The first step in hub development consistes of a double row angular contact ball bearing set that provides for lateral as well as vertical loads. These units are pre-lubricated with an integral lifetime seal. They require no adjustment, are maintenance free and self contained. One major benefit of this design is that it required no preloading at installation. While proper preloading could lengthen a bearing’s life, impropely done preloading (due to the difficulty of measuring end play precisely), could just as easily shorten it.
