Browning 1042951 Qd Bushed V Belt Sheave 2 Groove 3.35 in

Product Description

The BROWNING 1042951 is a two-groove, QD bushed V belt sheave designed for use with A and B cross-section V belts. It features a 3.35-inch outside diameter and accepts an H-style QD bushing to accommodate bore sizes from 3/8 inch up to 1-1/2 inches. Cast iron construction provides the durability and rigidity required for continuous-duty drive applications. This sheave is installed by HVAC technicians, millwrights, and mechanical contractors working on blower and fan drive assemblies where precise belt alignment and secure shaft mounting are critical.

This sheave is suited for residential and light commercial air handling systems, belt-driven blowers, fans, and general industrial drive applications. The QD bushing design allows the sheave to be mounted and removed without special tools, making it a practical choice for service work where downtime must be minimized. The two-groove configuration supports dual-belt drive setups for added torque capacity and redundancy.

Key Features

• Two grooves compatible with A and B cross-section V belts
• 3.35-inch outside diameter with 2.6-inch belt pitch diameter for A-section belts
• 3.0-inch belt pitch diameter for B-section belts
• H-style QD bushing accepts bore diameters from 3/8 inch to 1-1/2 inches
• Cast iron construction for high-load, continuous-duty service
• Quick-disconnect bushing design simplifies installation and removal

Compatibility

Designed for use with A and B cross-section V belts in QD bushed sheave drive systems using an H-style bushing. Bore capacity ranges from 3/8 inch to 1-1/2 inches to fit a wide range of shaft sizes common in blower and fan drive assemblies.

Installation Notes

Installation and removal should be performed by a qualified technician with the drive system fully de-energized and locked out per OSHA lockout/tagout procedures. Confirm the H-style QD bushing is properly sized for the shaft before assembly, and follow the bushing manufacturer torque sequence for the cap screws. Inspect belt tension and sheave alignment with a straightedge or laser alignment tool after mounting. Never operate the drive with belts removed from all grooves while the sheave is in motion.
