Milwaukee Ball Bearing
Model Number: 02-04-0011
The Milwaukee 02-04-0011 is a genuine OEM Ball Bearing for use in compatible Milwaukee tools. A ball bearing is a precision component that supports a rotating shaft or spindle within the tool's motor and drivetrain, using a ring of hardened steel balls running between an inner and outer race to reduce friction and allow smooth, efficient rotation under load. It absorbs both radial and axial forces generated during operation while keeping the shaft aligned in its housing. A worn, corroded, or damaged bearing that produces noise, vibration, heat, or shaft play should be replaced to restore smooth running and to protect the shaft, gears, and housing it supports. Using a genuine Milwaukee OEM bearing ensures the correct inner diameter, outer diameter, width, ball complement, and load rating for the shaft and housing it serves, and because Milwaukee uses distinct part numbers to differentiate bearings with different seal, shield, or clearance configurations even when dimensions look similar, always order by the exact part number from your tool's service parts diagram.
This bearing is identified as the Ball Bearing, Figure 6, on the Milwaukee service parts lists for the M18 FUEL 1-1/2 in. magnetic drill, bulletins 54-46-0420 and 54-46-0421, serving the 2787-20 and 2788-20 and their kit and variant versions. Note that this drill uses several different bearings at different positions in the diagram, so match this one to its Figure 6 position and order by its exact part number rather than by appearance. The shaft, retaining rings, and surrounding drive components are separate items and should be inspected during the repair. Because Milwaukee specifies service parts by serial number as well as catalog number, verify your catalog and serial number against the official Milwaukee service parts diagram before ordering, since running production changes can alter part compatibility within the same catalog number.
