Milwaukee Ball Bearing
Model Number: 02-04-1920
The Milwaukee 02-04-1920 is a genuine OEM Ball Bearing for use in compatible Milwaukee tools. Ball bearings are precision components that support rotating shafts and spindles within the tool's motor and drivetrain assemblies — using a ring of hardened steel balls between inner and outer races to reduce friction and allow smooth, efficient rotation under load. They absorb both radial and axial forces generated during operation while maintaining precise shaft alignment within the housing. A worn, corroded, or damaged ball bearing that produces noise, vibration, heat, or shaft play requires replacement to prevent further damage to surrounding components and restore smooth, reliable tool operation.
Using a genuine Milwaukee OEM ball bearing ensures the correct inner diameter, outer diameter, width, ball complement, and load rating for the shaft and housing it serves. Even where dimensions appear similar across part numbers, Milwaukee uses distinct part numbers to differentiate bearings with different seal, shield, or clearance configurations — always use the exact part number from your tool's service parts diagram to ensure the correct bearing is ordered. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct ball bearing for your specific unit.
