Browning 1043009 Qd Bushed V-belt Sheave 2 Groove

Product Description

The BROWNING 1043009 is a two-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, refrigeration, and industrial fan or blower systems. It features a 4.45-inch outside diameter and accepts H-style QD bushings with a bore range of 3/8 inch to 1-1/2 inch, giving installers flexibility across a range of shaft sizes. The sheave is compatible with A-profile V-belts, with a belt pitch diameter of 3.7 inches. Weighing 3.1 pounds, it is a compact, durable component suited for belt-drive configurations on air handlers, rooftop units, and exhaust fans. Licensed HVAC technicians and millwrights are the typical installers for this type of drive component.

This sheave is used in residential and commercial belt-drive systems where a two-groove configuration is required to transmit torque from a motor to a blower or fan assembly. The QD bushing mount allows for quick installation and removal without requiring a press, making it practical for field service and scheduled maintenance. The H-style bushing designation narrows the compatible bushing selection and simplifies ordering replacement components. This part suits applications where shaft sizes fall within the 3/8-inch to 1-1/2-inch bore range.

Installation Notes

Installation and removal should be performed by a qualified technician. Disconnect and lock out all power to the drive system before beginning any sheave service. Use the QD bushing hardware sequence specified by the bushing manufacturer to seat and torque the bushing evenly. Verify belt tension and sheave alignment with a straightedge or laser alignment tool after installation to prevent premature belt and bearing wear.
