Browning 1043082 Qd Bushed V-belt Sheave 2 Groove

Product Description

The BROWNING 1043082 is a two-groove, QD (Quick Detach) bushed V-belt sheave designed for industrial and HVAC drive systems. It accepts an H-style QD bushing and accommodates bore diameters from 3/8 inch up to 1-1/2 inches, giving installers flexibility across a range of shaft sizes. The outside diameter measures 6.45 inches, with a Belt Pitch A diameter of 5.7 inches and a Belt Pitch B diameter of 6.1 inches. This sheave is a common component in belt-driven fan and blower assemblies, where precise pulley sizing directly affects motor load and airflow output. HVAC mechanics, millwrights, and industrial technicians are the primary installers.

This sheave is suited for use in belt-drive applications including air handling units, commercial blowers, and industrial fan systems that rely on A-section or B-section V-belts. The QD bushing mount simplifies installation and removal without the need for a press, making it practical for field service and equipment rooms with limited access. Its two-groove configuration supports dual-belt drive setups, which distribute load and reduce belt wear in high-cycle applications.

Installation Notes

Installation and removal should be performed by a qualified millwright or HVAC technician. Disconnect and lock out all power to the drive system before removing or mounting the sheave. Ensure the mating shaft is clean and within the specified bore diameter range before seating the QD bushing. Verify belt tension and sheave alignment with a straightedge after installation to prevent premature belt and bearing wear.
