What Type of Bearings are Used in Cars

In the past, the most common use of car hub bearings was single-row tapered roller or ball bearings in pairs. With the development of technology, car hub units have been widely used in cars. The scope and amount of using wheel bearing units are increasing day by day. And it has now 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, which makes the car maintenance much easier.

The third-generation wheel hub bearing unit uses the combination of the bearing unit and 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 make the entire bearing mount together.

The fourth-generation wheel hub bearing unit integrates the constant velocity universal joint and the bearing, which solves the disadvantage of the increased weight due to the the prior art that the size of the wheel hub increases for the integrated structure of the wheel hub and the constant velocity universal joint.

The development of the fourth-generation wheel hub bearing unit has been made huge progress. And we are confident that it will be widely used in various automobiles in the near future. The characteristics of these unit products are: there is no need to adjust the bearing assembly gap. The bearing assembly technology is more reasonable, and the weight is much lighter, the volume is reduced. These unit products can be used almost permanently after the disposable installation, which reduce the overall production cost and is more conducive for the large-scale popularization.
