This is a Ball Bearing that is sealed on both sides. This is a genuine Porter Cable replacement part that is sold individually. • Ball bearings minimize friction between 2 parts in your tool that would otherwise spin and rub against each other. The balls or rollers take the load and spin, distributing the weight evenly while the minimal contact area of the balls reduce friction. This reduces wear on the tool and allows 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.
