Cast from iron for durability and dimensional stability, this sheave features a 7\/8 inch finished bore, a 2.95 inch outer diameter, and a 2.6 inch belt pitch diameter. The groove width is 13\/16 inch, and the overall length through bore is 1-1\/16 inches. It is a standard catalog component used by HVAC technicians, millwrights, and mechanical contractors when replacing or building belt-drive assemblies on fans, blowers, and small motor-driven equipment.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for light-duty to medium-duty belt-drive applications including residential and commercial HVAC blower assemblies, exhaust fans, and motor-to-blower drive systems. The finished bore is ready for direct shaft installation without additional machining, making it a drop-in replacement in systems using 4L or A-section V-belts with a 2.2 inch pitch diameter requirement. It is sized for smaller shaft diameters common in fractional horsepower motor applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle groove design accepts 4L or A-section V-belts\u003c\/li\u003e\n  \u003cli\u003e2.95 inch outer diameter with 2.6 inch belt pitch diameter\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch finished bore — no additional machining required\u003c\/li\u003e\n  \u003cli\u003e13\/16 inch groove width for standard V-belt profiles\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eOverall length through bore of 1-1\/16 inches for compact drive configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement sheave for belt-drive assemblies using 4L or A-section V-belts on fractional horsepower motors and blower shafts with a 7\/8 inch shaft diameter.\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 the existing sheave or belt. Ensure the shaft is clean and free of burrs before sliding the sheave onto the 7\/8 inch bore, and align the sheave face to the mating pulley within accepted tolerances before tensioning the belt. Follow applicable machinery safety standards when setting final belt tension.\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: 2.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 7\/8 inch (finished bore)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter\u003c\/strong\u003e: 2.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter for 4L or A Belt\u003c\/strong\u003e: 2.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 13\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Through Bore\u003c\/strong\u003e: 1-1\/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: 0.75 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: 1027986\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542952476978,"sku":"1027986","price":93.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72afafe7abf0bbc3320027d2d84cd79f.jpg?v=1785911996","url":"https:\/\/voomisupply.com\/products\/browning-1027986-single-groove-sheave-2-95-in-od-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
