Description
The Trane SHE05390 Sheave 1VP56 is an essential belt-drive pulley component used to transmit rotational power between a motor and a fan assembly. It mounts on a 7/8-inch shaft, and it works with V-belts to control fan speed by adjusting the effective pitch diameter of the pulley in HVAC equipment. It is commonly installed in air handling units and blower systems and supports airflow regulation through accurate speed matching between drives and driven components. The sheave supports proper belt tracking and stable operation, contributing to consistent air movement in applications.
