Browning 3694502 Qd Bushed V-belt Sheave 4 Groove 6.08 in

Product Description

The BROWNING 3694502 is a four-groove, Quick Detachable (QD) bushed V-belt sheave designed for use with 5V, A, and B cross-section belts. It accepts a B-style QD bushing and accommodates bore diameters from 5/8 inch up to 2-1/4 inches, making it adaptable to a wide range of shaft sizes. The outside diameter measures 6.08 inches, with a belt pitch diameter of 5.9 inches for 5V belts. Cast iron construction provides durability in demanding drive applications. HVAC technicians, millwrights, and mechanical contractors install this sheave on blower and fan drive assemblies where precise belt alignment and consistent torque transfer are required.

This sheave is suited for commercial and industrial blower drives, cooling tower fan assemblies, air handling units, and other multi-belt power transmission systems. The four-groove configuration supports multiple belt runs in parallel, allowing higher horsepower transmission without increasing sheave diameter. The QD bushing system simplifies installation and removal, making it a practical choice for equipment that requires periodic maintenance or belt replacement. Compatible belt cross-sections include 5V, A, and B, giving installers flexibility when sourcing replacement belts.

Compatibility

Designed as an OEM-style replacement or new-installation sheave for multi-groove V-belt drive systems using 5V, A, or B cross-section belts with a B-style QD bushing.

Installation Notes

Installation should be performed by a qualified millwright, HVAC technician, or mechanical contractor. De-energize and lock out the drive system before removing or installing the sheave. The QD bushing must be sourced separately and matched to the required shaft diameter. After seating the bushing, verify sheave alignment with a straightedge before tensioning belts to manufacturer specification.
