The main function of the hub bearing is to bear weight and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component. Traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of the bearings are all carried out on the automobile production line. This structure makes it difficult to 
assemble in the automobile production plant, high in cost, and poor in reliability. Moreover, when the automobile is maintained at the maintenance point, the bearing needs to be cleaned, oiled and adjusted. The hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It combines two sets of bearings into one, with good assembly performance, clearance adjustment can be omitted, light weight, compact structure, and high load capacity. Large, unsealed bearings can be loaded with grease in advance, omit the external hub seal and avoid maintenance, etc., have been widely used in cars, and there is a tendency to gradually expand their application in trucks.
In the past, most car wheel bearings used single-row tapered roller or ball bearings in pairs. With the development of technology, cars have widely used car hub units. The use range and usage of hub bearing units are increasing day by day, and now it has developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, which can simply fit the bearing on the wheel shaft and fix it with nuts. Makes car maintenance easier. The third-generation hub bearing unit uses the combination of the bearing unit and the anti-lock brake system ABS. The hub unit is designed to have an inner flange and an outer flange, the inner flange is bolted to the drive shaft, and the outer flange mounts the entire bearing together. Worn or damaged hub bearings or hub units can lead to inappropriate and costly failures along the way of your vehicle, or even harm to your safety.
