Machined from cast iron, this sheave features a 0.875 inch finished bore diameter and a 3.75 inch outer diameter. The pitch diameter is 3.0 inches for 4L or A-style belts, and the overall length through the bore is 1-5\/32 inches. Cast iron construction provides the dimensional stability and wear resistance expected in continuous-duty belt drive applications. Installation requires no additional boring or finishing, making it a direct-fit replacement in standard V-belt drive setups.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for single-groove V-belt drives in residential and light commercial HVAC systems, blower assemblies, fan drives, and general power transmission equipment. It is compatible with 4L and A-series V-belts. HVAC technicians and mechanical contractors commonly use this type of sheave when replacing or re-sizing drive components on air handling units, belt-drive fans, and motor-to-blower assemblies. The finished bore eliminates field machining, reducing installation time on service calls and new installations alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 0.875 inches — no additional machining required\u003c\/li\u003e\n  \u003cli\u003eSingle groove design accepts 4L or A-series V-belts\u003c\/li\u003e\n  \u003cli\u003e3.0 inch pitch diameter for accurate belt speed and drive ratio calculations\u003c\/li\u003e\n  \u003cli\u003e3.75 inch outer diameter with 1-5\/32 inch length through bore\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for dimensional stability and long service life in continuous-duty applications\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 V-belt drive systems using 4L or A-series belts with a 0.875 inch bore shaft.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or mechanical contractor. De-energize and lock out all power to the equipment before removing or installing any drive components. Verify shaft diameter and keyway dimensions before seating the sheave, and ensure belt tension and alignment are set per the equipment manufacturer specifications after installation. Refer to applicable mechanical and electrical codes for safe work practices on belt drive systems.\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: 0.875 inches (finished)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (4L \/ A Belt)\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength 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\u003eBelt Type Compatibility\u003c\/strong\u003e: 4L or A-series V-belt\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: 1028166\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51541712503090,"sku":"1028166","price":133.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29caa5f6ddb744b346157b8b43fb2b80_3a102cdc-4007-402e-8502-4bd7073682e9.jpg?v=1785882750","url":"https:\/\/voomisupply.com\/products\/browning-1028166-single-groove-sheave-0-875-in-bore-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
