Description
The Lennox 31W50 Blower Pulley is a power transmission part that is used to transmit rotational power of a motor to blower assemblies in HVAC systems. The pulley sustains the belt-driven airflow systems through the maintenance of the correct speed ratio and the torque distribution. It has an 8.28-inch diameter and a 2-inch to 2.438-inch bore on the bushing to suit similar shaft sizes. The profile of machined grooves provides alignment and grip of the belt during rotation. It assists in maintaining constant speed, tracking the belt, and the constant airflow.
