Description
The York S1-02804761700 Variable Sheave adjusts belt position to control speed and maintain proper airflow within belt-driven assemblies. With a 1-groove design and a 1.125 inch bore size in HVAC systems, it allows speed variation by changing the effective pulley diameter. It works by altering the position of the movable flange, which adjusts belt alignment and modifies rotational output. Mounted on drive shafts, it interfaces with belt systems to regulate performance. It operates fine-tune airflow, supports system balancing, and improves operational efficiency by allowing controlled speed adjustment.
