Browning 3693629 Qd Bushed V Belt Sheave 1 Groove

Product Description

The BROWNING 3693629 is a single-groove, quick-detachable (QD) bushed V belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It accepts B-style QD bushings and accommodates bore diameters ranging from 5/8 inch to 2-1/4 inches, making it adaptable to a range of shaft sizes. The outside diameter measures 5.28 inches, with a belt pitch diameter of 5.1 inches for 5V belts, 5.0 inches for B belts, and 4.6 inches for A belts. Cast from iron, this sheave delivers the durability required in continuous-duty blower and fan drive setups. HVAC technicians and mechanical contractors install this component as part of belt-driven air handler and fan assemblies.

This sheave is suited for residential and light commercial HVAC systems, as well as general industrial drive applications where V belt power transmission is specified. It is commonly installed on supply fan shafts, blower assemblies, and direct-coupled motor drives that use 5V, A, or B section V belts. The QD bushing style allows for straightforward installation and removal without special pullers, which reduces downtime during routine maintenance or belt replacement cycles.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all power to the drive system before removing or installing any sheave or bushing. Ensure the QD bushing is properly seated and fasteners are evenly torqued per the bushing manufacturer's standard procedure. Verify belt tension and sheave alignment after installation to prevent premature belt and bearing wear.
