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 mi...Read morenimal 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.

Carbon brushes are one of the most commonly replaced power tool parts. This is because carbon brushes are wear items, meaning that through friction and use they will gradually wear away until they need replacing. Worn brushes are a common causes of intermittent motor function, reduced electric braking and reduced motor power. A worn-out brush will often be worn down near to the wire lead and can be cracked, pitted, or burned. When replacing carbon brushes, be sure to inspect your armature for burns, cracks, or other damage which can indicate larger motor problems.
