Browning 1002823 Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 1002823 is a three-groove, quick-detachable (QD) bushed V belt sheave designed for industrial and commercial power transmission applications. Built from cast iron, this sheave accepts A, B, and 5V cross-section belts and features a belt pitch A diameter of 15.0 inches and a belt pitch B diameter of 15.4 inches, with a 15.75-inch outside diameter. The Q1 bushing style allows for straightforward bore sizing across a range from 3/4 inch to 2-11/16 inches, making it adaptable to a variety of shaft configurations. Licensed HVAC mechanics, millwrights, and industrial maintenance technicians are the typical installers of this component in blower and fan drive systems.

This sheave is suited for use in residential and commercial air handling units, industrial fan assemblies, and blower drive systems where multi-groove V belt drives are required. The three-groove configuration allows higher power transmission capacity compared to single-groove designs, distributing load across multiple belts. It is appropriate for new installations and replacement applications on equipment requiring A, B, or 5V belt cross-sections with a QD bushed mount.

Installation Notes

Installation should be performed by a qualified millwright or licensed HVAC technician. Disconnect and lock out all power to the drive system before mounting or removing the sheave. The QD bushing must be properly seated and fasteners tightened evenly in a cross pattern to manufacturer specifications before applying belt tension. Verify belt alignment across all grooves after installation to prevent premature belt and bearing wear.
