The sheave features a 5\/8 inch finished bore, a 3-3\/4 inch outer diameter, and a belt pitch diameter of 3.0 inches for Type 4L or A belts. Cast iron construction provides durability and dimensional stability under continuous service. The overall length through the bore measures 1-5\/32 inches, and the sheave width is 7\/8 inch. This component is installed by HVAC technicians, millwrights, and mechanical contractors during blower and fan drive assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for single-groove V-belt drive setups in residential and light commercial HVAC air handlers, blowers, and fan assemblies. It accepts standard Type 4L or A V-belts and is appropriate for applications requiring a compact, finished bore pulley without additional machining. The finished bore is ready to install directly onto a 5\/8 inch shaft, making field replacement straightforward in time-sensitive service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 5\/8 inch — no additional machining required for standard shaft fitment\u003c\/li\u003e\n  \u003cli\u003e3.0 inch pitch diameter matched to Type 4L or A V-belts\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for resistance to wear and deformation under belt load\u003c\/li\u003e\n  \u003cli\u003eSingle groove configuration for straightforward single-belt drive setups\u003c\/li\u003e\n  \u003cli\u003eCompact 7\/8 inch width suits space-constrained blower and fan assemblies\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 31171804 for procurement and catalog matching\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 residential and light commercial blower and fan drive systems using Type 4L or A V-belts with a 5\/8 inch shaft bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or millwright. Disconnect and lock out power to the unit before removing or installing any drive components. Verify shaft diameter matches the 5\/8 inch finished bore before mounting, and ensure the replacement sheave is aligned with the mating sheave using a straightedge or laser alignment tool to prevent premature belt wear. Inspect the V-belt for wear and replace if necessary when servicing the sheave.\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: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (Type 4L or A)\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B)\u003c\/strong\u003e: 3.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSheave Width\u003c\/strong\u003e: 7\/8 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: 1.6 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: 1028141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51541427519794,"sku":"1028141","price":111.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de2920fc52917dc448cbca987fe85942.jpg?v=1785875840","url":"https:\/\/voomisupply.com\/products\/browning-1028141-single-groove-sheave-3-3-4-in-od-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
