Bearing-ball 104-8699

This is a Genuine OEM replacement part used on a variety of Lawn Mowers. This item is made out of Metal and it is Sold Individually. If either the ball bearing or the bearing retainer wear out this will cause the wheels have trouble turning. 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. 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.
