Description
The Aaon P66670 Pulley bushing H X 1.38 is a split taper H-type mechanical bushing used in HVAC systems drive assemblies to connect a part hub to a motor or blower shaft. It is designed for use in AAON rooftop units and air handling systems where it locks the sheave securely onto a 1.38″ shaft, maintaining clear alignment under rotational load. It is installed within belt-driven fan systems to support consistent power transfer between motor and pulley, assisting in maintaining airflow through coils and ductwork. Its role in the system is to stabilize the drive assembly and reduce slippage in continuous ventilation and cooling operation.
