With an outer diameter of 6.55 inches and a bore size of 1.125 inches, this pulley is built to transmit power between a motor shaft and a blower wheel or fan assembly. Variable pitch pulleys allow technicians to adjust belt speed and airflow without replacing the pulley, making them a practical choice for balancing and commissioning air distribution systems. Licensed HVAC technicians and sheet metal mechanics are the typical installers for this type of component.\u003c\/p\u003e\n\u003cp\u003eThis pulley fits standard single-groove V-belt drive configurations commonly found in residential and light commercial air handlers, furnace blower assemblies, and belt-drive fan coil units. The 6.55-inch OD and 1.125-inch bore suit a range of blower motor shaft sizes used across these system types. It ships in a box quantity of one unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6.55-inch outer diameter for compatibility with standard V-belt drive setups\u003c\/li\u003e\n  \u003cli\u003e1.125-inch bore accommodates common blower motor shaft sizes\u003c\/li\u003e\n  \u003cli\u003eSingle-groove design matches one-belt drive configurations\u003c\/li\u003e\n  \u003cli\u003eVariable pitch construction allows field adjustment of drive speed and airflow\u003c\/li\u003e\n  \u003cli\u003eSold individually, one unit per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for single-groove V-belt pulley applications in residential and light commercial HVAC blower and fan drive assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDisconnect and lock out electrical power to the air handler or furnace before servicing the blower drive assembly. A licensed HVAC technician should verify proper belt tension and pulley alignment after installation using standard alignment tools. Confirm that the motor shaft diameter matches the 1.125-inch bore before installation. Follow applicable local mechanical codes when servicing belt-drive systems.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 6.55 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Grooves\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Quantity\u003c\/strong\u003e: 1\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: LAU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: g078101848\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LAU","offers":[{"title":"Default Title","offer_id":51467395203378,"sku":"G078101848","price":183.6,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946031.png?v=1783903428","url":"https:\/\/voomisupply.com\/products\/lau-g078101848-variable-pitch-pulley-6-55-in-single-groove","provider":"Voomi Supply","version":"1.0","type":"link"}
