This high-quality fixed single-groove motor pulley is a critical component for belt-driven blower assemblies in residential and commercial HVAC systems. Designed for precision and durability, this pulley attaches directly to the blower motor shaft to provide consistent, reliable power transfer to the fan belt. A properly functioning pulley ensures optimal airflow, reduces vibration, and prevents premature wear on the motor and blower belts. If your furnace or air handler is making squealing noises, vibrating excessively, or experiencing reduced air circulation, a worn or damaged drive pulley may be the cause. This heavy-duty replacement part is engineered to maintain tension and alignment for efficient climate control performance.
Type: Blower Motor Pulley
Size: Standard Drive Pulley
Application: Used primarily in belt-driven furnace blowers, air handlers, and central air conditioning units to facilitate rotation between the drive motor and the blower wheel.
Specifications: Fixed bore design, single groove for standard V-belt compatibility, precision-machined for reduced wobble and noise.
