Milwaukee Rotor/Back Cap Assembly
Model Number: 16-01-2831
The Milwaukee 16-01-2831 is a genuine OEM Rotor/Back Cap Assembly for use in compatible Milwaukee tools. This combined assembly integrates the brushless motor's permanent magnet rotor and the rear end cap into a single factory-assembled unit — ensuring the rotor shaft, rear bearing bore, and end cap are precision-aligned relative to each other before installation. The rear end cap houses the rotor's rear bearing, provides the structural rear support for the motor stack, and may incorporate cooling air inlet ports or fan mounting features. Providing the rotor and back cap together ensures correct concentricity between the rotor's shaft and the rear bearing bore, eliminating the risk of misalignment that can cause vibration or premature bearing wear.
Using a genuine Milwaukee OEM rotor/back cap assembly ensures the correct rotor geometry, bearing bore concentricity, and end cap dimensions for the brushless motor it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct assembly for your specific unit.
