It accepts an H-style QD bushing and accommodates bore diameters from 3\/8 inch to 1-1\/2 inches, giving technicians flexibility when matching shaft sizes. The outside diameter measures 4.95 inches, with a belt pitch diameter of 4.2 inches for A-section belts and 4.6 inches for B-section belts. Cast from iron, this sheave is built for the rotational loads common in fan, blower, and pump drive assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial HVAC blower assemblies, cooling tower fan drives, exhaust fan systems, and general industrial V-belt drive setups. Its two-groove configuration allows dual-belt drive arrangements that distribute load and reduce the risk of belt slippage under higher torque conditions. The H-bushing interface is a widely used QD standard, making field installation and removal straightforward during scheduled maintenance or equipment retrofit work. Compatible belt trade sizes are A-section and B-section V-belts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-groove design supports dual A-section or B-section V-belt configurations\u003c\/li\u003e\n  \u003cli\u003eH-style QD bushing interface allows tool-assisted, concentric shaft mounting and clean removal\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 4.95 inches with A-section belt pitch diameter of 4.2 inches\u003c\/li\u003e\n  \u003cli\u003eBore range of 3\/8 inch to 1-1\/2 inches accommodates a wide variety of shaft sizes\u003c\/li\u003e\n  \u003cli\u003eIron construction provides durability in continuous-duty blower and fan drive service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with A-section and B-section V-belts in QD H-bushing sheave drive systems.

Disconnect and lock out all power to the drive system before mounting or removing the sheave. The H-style QD bushing must be sourced separately and torqued evenly in a cross-pattern sequence per the bushing manufacturer specifications. Verify belt tension and sheave alignment with a straightedge or laser alignment tool before returning the drive to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel Number\u003c\/strong\u003e: 2BK52H\u003c\/li\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: 4.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (A-Section)\u003c\/strong\u003e: 4.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B-Section)\u003c\/strong\u003e: 4.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Belt Trade Sizes\u003c\/strong\u003e: A, B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Style\u003c\/strong\u003e: H (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: 3.85 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: 1043025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51543461691698,"sku":"1043025","price":174.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de36766e18b3c643aea872877a9d2298.jpg?v=1785918945","url":"https:\/\/voomisupply.com\/products\/browning-1043025-2bk52h-qd-bushed-v-belt-sheave-2-groove","provider":"Voomi Supply","version":"1.0","type":"link"}
