Manufactured from iron, this sheave accepts an H-style QD bushing and accommodates bore diameters from 3\/8 inch up to 1.5 inches, making it adaptable across a wide range of shaft sizes. The outside diameter measures 5.25 inches, with a belt pitch A diameter of 4.5 inches and a belt pitch B diameter of 4.9 inches. It is compatible with both A and B cross-section V-belts. Licensed HVAC mechanics, millwrights, and mechanical contractors typically handle installation of components like this in belt-driven blower and fan assemblies.\u003c\/p\u003e\u003cp\u003eThis sheave is suited for residential and commercial belt-driven systems including supply and return air fan assemblies, cooling tower drives, and other rotating equipment requiring a two-groove V-belt arrangement. The QD bushing design allows the sheave to be installed and removed without specialized tooling, reducing labor time during scheduled maintenance or component replacement. It is well-suited for retrofit and replacement scenarios where the existing drive arrangement calls for an H-bushing style sheave with a 5.25-inch outside diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-groove design accepts A and B cross-section V-belts\u003c\/li\u003e\n\u003cli\u003eQD H-style bushing for tool-free install and removal\u003c\/li\u003e\n\u003cli\u003e5.25-inch outside diameter with 4.5-inch belt pitch A diameter and 4.9-inch belt pitch B diameter\u003c\/li\u003e\n\u003cli\u003eBore range from 0.375 inch to 1.5 inches accommodates multiple shaft sizes\u003c\/li\u003e\n\u003cli\u003eIron construction for durability in continuous-duty drive applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit sheave for belt-driven fan and blower assemblies requiring a 2-groove, H-bushing QD sheave with a 5.25-inch outside diameter and compatibility with A and B cross-section V-belts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or HVAC technician. Disconnect and lock out all power to the drive system before removing or installing any sheave or bushing. Inspect the mating QD H-style bushing and shaft for wear or damage before assembly. Confirm proper belt tension and sheave alignment 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\u003eModel\u003c\/strong\u003e: 2BK55H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Grooves\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Cross-Sections\u003c\/strong\u003e: A, B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch A Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch B Diameter\u003c\/strong\u003e: 4.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Style\u003c\/strong\u003e: H (QD Quick Detach)\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: 4.35 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171804\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: 1043033\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51539490832690,"sku":"1043033","price":185.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a53e6b5f2fd3faf37ecb24052712d21.jpg?v=1785841573","url":"https:\/\/voomisupply.com\/products\/browning-1043033-2bk55h-qd-v-belt-sheave-2-groove-5-25-in","provider":"Voomi Supply","version":"1.0","type":"link"}
