Description
The York S1-02804763700 1-Groove Variable Sheave is an adjustable pulley component used to control the mechanical drive relationship between a motor and driven equipment. Its single-groove design accommodates a belt, while the 0.875″ bore provides the shaft interface. The variable sheave changes the effective pitch diameter of the pulley allowing the belt-drive ratio to be adjusted within the assembly. It works with the motor shaft, belt, and driven pulley to transfer rotational motion through the HVAC equipments. This component is used in belt-driven assemblies where adjustable speed control through the sheave is required.
