Browning 3694585 4 Groove Qd Bushed V Belt Sheave

Product Description

The BROWNING 3694585 is a four-groove, Quick Detachable (QD) bushed V belt sheave designed for industrial belt drive systems. It accepts 5V, A, and B cross-section belts and features an 8.28-inch outside diameter with a belt pitch diameter of 8.1 inches for 5V belts. The bore range spans 0.625 inches to 2.25 inches, accommodating a B-style QD bushing for secure, precise shaft mounting. Cast iron construction provides the rigidity and durability required in demanding HVAC, fan, blower, and pump drive applications. HVAC and mechanical contractors rely on this sheave as a direct replacement or new-installation component in belt-driven equipment.

This sheave is suited for commercial and industrial belt drive systems where multi-groove 5V, A, or B section belts are used. Common applications include air handling unit fan drives, blower assemblies, pump drives, and compressor belt trains. The QD bushing mount style simplifies field installation and removal, making it practical for service technicians who need to swap pulleys on belt-driven HVAC equipment or industrial machinery without specialized tooling beyond standard hand tools.
