Cast iron construction gives this sheave the rigidity and wear resistance required for continuous operation on belt-driven HVAC, fan, and blower systems. The 2-1\/2 inch outer diameter pairs with a 3\/4 inch finished bore, so no additional machining is required before installation. The groove width of 13\/16 inches accepts standard A or 4L belt cross-sections. Bench-stock replacement for service technicians maintaining belt-drive fan assemblies on air handlers, condensing units, and light commercial equipment.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial belt-drive applications where a single V-belt transfers power from a motor shaft to a blower wheel, fan, or pump. The finished bore is ready to mount directly to a 3\/4 inch shaft. Typical installations include belt-driven blower assemblies in furnaces, air handlers, and evaporative coolers. The compact 2-1\/2 inch OD makes it appropriate for low-speed, high-torque fan drive arrangements where space around the drive is limited. HVAC technicians and millwrights are the primary installers for this type of component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished 3\/4 inch bore — no machining required, mounts directly to standard shaft\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch outer diameter with 1.9 inch pitch diameter for A or 4L belt types\u003c\/li\u003e\n  \u003cli\u003e13\/16 inch groove width fits standard A-section and 4L V-belt cross-sections\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for rigidity and long service life under continuous belt load\u003c\/li\u003e\n  \u003cli\u003eSingle groove design for straightforward single-belt drive arrangements\u003c\/li\u003e\n  \u003cli\u003eOverall bore length of 1-1\/16 inches provides adequate shaft engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement sheave for single-belt drive assemblies using A-section or 4L V-belts on a 3\/4 inch shaft.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or millwright. Disconnect and lock out all electrical power to the drive system before removing or installing any sheave. Verify shaft diameter and belt cross-section match the sheave specifications before mounting. After installation, check belt tension and alignment per standard belt-drive service practices before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSheave Type\u003c\/strong\u003e: Single Groove\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 3\/4 inch (finished)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (A or 4L Belt)\u003c\/strong\u003e: 1.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Through Bore\u003c\/strong\u003e: 1-1\/16 inches\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: 0.55 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: 1027846\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542816915762,"sku":"1027846","price":85.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29caa5f6ddb744b346157b8b43fb2b80_1ed85956-a568-4dd8-b9da-d940e34615cf.jpg?v=1785908217","url":"https:\/\/voomisupply.com\/products\/browning-1027846-single-groove-sheave-2-1-2-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
