Traditional car wheel with bearing is combined by two sets of tapered roller bearings or ball bearings, and the installation of the bearing, oil seal and clearance adjustment is carried out on the auto production line.
This structure makes it difficult to assemble, costly and unreliable in an automobile production plant, and the bearings need to be cleaned, oiled and adjusted when the car is maintained at the maintenance site.
Wheel hub bearing unit is in the standard angular contact ball bearings and tapered roller bearings, on the basis of it will be two sets of bearing as a whole, has the assembly clearance adjustment performance is good, can be omitted, light weight, compact structure, large load capacity, for the sealed bearing prior to loading, ellipsis external wheel grease seal and from maintenance etc, and has been widely used in cars, in a truck also has a tendency to gradually expand the application.
