G.D. Supply 9306 Shaft Adapter Bushing

The G.D. Supply 9306 shaft adapter bushing is a zinc-plated steel sleeve designed to adapt a 3/8" motor shaft to components with a 1/2" bore. The bushing measures 3/8" I.D. x 1/2" O.D. x 1-1/16" length, making it useful for HVAC motor, blower wheel, fan, and pulley replacement applications where the shaft and bore diameters do not match.

The G.D. Supply 9306 incorporates a 3/16" open keyway slot or round hole for set-screw engagement, helping maintain a proper mechanical connection with compatible components. Its zinc-plated steel construction provides a durable interface between the motor shaft and driven component.

For field replacement, verify the motor shaft diameter, blower wheel or pulley bore, keyway arrangement, and available shaft length before installation.
