Second generation wheel hub bearings
A hub bearing unit composed of double row tapered roller bearings or double row angular contact ball bearings, with high-performance special lubricating grease added inside the bearing, installed as a unit without adjusting the clearance of the bearing unit.

Third generation wheel hub bearing unit
The main structure consists of two double row angular contact ball bearings with flange structures, one of which is connected to the car wheel hub and the other is connected to the suspension. The inner hole is connected to the transmission shaft. The bearing unit is equipped with a synchronous speed plate and high-performance sensors, and is the signal acquisition unit of the car ABS system. It is a high-tech electromechanical integrated product.

Fourth generation wheel hub bearing unit
One of the inner or outer sleeves is an integral component with the transmission shaft, with a more compact structure than the third generation. It is mainly used in cars with ABS systems and is the development trend of wheel hub bearings for mid to high end cars and high-end commercial vehicles.

Classified by specifications and models
single-row tapered roller bearing
It is one of the most commonly used wheel hub bearings, widely used in the front wheels of front wheel drive vehicles. This type of bearing mainly bears radial loads and can also withstand certain axial loads.
single-row tapered roller bearing
It is one of the most commonly used wheel hub bearings, widely used in the front wheels of front wheel drive vehicles. This type of bearing mainly bears radial loads and can also withstand certain axial loads.
double row tapered roller bearing
Usually used for the rear wheels of heavy trucks and large SUVs, as they can withstand larger radial and axial loads, double row tapered roller bearings provide higher performance compared to single row bearings
