Product Description

The BROWNING 3694064 is a two-groove, QD bushed V-belt sheave designed for use in belt-drive power transmission systems found in HVAC equipment, industrial fans, blowers, and related mechanical applications. The sheave accepts 5V, A, and B belt trade sizes and features an 11.28-inch outside diameter with a belt pitch diameter of 11.1 inches for 5V belts, 10.6 inches for A belts, and 11.0 inches for B belts. It accepts a B-style QD bushing and accommodates bore diameters ranging from 5/8 inch to 2-1/4 inches. At 15.9 pounds, this is a solid cast-iron component built for demanding drive service.

This sheave is commonly installed in rooftop units, air handlers, centrifugal fans, and industrial blowers where two-groove V-belt drive configurations are required. The QD bushing design allows for quick installation and removal without specialized tooling, making it a practical choice for service technicians and mechanical contractors working on both new installations and drive replacements. It is suited for residential and commercial HVAC applications as well as light industrial belt-drive setups.
