Browning 1002757 Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 1002757 is a two-groove, quick-detachable (QD) bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It accepts a Q1-style QD bushing and accommodates bore diameters from 0.75 inches to 2.6875 inches, making it adaptable to a wide range of shaft sizes. The sheave has a 13.95-inch outside diameter and a Belt Pitch A diameter of 13.2 inches. At 24.35 pounds, this is a substantial cast component suited for medium-to-heavy-duty belt drive configurations. Installation is performed by licensed mechanical contractors or qualified HVAC technicians working on blower and fan drive assemblies.

This sheave is used in belt-driven fan and blower assemblies found in commercial and industrial HVAC systems, air handlers, and process ventilation equipment. The two-groove configuration allows dual V-belt drive setups, which distribute load across both belts and reduce wear on individual drive components. The QD bushing system enables fast removal and reinstallation without damaging the shaft or sheave bore, a practical advantage during scheduled maintenance. The Q1 bushing style fits standard Q1-series QD bushings sold separately.

• Q1-style QD bushing mount for tool-assisted fast installation and removal
• Bore range: 0.75 inches to 2.6875 inches to fit a wide variety of shaft sizes
• 13.95-inch outside diameter with a 13.2-inch Belt Pitch A diameter and 13.6-inch Belt Pitch B diameter
• Heavy-duty construction at 24.35 pounds, suited for sustained commercial and industrial drive loads

Compatibility

Designed for use with Q1-series QD bushings (sold separately) and standard A-section and B-section V-belts. Suitable as an OEM-style replacement or new-installation sheave in commercial fan and blower drive systems requiring a two-groove, large-diameter sheave.

Installation Notes

Installation should be performed by a qualified mechanical technician or licensed HVAC contractor. Disconnect and lock out all power to the drive system before mounting or removing the sheave. The QD bushing must be sourced separately and matched to the shaft diameter before assembly. Inspect belt tension and alignment after installation per the drive manufacturer's guidelines and applicable mechanical codes.
