Wheel bearing is one of the key parts of the automobile, its main role is to carry the weight and provide guidance for the rotation of the wheel hub, which requires it not only to withstand the axial load but also to withstand the radial load. Traditional automobile wheel bearings are made of two sets of tapered roller bearings or ball bearings, bearing installation, oiling, sealing and clearance adjustment are carried out in the automobile production line. This structure makes it difficult, costly, and unreliable to assemble at the automobile production plant, and the bearings need to be cleaned, oiled, and adjusted when the automobile is maintained at the service point. Wheel bearing unit is in the standard angular contact ball bearings and tapered roller bearings on the basis of the development, it will be two sets of bearings as a whole, with good assembly performance, can be omitted clearance adjustment, light weight, compact structure, large load capacity, for the sealed bearings can be loaded into the grease in advance, omit the external hub seals and maintenance-free, etc., has been widely used in sedans, also in the heavy-duty vehicles to gradually expand the application of the trend.
