It features a 3.15 inch outer diameter, a 0.5 inch finished bore, and is constructed from cast iron for durable, long-service performance. The groove accepts A-section or 4L-type V-belts with a pitch diameter of 2.4 inches and a B-diameter of 2.8 inches. The bore length through the hub measures 1-1\/16 inches. This sheave is installed by HVAC technicians, millwrights, and mechanical contractors on belt-driven fans, blowers, and motor drive assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial HVAC systems as well as general industrial belt drive applications. It is commonly mounted on motor or blower shafts in forced-air air handlers, rooftop units, and exhaust fan assemblies where a single-groove A or 4L V-belt configuration is specified. The finished bore allows direct shaft mounting without additional machining when the shaft diameter matches the 0.5 inch bore size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished 0.5 inch bore — ready for direct shaft installation with no additional machining required\u003c\/li\u003e\n  \u003cli\u003eSingle groove profile accepts A-section and 4L V-belts\u003c\/li\u003e\n  \u003cli\u003eCast iron construction provides strength and resistance to wear under continuous belt load\u003c\/li\u003e\n  \u003cli\u003e2.4 inch pitch diameter for A\/4L belt type, 2.8 inch B-diameter\u003c\/li\u003e\n  \u003cli\u003eGroove width of 13\/16 inch suits standard A-section belt widths\u003c\/li\u003e\n  \u003cli\u003eCompact 3.15 inch OD fits space-constrained drive configurations\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 blowers, fans, and general industrial drive systems using A-section or 4L V-belts with a 0.5 inch shaft bore.\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 matches the 0.5 inch finished bore before installation, and ensure the sheave is properly aligned with the mating pulley to prevent premature belt wear. Tighten the set screw or bushing fasteners to the fastener manufacturer's specifications using appropriate hand tools.\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: 3.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Finished Bore\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (A\/4L Belt)\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eB-Diameter (Belt Pitch)\u003c\/strong\u003e: 2.8 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: 0.9 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: 1027994\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51543134011698,"sku":"1027994","price":81.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e37c7ee507504af348ae35c4e853f4a3.jpg?v=1785916235","url":"https:\/\/voomisupply.com\/products\/browning-1027994-single-groove-sheave-3-15in-od-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
