The Lennox 47W78 V-Belt is a BX-section drive belt with a 61-inch outside circumference, designed for power transmission between motor and blower pulleys. It features a 21/32 inch top width and 13/32 inch height profile, allowing stable grip within matched pulley grooves and the consistent torque transfer under operating load. The BX58 designation identifies its belt size standard for compatibility with specific drive systems. Installed on blower and fan assemblies in HVAC systems, it operates as a mechanical drive component that supports controlled airflow movement and synchronized operation of rotating equipment.
