Cast from iron for durability and dimensional stability, this sheave features a 0.875 inch bore diameter and a 3.75 inch outer diameter. The finished bore is ready for direct shaft installation without additional machining. With a belt pitch diameter of 3.9 inches and an overall length through bore of approximately 1-5\/32 inches, this sheave is suited for light-to-medium duty fan and blower drive applications. It is typically installed by HVAC technicians and millwrights in belt-driven blower and fan assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave is used in residential and light commercial HVAC systems, particularly in air handling units, furnace blowers, and ventilation fan assemblies that use standard A-section or 4L V-belts. It is also compatible with 3L-section belts where the pitch diameter requirements are met. The single groove configuration makes it appropriate for single-belt drive setups where a straightforward power transfer from motor to blower shaft is needed. Confirm shaft diameter and belt section before installation to ensure proper fit and alignment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore of 0.875 inches — ready for shaft installation without additional machining\u003c\/li\u003e\n  \u003cli\u003e3.75 inch outer diameter with a belt pitch diameter of 3.9 inches for A-section and 4L V-belts\u003c\/li\u003e\n  \u003cli\u003eCompatible pitch diameter for 3L-section belts: 3.16 inches\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for rigidity and wear resistance in continuous-duty applications\u003c\/li\u003e\n  \u003cli\u003eSingle groove design suits single V-belt drive configurations on fans and blowers\u003c\/li\u003e\n  \u003cli\u003eOverall length through bore of approximately 1-5\/32 inches for compact drive arrangements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or aftermarket sheave for single V-belt drive systems using A-section, 4L, or 3L belts in residential and commercial HVAC blower and fan assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by HVAC technicians or millwrights. Disconnect and lock out electrical power to the unit before removing or installing any sheave or belt component. Verify shaft diameter matches the 0.875 inch finished bore and use a properly rated set screw or bushing to secure the sheave to the shaft. Check belt tension and sheave alignment with a straightedge after installation to prevent premature belt or bearing wear.\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 Sheave\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter\u003c\/strong\u003e: 3.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (4L or A Belt)\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (3L Belt)\u003c\/strong\u003e: 3.16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Through Bore\u003c\/strong\u003e: 1-5\/32 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: 1.55 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: 1026376\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51544168137010,"sku":"1026376","price":93.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c80eea08b1ed18d79f4831fa1189e495.jpg?v=1785925110","url":"https:\/\/voomisupply.com\/products\/browning-1026376-single-groove-sheave-0-875in-bore-3-75in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
