Bearing 386780-00

This needle bearing is open on one side and closed on the other. This genuine DeWalt replacement part is sold individually. • Ball bearings minimize friction between rotating parts in your tool. The balls or rollers bear the load and spin, distributing the weight evenly, while the minimal contact area of the balls reduces friction. This reduces wear on the tool, allowing it to run smoothly. • Bearings experience constant wear when the tool is in operation from pressure, heat, vibration and friction. Because of this, many Bearings need periodic maintenance or replacement.
