belt drive setups that require torque redundancy or where single-belt loading would be excessive. The QD bushing system simplifies installation and removal without requiring the shaft to be disturbed beyond loosening the bushing hardware, making it practical for scheduled maintenance and belt replacements in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-groove design supports dual 5V, A-section, or B-section V-belt configurations\u003c\/li\u003e\n  \u003cli\u003eQD bushing mount (Type B bushing) allows fast installation and clean removal from the shaft\u003c\/li\u003e\n  \u003cli\u003eBore range of 5\/8 inch to 2-1\/4 inches fits a wide variety of motor and driven-shaft sizes\u003c\/li\u003e\n  \u003cli\u003eCast iron construction provides durability under continuous belt-drive loads\u003c\/li\u003e\n  \u003cli\u003e8.88 inch outside diameter with 8.7 inch 5V pitch diameter for accurate belt speed calculations\u003c\/li\u003e\n  \u003cli\u003eCompatible with 5V, A-section, and B-section V-belt trade sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5V, A-section, and B-section V-belts.

Disconnect and lock out all electrical power to the driven equipment before servicing the drive assembly. The QD bushing should be seated and torqued per the bushing manufacturer's fastener specifications, and belt tension should be set using a belt tension gauge before returning the unit to service. Do not operate with mismatched belt sizes across the two grooves.\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\u003eCompatible Belt Trade Sizes\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 (A-section)\u003c\/strong\u003e: 8.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B-section)\u003c\/strong\u003e: 8.6 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 (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: 12.1 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: 3694031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51541014151474,"sku":"3694031","price":217.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e776f7c807068e9b790fe6e0f89685b.jpg?v=1785867353","url":"https:\/\/voomisupply.com\/products\/browning-3694031-qd-bushed-v-belt-sheave-2-groove-8-88-in","provider":"Voomi Supply","version":"1.0","type":"link"}
