Development Course Of Hub Bearing
- Mar 01, 2018 -

The car's hub bearings used to be in pairs using single row tapered rollers or ball bearings. With the development of technology, cars have been widely used in car hub units. The use and usage of hub bearing units are increasing, and have now been developed to the third generation:

The first generation is made up of double row angular contact bearings.

The second generation Outer Raceway has a flange for fixing the bearing, which can be simply fixed on the axle with a nut. Make the maintenance of the car easy.

The third generation hub bearing unit is a combination of the bearing unit and ABS of the anti-lock braking system. The hub unit is designed with Nefaran and external flanges, the Nefaran is bolted to the drive shaft, and the outer flange is fitted with the entire bearing.

Fourth generation hub bearing

The fourth generation hub bearing unit is the constant speed universal joint and bearing as a whole, to solve the existing technology due to the hub and the constant speed universal joint structure makes the size of the hub to increase the weight of the shortcomings. The fourth generation hub bearing unit has been successfully developed and is believed to be widely used in all kinds of automobiles in the near future. These unit products are characterized by: do not need to adjust the bearing assembly clearance, bearing assembly process more reasonable, reduce the weight of the volume reduction, disposable grease can almost permanent use, reduce the overall production costs, more conducive to large-scale popularization.
