Browning 1002393 Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 1002393 is a two-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical systems. Featuring an 8.35-inch outside diameter and a Q1 bushing style, this sheave accommodates bore diameters from 3/4 inch up to 2-11/16 inches, allowing installation on a wide range of shaft sizes without requiring a dedicated bored-to-size unit. At 13.4 pounds, it is built for standard belt-driven blower and fan assemblies. Belt pitch A diameter is 7.6 inches and belt pitch B diameter is 8.0 inches. HVAC technicians and mechanical contractors are the primary installers of this component.

This sheave is suited for residential and light commercial HVAC air handlers, rooftop units, and belt-driven fan systems where a QD bushed, two-groove V-belt drive is specified. The Q1 bushing interface simplifies installation and removal compared to fixed-bore sheaves, making it practical for field service and drive replacements. It is appropriate for systems using standard A or B cross-section V-belts where the pitch diameters align with the 7.6-inch and 8.0-inch specifications provided.

Installation Notes

Installation is typically performed by licensed HVAC technicians or mechanical contractors. Disconnect and lock out all power to the drive system before removing or installing the sheave. The QD bushing should be torqued according to the bushing manufacturer specifications using appropriate hand tools. Verify belt tension and sheave alignment after installation before returning the system to service.
