Detailed explanation of hub bearings

2025,10,28

Hub Bearings, also known as hub bearings, are important components that connect the wheels and axles. They are mainly used to support the rotation of the wheels and withstand the weight of the vehicle and various forces generated during driving.

Here is a detailed introduction about it:

Structure and Principle

Wheel hub bearings are usually composed of inner rings, outer rings, rolling elements, and retainers. Its working principle is to achieve smooth rotation of the wheel by rolling the rolling elements between the inner and outer rings, while transferring the load of the wheel to the axle.

Type and Characteristics

Traditional wheel hub bearings: generally use two sets of single row bearings, with a long distance between the effective load centers, inconvenient to apply pre tension, complex installation process, and the need to fill with lubricating grease.

The first generation Wheel Hub Bearing unit: Compared with traditional models, it is simple and reliable to apply pre tension, easy to install, does not require gaskets and lubricating grease supply, has a compact structure, and is equipped with high-performance sealing rings.

The second generation wheel Hub Bearing unit: Based on the first generation, applying pre tension is simpler, more reliable, easy to install, and does not require pressing the steering knuckle. If the outer ring rotates, a sensor rotor can also be installed.

Third generation wheel hub bearing unit: capable of applying optimal pre tension, easy installation, high rigidity, and easy installation of anti lock braking system (ABS) sensors.

Application field

Wheel hub bearings are widely used in various types of motor vehicles such as automobiles and motorcycles. In the automotive industry, whether it is a sedan, light truck, or heavy truck, the support of wheel hub bearings is indispensable. In addition, wheel hub bearings also play a key role in some industrial and special vehicles.
