Automobile hub bearing is developed on the basis of standard angular contact ball bearing and tapered roller bearing. It integrates two sets of bearings. It has the advantages of good assembly performance, omitting clearance adjustment, light weight, compact structure, large load capacity, pre loading grease for sealed bearing, omitting external hub sealing and avoiding maintenance. It has been widely used in cars, There is also a trend to gradually expand the application in trucks. With the development of technology, car hub unit has been widely used in cars. The application scope and quantity of hub bearing unit 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 used to fix the bearing on the outer raceway, which can simply cover the bearing on the axle and fix it with nuts. Make the maintenance of the car easier. The third generation of hub bearing unit is the combination of bearing unit and anti lock brake system ABS. The hub unit is designed with inner flange and outer flange. The inner flange is fixed on the drive shaft with bolts, and the outer flange installs the whole bearing together.
Inside Diameter 43mm ~ 55mm
