Cast from iron for durability, this sheave features a 0.75 inch bore diameter and an 11.4 inch belt pitch diameter, making it suited for standard B-section and A-section V-belts. The hub length through bore measures 1-15\/32 inches. Licensed HVAC technicians, millwrights, and mechanical contractors install this type of component when replacing or building belt-driven blower, fan, or pump assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave fits single-groove V-belt drive configurations commonly found in air handling units, belt-driven blowers, and light industrial machinery. It accommodates belt pitch diameters of 11.0 inches for 4L or A-type belts and 10.66 inches for 3L-type belts. The finished bore is ready to install on a 0.75 inch shaft, and the overall sheave width through bore is 1-15\/32 inches. Typical applications include residential and light commercial HVAC fan drive systems requiring a reliable, fixed-bore cast iron pulley.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle groove design accepts standard A-section, 4L, and 3L V-belts\u003c\/li\u003e\n  \u003cli\u003eFinished 0.75 inch bore fits directly onto 0.75 inch drive shafts without additional machining\u003c\/li\u003e\n  \u003cli\u003e11.4 inch outside diameter with 11.0 inch pitch diameter for A and 4L belt types\u003c\/li\u003e\n  \u003cli\u003eCast iron construction provides strength and wear resistance in continuous-duty drive applications\u003c\/li\u003e\n  \u003cli\u003eHub length through bore of 1-15\/32 inches for secure 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-driven fan and blower assemblies requiring a 0.75 inch bore, 11.4 inch OD cast iron pulley compatible with A-section, 4L, and 3L V-belts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or qualified mechanical contractors. Before servicing belt drive assemblies, de-energize and lock out the equipment per NFPA 70E and local electrical codes. Verify shaft diameter matches the 0.75 inch finished bore before installation. Inspect the mating V-belt for wear and proper tension after installing the sheave, and confirm belt alignment across both sheaves before returning the system to service.\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (A \/ 4L)\u003c\/strong\u003e: 11.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (3L)\u003c\/strong\u003e: 10.66 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 11.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Length Through Bore\u003c\/strong\u003e: 1-15\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Finished Bore\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.32 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: 1027515\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51538871812402,"sku":"1027515","price":611.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c8d50c26548e9712eecec46ceab8730.jpg?v=1785828630","url":"https:\/\/voomisupply.com\/products\/browning-1027515-single-groove-sheave-0-75-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
