Part of the Econoline Series, this pulley features a 5.65-inch maximum diameter, a 2.69-inch minimum pitch diameter, and an overall length of 4.13 inches. The 1-inch bore is machined with a 1\/4 x 1\/8 inch keyway for positive shaft engagement. Rated at 1 HP at 1750 RPM and 3\/4 HP at 1150 RPM, it suits light industrial and HVAC fan drive applications where variable speed control is required. Licensed HVAC technicians and mechanical contractors are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis pulley is intended for use in systems requiring adjustable-speed belt drives, including residential and light commercial HVAC air handling units, blower assemblies, and general-purpose machinery. It accepts a B-series V-belt and provides variable speed output through its spring loaded sheave design. The Econoline Series is commonly specified in replacement and retrofit scenarios where an OEM-style variable speed drive component is needed. The 6-inch outside diameter and 1-inch inside bore make it compatible with standard shaft configurations in these applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpring loaded variable speed sheave design allows on-the-fly speed adjustment without belt changes\u003c\/li\u003e\n  \u003cli\u003eAccepts B-series V-belt for broad compatibility with standard drive configurations\u003c\/li\u003e\n  \u003cli\u003e1\/4 x 1\/8 inch keyway provides positive, slip-resistant shaft engagement\u003c\/li\u003e\n  \u003cli\u003eRated 1 HP at 1750 RPM and 3\/4 HP at 1150 RPM for reliable light-duty drive performance\u003c\/li\u003e\n  \u003cli\u003eEconoline Series construction balances durability and cost-effectiveness in replacement applications\u003c\/li\u003e\n  \u003cli\u003e1-inch bore fits common shaft sizes found in HVAC blower and fan assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement variable speed pulley for B-series belt drive systems in residential and light commercial HVAC and general mechanical power transmission applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or qualified mechanical contractor. Disconnect and lock out all power to the drive system before removing or installing the pulley. Ensure the shaft and keyway are clean and free of burrs before seating the pulley, and verify belt alignment and tension after installation per the equipment manufacturer guidelines. Refer to applicable mechanical and electrical codes for the installation jurisdiction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Pitch Diameter\u003c\/strong\u003e: 2.69 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 5.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore (Inside Diameter)\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Size\u003c\/strong\u003e: 1\/4 x 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Trade Size\u003c\/strong\u003e: B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 1750 RPM\u003c\/strong\u003e: 1 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 1150 RPM\u003c\/strong\u003e: 3\/4 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Econoline\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.25 pounds\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: LOVEJOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 68514427835\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51542020948274,"sku":"68514427835","price":1037.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bb3051ac01c313b092f59abf43a0d1e.jpg?v=1785889810","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514427835-variable-speed-pulley-1-hp-b-belt","provider":"Voomi Supply","version":"1.0","type":"link"}
