It features a minimum pitch diameter of 1.72 inches, a maximum diameter of 4.65 inches, and a 5 inch outside diameter, allowing it to continuously vary drive speed by adjusting belt position across the pulley face. The pulley is 3.5 inches long and bored to a 7\/8 inch inside diameter with a 3\/16 x 3\/32 inch keyway for positive shaft engagement. Rated at 0.5 horsepower at 1750 RPM and 0.333 horsepower at 1150 RPM, this component suits light-duty variable speed drive setups. Installation is typically performed by millwrights or mechanical technicians.\u003c\/p\u003e\u003cp\u003eThis variable speed pulley is intended for use in HVAC fan drives, blower assemblies, and other light industrial or commercial mechanical systems where adjustable output speed is required without changing the motor. It accepts B-series V-belts and is suited for applications requiring continuous speed variation within the rated horsepower range. The spring-loaded design automatically maintains belt tension as the pitch diameter changes, reducing the need for manual belt adjustment during operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpring-loaded design automatically maintains belt tension across the variable pitch range\u003c\/li\u003e\n\u003cli\u003eAccepts B-series V-belts for broad belt availability\u003c\/li\u003e\n\u003cli\u003eKeyway included (3\/16 x 3\/32 inches) for positive shaft-to-pulley engagement\u003c\/li\u003e\n\u003cli\u003eRated 0.5 HP at 1750 RPM and 0.333 HP at 1150 RPM for light-duty drive applications\u003c\/li\u003e\n\u003cli\u003eEconoline series construction for standard variable speed drive replacements\u003c\/li\u003e\n\u003cli\u003e3.5 inch length with 7\/8 inch bore accommodates common shaft sizes in fan and blower assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for spring loaded variable speed pulleys used in residential and light commercial belt-drive fan and blower applications accepting B-series V-belts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the drive system before beginning work. Verify shaft diameter and keyway dimensions before mounting. Do not exceed the rated horsepower at the specified RPM, and ensure proper belt alignment after installation to prevent premature wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Econoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Pitch Diameter\u003c\/strong\u003e: 1.72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 4.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Bore)\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway\u003c\/strong\u003e: With Keyway, 3\/16 x 3\/32 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: 0.5 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower at 1150 RPM\u003c\/strong\u003e: 0.333 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 68514427095\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51540768850226,"sku":"68514427095","price":848.18,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2aebc8f13b1a2c02bbb6834ae6ea3af7.jpg?v=1785863752","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514427095-variable-speed-pulley-5in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
