Browning 1042605 Qd Bushed V-belt Sheave 1 Groove 9.25in

Product Description

The BROWNING 1042605 is a single-groove, QD bushed V-belt sheave designed for industrial and commercial drive applications. It accepts an H-style quick-detach bushing and accommodates bore diameters from 0.375 inches to 1.5 inches, making it adaptable to a wide range of shaft sizes without requiring separate machining. The outside diameter measures 9.25 inches, with an A-profile belt pitch diameter of 8.5 inches and a B-profile belt pitch diameter of 8.9 inches. HVAC technicians, millwrights, and mechanical contractors install this type of sheave on fan and blower assemblies, pump drives, and general power transmission systems where belt-driven equipment requires reliable torque transfer.

This sheave is suited for single-belt drive configurations in both light commercial and industrial settings. Typical applications include air handling unit fan shafts, cooling tower drives, and pump systems where an H-bushing QD style is specified. The QD bushing design allows for quick installation and removal, reducing downtime during scheduled maintenance or drive realignment. Units requiring an A or B cross-section V-belt with a 9.25-inch OD sheave are common candidates for this component.

Key Features

• QD H-style bushing mount allows tool-assisted install and removal without shaft damage
• Outside diameter of 9.25 inches with A-profile pitch diameter of 8.5 inches
• B-profile belt pitch diameter of 8.9 inches for compatibility with B-section belts
• Bore range of 0.375 inches to 1.5 inches accommodates varied shaft sizes
• Weighs 5 pounds for straightforward single-technician handling

Compatibility

Designed for use with H-style QD bushings and A or B cross-section V-belts. Accepts bore diameters from 0.375 inches to 1.5 inches. Specific equipment compatibility depends on the driven shaft diameter and the drive configuration specified by the OEM or system designer.

Installation Notes

Installation should be performed by a qualified millwright, HVAC technician, or mechanical contractor familiar with belt-drive systems. De-energize and lock out the drive system completely before removing or installing any sheave. Mount the H-style QD bushing to the shaft first, then seat the sheave and torque the bushing capscrews evenly in a cross pattern to the bushing manufacturer specifications. After installation, check belt tension and sheave alignment with a straightedge or laser alignment tool before returning the drive to service.
