The sheave features a 5\/8 inch finished bore diameter and a 3.45 inch outer diameter, with a groove width of 21\/32 inches. Cast iron construction provides durable wear resistance under continuous belt loading. This sheave is installed by HVAC technicians, millwrights, and mechanical contractors on blower drives, fan assemblies, and belt-driven equipment where precise pitch alignment is required for efficient power transfer.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial HVAC fan and blower drive applications, as well as general industrial belt drive setups. It accepts Type 3L, 4L, and A profile V-belts, making it a versatile fit for common single-belt drive configurations. The finished bore is ready for direct shaft installation at the stated 5\/8 inch diameter, eliminating the need for additional machining before mounting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 5\/8 inch — no machining required for direct shaft installation\u003c\/li\u003e\n  \u003cli\u003eSingle groove design accepts Type 3L, 4L, and A profile V-belts\u003c\/li\u003e\n  \u003cli\u003e3.45 inch outer diameter with 21\/32 inch groove width\u003c\/li\u003e\n  \u003cli\u003eBelt pitch diameter for Type 4L or A belt: 3.2 inches\u003c\/li\u003e\n  \u003cli\u003eBelt pitch diameter for Type 3L belt: 2.86 inches\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability under continuous belt load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or aftermarket single groove sheave for residential and light commercial belt drive systems using Type 3L, 4L, or A profile V-belts on 5\/8 inch 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 power to the drive system before removing or installing any sheave or belt. Verify shaft diameter matches the 5\/8 inch finished bore before mounting, and confirm belt profile compatibility before tensioning. Proper belt tension and sheave alignment are critical to belt life and drive efficiency — use a straightedge or laser alignment tool across sheave faces before finalizing installation.\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3.45 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\u003eBelt Pitch Diameter (Type 4L or A)\u003c\/strong\u003e: 3.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (Type 3L)\u003c\/strong\u003e: 2.86 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\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.3 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: 1026293\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51543197155634,"sku":"1026293","price":73.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f5e65a7e73ec989b9bf1773cd44d54b.jpg?v=1785916669","url":"https:\/\/voomisupply.com\/products\/browning-1026293-single-groove-sheave-5-8-bore-3-45-od","provider":"Voomi Supply","version":"1.0","type":"link"}
