Milwaukee Hub Assembly
Model Number: 43-78-0155
The Milwaukee 43-78-0155 is a genuine OEM Hub Assembly for use in compatible Milwaukee tools. The hub assembly is the central rotating component that transfers torque from the drivetrain to an attached wheel, disc, drum, or pulley — serving as the interface between the spindle or shaft and the rotating accessory or drive component. Hub assemblies are precision machined to maintain concentricity between the spindle bore and the outer mounting surface, ensuring balanced, vibration-free rotation of the attached component at operating speed. A worn, cracked, or damaged hub assembly that introduces run-out, imbalance, or slippage between the drive shaft and the attached component requires replacement to restore smooth, accurate rotation.
Using a genuine Milwaukee OEM hub assembly ensures the correct bore dimensions, outer profile, and material specification for the drive interface it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct hub assembly for your specific unit.
