Description
The Lennox 49W50 Blower Sheave/Pulley is a mechanical drive component that transfers rotational motion from the motor to the blower assembly, enabling airflow generation. It operates through a belt-driven mechanism, using a single A-groove design with a 5.95-inch outer diameter and 1-inch bore to maintain proper belt alignment and torque transmission within HVAC systems. It connects with the drive belt and motor pulley to support system operation. Its use helps maintain consistent airflow, supports efficient energy transfer, and contributes to stable performance during heating and cooling cycles.
