It features a 0.75 inch finished bore and a 3.95 inch outer diameter, with a cast iron construction that provides durability under continuous load. The bore is finished to size, meaning no additional machining is required before installation. This sheave is suited for use with 4L or A-type belts, with a corresponding pitch diameter of 3.7 inches, as well as 3L-type belts at a pitch diameter of 3.36 inches. HVAC technicians and mechanical contractors install this component on blower assemblies, fan drives, and pump drive systems.\u003c\/p\u003e\n\u003cp\u003eThis sheave is appropriate for single-groove V-belt drive configurations in residential and light commercial equipment. Typical installations include belt-driven blower wheels, condenser fan assemblies, and pump drives where precise pulley sizing is required to maintain target RPM and airflow. The 1.16 inch length through bore ensures adequate belt tracking and shaft engagement in standard shaft configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 0.75 inches — no additional machining required\u003c\/li\u003e\n  \u003cli\u003e3.95 inch outer diameter with 3.7 inch pitch diameter for 4L and A-type belts\u003c\/li\u003e\n  \u003cli\u003eCompatible with 3L-type belts at 3.36 inch pitch diameter\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eSingle groove design for straightforward single-belt drive layouts\u003c\/li\u003e\n  \u003cli\u003e1.16 inch length through bore 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 sheave for single-groove V-belt drive systems using 4L, A-type, or 3L V-belts on 0.75 inch shafts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by HVAC technicians or mechanical contractors. Disconnect and lock out all power to the drive system before removing or installing any sheave or belt. Confirm shaft diameter matches the 0.75 inch finished bore before mounting, and verify belt type and drive alignment after installation. Follow applicable OSHA guarding requirements for exposed belt and pulley assemblies after service is complete.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (4L or A Belt)\u003c\/strong\u003e: 3.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (3L Belt)\u003c\/strong\u003e: 3.36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Through Bore\u003c\/strong\u003e: 1.16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Configuration\u003c\/strong\u003e: Single Groove\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: 1.55 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: 1026426\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51541616787762,"sku":"1026426","price":106.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37198abb2cf15bf69ee99ba959afb904.jpg?v=1785880628","url":"https:\/\/voomisupply.com\/products\/browning-1026426-single-groove-sheave-3-95in-od-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
