Cylindrical roller bearing the outer flange of the bearing mounted together

Wheel bearings are used in automotive axles for Cylindrical roller bearing and rotating at the hub of providing precise guidance components, both axial load and radial load, is an important part of the car load and rotation. Traditional automotive wheel bearing is composed of two tapered roller bearings or ball bearing combination, bearing installation, oiled, sealed and adjust the clearance is carried out in the car on the production line. Cylindrical roller bearing This structure makes it difficult in a car assembly plant, high cost, poor reliability, and maintenance car maintenance, but also the need for bearing cleaning, oiling and adjustment. Wheel Hub Bearing In standard angular contact ball bearings and tapered roller bearings developed on the basis, it sets bearing as a whole, with good assembly performance can be omitted clearance adjustment, light weight, compact structure, large load capacity, for can advance into the grease sealed bearings, seals and hub maintenance omitted from the outside wheel, etc., have been widely used in cars, and in the truck also has a tendency to gradually expand the application. History Car wheel double row cylindrical roller bearing  are used in pairs over a maximum single row tapered roller or ball bearings. With the development of technology, the car has been widely used car wheel unit. The growing scope and use of hub Cylindrical roller bearing unit has now developed to the third generation: The first generation is a double row angular contact bearing components. The second generation of the outer raceway for Cylindrical roller bearing a fixed flange bearing sleeve may simply be fixed with a nut on the axle. Makes the car maintenance becomes easy. The third generation wheel hub bearing units are using a bearing unit and ABS anti-lock brake system compatible. Wheel hub unit designed to have the inner flange and an outer flange, the flange is bolted to the drive shaft, the outer flange of the bearing mounted together.
