Browning 3693702 Qd Bushed V-belt Sheave 1 Groove

Product Description

The BROWNING 3693702 is a single-groove, Quick Detachable (QD) bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. Built from iron, this sheave accepts B-style QD bushings and accommodates bore diameters ranging from 5/8 inch to 2-1/4 inches, providing installation flexibility across a wide range of shaft sizes. The 6.88-inch outside diameter and 6.7-inch belt pitch diameter for 5V belt cross-sections make it a practical drop-in choice for blower drives, fan assemblies, and other belt-driven equipment maintained by HVAC technicians and millwrights.

This sheave is suited for residential and light commercial HVAC systems as well as general industrial machinery requiring a single-groove V-belt drive. Typical installations include supply and exhaust fan assemblies, air handling unit blower drives, and pump drives where reliable belt power transmission is required. The QD bushing design simplifies both installation and removal compared to fixed-bore sheaves, reducing service time on equipment.

Installation Notes

Installation should be performed by a qualified HVAC technician or millwright. Disconnect and lock out all electrical power to the drive system before beginning work. The QD bushing must be properly seated and fasteners torqued per the bushing manufacturer's instructions before returning the drive to service. Inspect belt tension and alignment after installation to prevent premature wear.
