Cast iron construction provides durability and dimensional stability under continuous load. The sheave features a 3.45 inch outer diameter, a 3\/4 inch finished bore, and a groove width of 21\/32 inches. It is compatible with 4L or A-type belts at a 3.2 inch pitch diameter and 3L-type belts at a 2.86 inch pitch diameter. Licensed HVAC technicians, mechanical contractors, and industrial maintenance professionals are the typical installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis sheave is used in belt-driven blower and fan assemblies found in residential and light commercial HVAC systems, as well as general-purpose industrial drive applications. It is suited for installations where a single groove, small-diameter sheave is required on a 3\/4 inch shaft. The finished bore eliminates additional machining at installation. The overall length through the bore measures 15\/16 inches, making it appropriate for compact drive arrangements with limited shaft engagement depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 3\/4 inches — ready to install without additional machining\u003c\/li\u003e\n  \u003cli\u003e3.45 inch outer diameter with a single V-belt groove\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for rigidity and wear resistance under belt tension\u003c\/li\u003e\n  \u003cli\u003eCompatible with 4L or A-type belts at 3.2 inch pitch diameter\u003c\/li\u003e\n  \u003cli\u003eCompatible with 3L-type belts at 2.86 inch pitch diameter\u003c\/li\u003e\n  \u003cli\u003eGroove width of 21\/32 inches suits standard V-belt profiles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit sheave for belt-driven fan and blower assemblies using 3L, 4L, or A-type V-belts on 3\/4 inch diameter shafts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or mechanical maintenance professionals. Disconnect and lock out all power to the drive system before removing or installing any sheave or belt components. Ensure the shaft is clean and free of burrs before seating the finished bore. Align the sheave with the mating pulley using a straightedge or laser alignment tool before tensioning the belt to the manufacturer's specification for the belt type in use.\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: 3.45 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 21\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Through Bore\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (4L or A Belt)\u003c\/strong\u003e: 3.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (3L Belt)\u003c\/strong\u003e: 2.86 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: 0.85 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: 1026319\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51544518852914,"sku":"1026319","price":69.61,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39e6cc49052367aa952fdad133b8759b.jpg?v=1785928682","url":"https:\/\/voomisupply.com\/products\/browning-1026319-single-groove-sheave-3-45in-od-3-4in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
