This ball bearing assembly has a wide variety of uses in a number of gasoline-powered yard tools. Bearings are used to provide smooth, friction-free motion between the rotating parts of equipment where pieces fit together and move. The weight and momentum of the rotating motion are distributed to the ball bearings, which prevents wear on the equipment and allows smooth, repetitive motion. Ball bearings are used in equipment such as tillers and lawn tractors, as well as other power equipment that is self-propelled. The bearings will wear out over time since they are on the receiving end of all the angular momentum of the equipment being used. One of the chief locations where bearing assemblies need to be replaced are the drive wheels of the riding mowers and lawn tractors. The bearings are located in brass housings specifically machined to hold them. Since it can be difficult to remove the old ball bearing assemblies from these housings, it is worth considering simply replacing the entire housing as well as the bearing. These bearings are genuine OEM manufactured replacement parts. They are compatible with MTD, Yard-Man, Troy-Bilt, Husky, Cub Cadet, and Yard Machine lawn tools.
