It is also called a rim, steel ring, wheel, or tire bell. There are many types of wheel hubs depending on the diameter, width, molding method, and material. In the past, most car wheel hub bearings were used in pairs of single-row tapered roller or ball bearings. With the development of technology, car wheel hub units have been widely used in cars. The scope and usage of wheel hub bearing units are increasing, and they have developed to the third generation: the first generation was composed of double-row angular contact bearings.
