Browning 3694114 Qd Bushed V-belt Sheave 2 Groove

Product Description

The BROWNING 3694114 is a 2-groove, QD bushed V-belt sheave designed for industrial and commercial HVAC drive systems. It accepts standard V-belts and 5V cross-section belts, with a belt pitch A diameter of 18.0 inches, a belt pitch B diameter of 18.4 inches, and a belt pitch 5V diameter of 18.5 inches. The outside diameter measures 18.68 inches. The QD (Quick Detachable) bushing system allows fast installation and removal without special tooling. Bore diameter ranges from 5/8 inch minimum to 2-1/4 inch maximum, accommodating a wide range of shaft sizes. Installed by HVAC mechanics and industrial maintenance technicians on fan and blower drive trains.

This sheave is suited for fan coil units, air handling units, centrifugal blowers, and similar belt-driven equipment found in commercial and light industrial HVAC applications. The 2-groove configuration allows use with dual V-belt drives, which distributes load and increases drive reliability on higher-torque applications. It is compatible with B-style QD bushings, which are selected separately based on shaft diameter. This part weighs 33.5 pounds, making proper lifting and rigging standard practice during installation.

Installation Notes

Installation should be performed by a qualified HVAC mechanic or industrial maintenance technician. Disconnect and lock out power to the drive system before removing any existing sheave or belts. The QD bushing must be ordered separately and matched to the shaft diameter within the 5/8 inch to 2-1/4 inch range. After mounting, check belt tension and sheave alignment with a straightedge before returning the unit to service.
