Description
The York S1-02814720000 Variable Sheave is a mechanical component used to change the drive ratios on variable-speed blower and compressor assemblies in HVAC systems. It is mounted on a 1.125-inch bore shaft and 1-groove and operates with a matching pulley to adjust the speed of the belt-driven motion to allow a fine adjustment of the airflow or compressor output. This sheave will assist in balancing system performance and can adjust proper operating speeds. It helps to ensure the correct mechanical operation of the system and helps to preserve the designed performance of the system in typical heating and cooling conditions.
