Double row auto bearing's main function is to bear the load and provide accurate guidance for the rotation of wheel hub. Double row auto bearing bears both axial load and radial load, and is a very important part.The traditional double row auto bearing are composed of two sets of tapered roller bearings or ball bearings. The mounting, oiling, sealing and clearance adjustment of the bearings are carried out on the automobile production line.This structure makes it difficult to assemble in the automobile factory, high cost, poor reliability, and the automobile still needs to be cleaned, oiled and adjusted during maintenance.Double row auto bearing 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.
Double row auto bearing used to be mostly paired with single row tapered roller or ball bearings.With the development of technology, double row auto bearing have been widely used.Double row auto bearing are increasingly used and used in the third generation: the first generation consists of double row angular contact bearings.The second generation outer raceway has a flange used to fix the bearing, which can be simply sheathed the bearing onto the axle and fixed with a nut.Make it easy to maintain the car.The third generation hub bearing unit is a combination of bearing unit and ABS.The hub unit is designed with an inner flange and an outer flange, which is bolted to the drive shaft and the outer flange is installed together with the entire bearing.
