Milwaukee Hub Assembly
Model Number: 43-78-0590
The Milwaukee 43-78-0590 is a genuine OEM Hub Assembly for use in compatible Milwaukee tools. A hub assembly is the central rotating body that connects a shaft to a wheel, gear, disc, or accessory — providing the structural link that transmits rotational force from the drive shaft to the rotating element it mounts. Hubs are used in Milwaukee tool assemblies at sanding pad attachments, blade flanges, belt drive pulleys, and other locations where a rotating accessory or component must be securely mounted to a shaft while transmitting full torque. A worn, cracked, or damaged hub assembly that can no longer maintain a secure, concentric connection between the shaft and the rotating element requires replacement to restore correct, vibration-free rotational drive.
Using a genuine Milwaukee OEM hub assembly ensures the correct bore dimensions, flange geometry, and retention method for the shaft and rotating element it connects. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct hub for your specific unit.
