Aerator Bearing Flange 539000316

This genuine OEM bearing flange is 4 inches long and 2.5 inches wide. The flange is used to secure bearings (sold separately) to provide support moving parts in aerators, such as the rotating shafts/axles. Each bearing in your aerator requires two flanges each. This protects the parts from friction damage and allows them to spin smoothly. The flange also helps to secure the bearing in place and prevent it from coming loose or falling inside the equipment. You will need to replace your flange bearing if your equipment is making grinding noises during use or if the flange is corroded, or chipped. Each flange is sold individually.
