A ball bearing is a common type of rolling-element bearing. It will use balls to keep space between the bearing races and eliminate friction and contact between moving parts. Ball bearings used in lawn and garden equipment ensure that axial loads and radial loads are evenly supported and that there is only a limited amount of rotational friction on the component. It distributes weight evenly, but will undergo constant wear and tear from vibration, heat, and friction and will need replacement regularly. This ball bearing is a genuine OEM part suited to use in Craftsman, Cub Cadet, Ryobi, Troy-Bilt, MTD, Huskee, Yard Machines, Bolens, Mastercut, and Yard-Man equipment. It may be needed for repair work done on a lawnmower, snowblower, tiller, edger, or a log splitter.
