The second evolutionary step adds a flange to the outer shell of the bearing, eliminating the need for a separate hub. The flange cup contains integral raceways, and some of the units include ABS sensors as well. The brake and wheel mount directly to the flange, greatly simplifying installation. Like Gen I, these units are pre-lubricated with an integral lifetime seal. They require no adjustment, are maintenance free, self contained and preloaded to assure long life.
