It features a 3.35 inch outer diameter and a 0.75 inch finished bore, making it a ready-to-install replacement that requires no additional machining. Cast iron construction provides the durability and balance required for continuous-duty belt drive service. The sheave is 0.875 inches wide through the groove and has an overall length through bore of 1.0625 inches. Licensed HVAC technicians and mechanical contractors install this component when replacing worn or damaged sheaves on belt-driven air handlers, condenser fan assemblies, and ventilation equipment.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial belt drive applications where B-section or A-section V-belts are used. The pitch diameter for Type 4L or A belts measures 2.6 inches, and the B-type belt pitch diameter is 3.0 inches. These dimensions make it appropriate for fan and blower shaft assemblies operating at standard motor output speeds. It fits shaft installations where a 0.75 inch bore and standard keyway are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 0.75 inches — no machining required at installation\u003c\/li\u003e\n  \u003cli\u003e3.35 inch outer diameter for standard belt drive sizing\u003c\/li\u003e\n  \u003cli\u003eSingle groove design compatible with A-section and 4L V-belts\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability in continuous-duty applications\u003c\/li\u003e\n  \u003cli\u003e2.6 inch pitch diameter for Type 4L or A belt; 3.0 inch pitch diameter for Type B belt\u003c\/li\u003e\n  \u003cli\u003eOverall length through bore of 1.0625 inches for standard shaft fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement single groove sheave for belt-driven HVAC fans, blowers, and light industrial drive assemblies using A-section or 4L V-belts on 0.75 inch diameter shafts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all electrical power to the equipment before removing or installing any sheave or belt components. Inspect the mating shaft for wear and verify the keyway dimensions before pressing or sliding the sheave into position. Ensure proper belt tension and sheave alignment after installation to prevent premature belt or bearing wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3.35 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Type\u003c\/strong\u003e: Single Groove\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (Type A or 4L)\u003c\/strong\u003e: 2.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (Type B)\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Through Bore\u003c\/strong\u003e: 1.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.875 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: 0.95 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: 1028059\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542799974706,"sku":"1028059","price":103.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29caa5f6ddb744b346157b8b43fb2b80_7bb983e8-be16-41e6-b61e-f596eae7f327.jpg?v=1785907756","url":"https:\/\/voomisupply.com\/products\/browning-1028059-single-groove-sheave-3-35in-od-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
