This high-performance blower pulley (sheave) is a critical component for maintaining the efficiency of belt-driven HVAC systems. Designed for heavy-duty use in commercial air handlers and rooftop ventilation units, this 5.95-inch diameter pulley ensures precise power transmission from the motor to the blower fan. If your system is experiencing belt slippage, excessive vibration, or reduced airflow, replacing a worn or grooved sheave is essential to restore peak performance and prevent premature belt wear. Featuring a 1 3/8-inch bore, this precision-machined part is engineered for durability and consistent rotation in high-demand climate control environments. It is an ideal replacement for technicians and facility managers looking to maintain reliable airflow in large-scale air conditioning and heating equipment.
