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 as a whole. It has good assembly performance, can omit clearance adjustment, light weight, compact structure, and load capacity. Large, sealed bearings can be pre-loaded with grease, omit external wheel hub seals, and are free from maintenance. They have been widely used in cars, and there is a trend to gradually expand their applications in trucks.
The main function of the hub bearing is to bear the 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 automobile production plants, high cost, and poor reliability, and the bearings need to be cleaned, oiled and adjusted when the automobile is maintained at the repair point.
In the past, single-row tapered roller or ball bearings were used in pairs for the most common wheel hub bearings for cars. With the development of technology, car hub units have been widely used in cars. The use range and usage of wheel 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 for fixing the bearing on the outer raceway, and the bearing can be simply sleeved on the axle and fixed with a nut. Makes the maintenance of the car easier. The third-generation wheel hub bearing unit uses the bearing unit to cooperate with the anti-lock brake system ABS. The hub unit is designed with an inner flange and an outer flange. The inner flange is bolted to the drive shaft, and the outer flange installs the entire bearing together. Worn or damaged hub bearings or hub units will cause inappropriate and costly failures of your vehicle on the road, and even cause damage to your safety.
The company processes and manufactures various and all kinds of international brand bearings.
