Aerator Bearing 539000317

This is a genuine OEM bearing which is designed for use with lawn and garden equipment and is sold individually. Made of high-quality metal and measuring at a 1-inch inner-diameter, this bearing will likely need to be replaced often because it is a high-wear part. This bearing is used to distribute weight evenly using small inner balls within the bearing itself, and the locking collar fastens the bearing onto the shaft to reduce movement from motor vibrations. If you are unsure of how many bearings your equipment will need, make sure to check any available diagrams.
