Description
The York S1-02809570700 1-Groove Fixed Sheave is a single-groove fixed pulley used in a belt-driven mechanical assembly to transfer rotational motion between shafts. Its 5.75″ outside diameter defines the sheave size, while the 1″ bore provides the shaft mounting interface. The fixed-groove profile maintains a defined belt position during operation rather than providing pitch-diameter adjustment. A belt connects the groove as the connected shaft rotates, transferring torque between the sheave and the driven assembly within HVAC equipment. It forms part of the fan or blower drive arrangement where the specified AK59 sheave configuration is required.
