Milwaukee Ball Bearing 2-Seal 17x40x12 mm
Model Number: 02-04-1745
The Milwaukee 02-04-1745 is a genuine OEM 2-Seal Ball Bearing with dimensions of 17x40x12 mm — referring to a 17 mm inner diameter, 40 mm outer diameter, and 12 mm width — for use in compatible Milwaukee tools. The 2-seal configuration means the bearing features seals on both sides of the ball complement, protecting the internal grease and rolling elements from dust, debris, and moisture contamination during tool 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-seal ball bearing ensures the correct 17x40x12 mm dimensional specification, seal type, ball complement, and load rating for the shaft and housing it serves. Even where dimensions appear identical 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.
