Milwaukee Ball Bearing 2-Shield 12.7x32x10 mm
Model Number: 02-04-1850
The Milwaukee 02-04-1850 is a genuine OEM 2-Shield Ball Bearing with dimensions of 12.7x32x10 mm — referring to a 12.7 mm inner diameter, 32 mm outer diameter, and 10 mm width — for use in compatible Milwaukee tools. The 2-shield configuration means the bearing features metal shields on both sides of the ball complement. Unlike rubber seals, metal shields do not contact the inner race, resulting in lower friction than a sealed bearing while still providing protection against larger debris and particles entering the ball complement during operation. Ball bearings 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. A worn, corroded, or damaged 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 2-shield ball bearing ensures the correct 12.7x32x10 mm dimensional specification, shield type, 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.
