Ball Bearing 02-04-0915

This authentic replacement part is designed for use with Milwaukee sawzalls. Ball bearings are used to reduce friction between rotating parts. The balls or rollers take the load and spin, distributing the weight evenly while the minimal contact area of the ball reduces friction. Bearings experience constant wear from pressure, heat, vibration and friction, because of this, many bearings need to be periodically replaced. Please note this high-quality component is sold individually. Make sure to refer to the appropriate diagrams of your model for the correct location and application of this part.
