Product Description

The BROWNING 3693728 is a single-groove, QD bushed V belt sheave designed for power transmission applications in HVAC, industrial, and mechanical systems. It accepts a quick-detach (QD) style B bushing, allowing fast installation and removal without special tooling. The outside diameter measures 7.28 inches, with a belt pitch diameter of 7.1 inches for 5V belt sections. The bore range spans 5/8 inch to 2-1/4 inch, accommodating a wide variety of shaft sizes. At 7.05 pounds, this cast sheave is a durable, field-proven component used by HVAC technicians and millwrights on blower and fan drive assemblies.

This sheave is suited for single V belt drive configurations in commercial and residential HVAC air handling units, industrial blowers, pumps, and fan systems. The QD bushing system simplifies alignment and re-use during maintenance or drive ratio changes. It is compatible with 5V, A, and B belt sections based on the stated pitch diameters. Installation is performed by licensed HVAC technicians or qualified mechanical contractors wherever belt-driven blower assemblies are serviced or commissioned.
