Browning BK40H CLEAR PK 1-Groove CI Sheave 3.95" OD

The Browning BK40H CLEAR PK Sheave Cast Iron is a belt-driven transfer case for residential and commercial HVAC systems. It is installed in blower, fan, and motor drive units, contributing to the speed control of equipment and the effective transfer of power between various components of the connected airflow systems. The single-groove, 3.95-inch outside diameter, cast iron construction fits with compatible belt drive and pulley applications. The sheave is mounted on a specially-designed motor or shaft assembly, which helps to keep the belt properly aligned, to control its rotation, and to maintain consistent mechanical performance.
