Ball Bearing (607zz) 039140001048

This authentic replacement part is designed for use with Ryobi power tools. 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. Unfortunately, over time parts will wear out and may begin to fail eventually requiring a replacement. Keep in mind this high-quality component is made of durable metal and is sold individually.
