Description
The York S1-028-13378-000 is a fixed sheave that should only be used in HVAC applications and systems. This is generally of cast iron or steel and it makes certain that electricity is taken right through the system. They are 1″ in bore to ensure that they fit perfectly onto the motor shaft. Combined with a V belt, the sheave controls the motor’s speed and therefore the airflow. It is surprising but true that heating, cooling, and ventilation equipment can be made more efficient by HVAC specialists simply by adjusting the position of the belt on the sheave.
