Description
The Lennox 32W78 Drive Pulley with Bushing Bore transfers rotational motion within HVAC systems. It features a 4.75-inch outside diameter, single-groove configuration, and a variable bushing bore range from 0.50 to 1.5 inches, allowing compatibility with different motor shaft sizes and belt types. These specifications determine alignment, speed ratio, and torque transfer during operation. Invented on motor shafts and assemblies such as blowers or fans, it operates as a mechanical drive component, enabling efficient power transmission across the system.
