Constructed from cast iron, this sheave features a 0.75 inch bore diameter and a 4.45 inch outer diameter. The through-bore length measures 1-5\/32 inches, and the groove is sized to accept standard B, A, 4L, and 3L profile belts. At 1.65 pounds, this is a compact, durable component suited for light-to-medium duty belt drive installations maintained by HVAC technicians and mechanical service professionals.\u003c\/p\u003e\u003cp\u003eThis sheave is typically used in residential and light commercial belt-driven fan and blower assemblies, including supply and return air blower sections in air handling units and furnace systems. It is well suited for retrofit or replacement applications where the original sheave has worn grooves, a damaged bore, or incorrect pitch diameter.

Disconnect and lock out all electrical power to the unit before removing or installing any sheave or belt components. Ensure the shaft and bore are clean and free of burrs before seating the sheave, and verify belt tension and alignment after installation per the equipment manufacturer guidelines. A matched belt and sheave pitch diameter must be confirmed before final assembly to prevent premature wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 4.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough-Bore Length\u003c\/strong\u003e: 1-5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eB Belt Pitch Diameter\u003c\/strong\u003e: 4.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4L or A Belt Pitch Diameter\u003c\/strong\u003e: 4.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3L Belt Pitch Diameter\u003c\/strong\u003e: 3.86 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: 1.65 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171804\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1026541\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51538247254322,"sku":"1026541","price":90.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ced9b57bc225239ae20fa6df96a8e51.jpg?v=1785820722","url":"https:\/\/voomisupply.com\/products\/browning-1026541-single-groove-sheave-4-45-in-od-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
