Description
The Lennox Y5539 V-Belt Notched BX60 is a blower drive used to transmit mechanical power between a motor and standard pulleys. It operates through frictional contact within a section of a cogged V-profile, allowing stable torque transfer while maintaining proper belting tension under load. In HVAC systems, it is commonly used in air handlers, furnaces, and packaged units to drive the blower assembly responsible for air circulation. The belt plays a key role in maintaining consistent airflow through heating and cooling cycles supporting overall system performance and mechanical synchronization between rotating components.
