Cast from iron for durability, this sheave features a 0.625 inch bore diameter and a 9.25 inch outer diameter. The bore comes finished and ready for installation without additional machining. A belt groove depth of 1.469 inches through the bore accommodates standard 4L, A-section, and 3L V-belts. HVAC technicians and mechanical contractors use this sheave to set blower and fan drive ratios on air handling units, package units, and ventilation equipment.\u003c\/p\u003e\u003cp\u003eThis sheave is suited for residential and light commercial HVAC blower assemblies, exhaust fans, and general-purpose belt drive systems where a single groove cast iron pulley is required. The 9.0 inch pitch diameter for 4L and A-type belts and the 8.66 inch pitch diameter for 3L belts allow straightforward drive ratio calculations at installation. Single groove construction keeps the drive simple and compact where multi-belt configurations are not needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFinished bore at 0.625 inches — no machining required before installation\u003c\/li\u003e\n\u003cli\u003eSingle groove design accepts 4L, A-section, and 3L V-belts\u003c\/li\u003e\n\u003cli\u003eCast iron construction for rigidity and wear resistance in continuous-duty drive applications\u003c\/li\u003e\n\u003cli\u003e9.0 inch pitch diameter for 4L and A-type belts; 8.66 inch pitch diameter for 3L belts\u003c\/li\u003e\n\u003cli\u003eOverall length through bore of 1.469 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement single groove V-belt sheave for residential and commercial blower and fan drive assemblies using 4L, A-section, or 3L V-belts with a 0.625 inch shaft.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC technician or mechanical contractor. De-energize and lock out the equipment before removing or installing any drive components. Verify shaft diameter matches the 0.625 inch finished bore before pressing the sheave onto the shaft, and use a proper pulley puller and installation tool rather than striking the sheave directly. Align the sheave face with the mating pulley within manufacturer tolerances and check belt tension after installation per the belt manufacturer guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSheave Type\u003c\/strong\u003e: Single Groove\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 9.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Diameter (4L and A Belt)\u003c\/strong\u003e: 9.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Diameter (3L Belt)\u003c\/strong\u003e: 8.66 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Through Bore\u003c\/strong\u003e: 1.469 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Quantity\u003c\/strong\u003e: 1\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: 4.38 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: 1027325\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51544618828082,"sku":"1027325","price":468.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cdd001c30bdac7cbaaffa08acc382df.jpg?v=1785931660","url":"https:\/\/voomisupply.com\/products\/browning-1027325-single-groove-sheave-9-25-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
