Product Description

The BROWNING 3693769 is a single-groove, quick-detachable (QD) bushed V belt sheave designed for use in belt-driven mechanical systems found in HVAC, industrial fan, pump, and blower applications. Machined from iron, this sheave accepts B-style QD bushings and accommodates bore diameters ranging from 5/8 inch to 2-1/4 inch. The outside diameter measures 9.28 inches, with a belt pitch diameter of 9.1 inches for 5V belts. It is installed by HVAC technicians and mechanical contractors performing drive component replacements or new drive system builds.

This sheave is suited for single-belt drive configurations using 5V, A, or B section V belts. It is a common choice for residential and light commercial HVAC blower assemblies, cooling tower fan drives, and pump drive systems where a QD-style bushing mount is required for easy installation and removal. The B-style bushing bore range allows fitment across a wide variety of shaft sizes encountered in the field.
