Description
The York S1-02804807700 Variable Sheave includes a 1-groove design with a 0.875-inch bore and is used to control belt-driven speed adjustments in commercial and industrial HVAC systems. Connected to blower and fan drive assemblies, the sheave transfers motor power to rotating components while allowing speed changes that influence airflow and equipment operations. The adjustable configuration technicians fine-tune system performance to match specific requirements. Positioned on compatible motor shafts and pulley arrangements, the component supports smooth belt movement, proper drive balance, and operation of air handling and ventilation equipment.
