It features a 5\/8-inch bore diameter and a 3.95-inch outside diameter, with a belt pitch diameter of 3.2 inches and an overall bore length of 1-5\/32 inches. The groove width measures 7\/8 inches. Cast iron construction provides durability and dimensional stability under continuous rotational loads. This sheave is installed by HVAC technicians, millwrights, and mechanical contractors on fan, blower, and motor shaft assemblies where a finished bore eliminates the need for additional machining.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial belt-drive applications including air handlers, furnace blowers, exhaust fans, and similar equipment driven by A-belt or 4L-belt configurations. The finished bore is pre-sized at 5\/8 inches and is ready for direct shaft installation without modification. It is a common replacement component when a worn or damaged single-groove sheave needs to be swapped on an existing drive system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 5\/8 inches — no machining required for direct shaft fit\u003c\/li\u003e\n  \u003cli\u003eSingle groove design compatible with A-section and 4L-section V-belts\u003c\/li\u003e\n  \u003cli\u003e3.2-inch belt pitch diameter for accurate drive ratio calculations\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch groove width matches standard A and 4L belt profiles\u003c\/li\u003e\n  \u003cli\u003eOverall bore length of 1-5\/32 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 single groove sheave for belt-drive systems using A-section or 4L-section V-belts with a 5\/8-inch shaft diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician. Disconnect and lock out all power to the drive system before removing or installing the sheave. A hub puller may be required to remove the existing sheave from the shaft. Verify shaft diameter and belt section compatibility before installation, and align sheave grooves within manufacturer tolerances to prevent premature belt wear.\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\u003eBore Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (A \/ 4L)\u003c\/strong\u003e: 3.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Through Bore\u003c\/strong\u003e: 1-5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Belt Sections\u003c\/strong\u003e: A, 4L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.8 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: 1028208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51540130955570,"sku":"1028208","price":96.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfeae79b96814582282b930ce3cd8d37.jpg?v=1785846551","url":"https:\/\/voomisupply.com\/products\/browning-1028208-single-groove-sheave-5-8-bore-3-95-od","provider":"Voomi Supply","version":"1.0","type":"link"}
