Milwaukee Rotor/End Cap Assembly
Model Number: 16-01-0400J
The Milwaukee 16-01-0400J is a genuine OEM Rotor/End Cap Assembly for compatible Milwaukee power tools — a complete replacement assembly combining the rotor and end cap components that together form the motor's rotating assembly and bearing retention structure at the end of the motor housing. The rotor is the rotating core of the motor's electromagnetic system — it spins within the stator's magnetic field to produce the rotational output the tool delivers to its drive mechanism. The end cap provides the structural bearing seat and housing closure at the rotor end that maintains the rotor's concentric alignment within the stator and retains the bearing that supports the rotor shaft during rotation. When either the rotor wears, develops electrical faults in its windings, or the end cap cracks or its bearing seat wears, the motor's performance and mechanical integrity are both affected.
Replacing the rotor and end cap as a complete assembly ensures the designed dimensional relationship between the two components for correct bearing alignment and rotor-to-stator clearance. Always verify your specific Milwaukee tool model number and serial number at milwaukeetool.com before ordering rotor/end cap assembly service components, as rotor specifications are unique to each tool model's motor design.
