As we all know, trucks are assembled from tens of thousands of parts. Whether a model can be strong and durable under long-term use is closely related to the quality and details of the parts. The bearing is one of them. It can be seen in the supporting parts, force-bearing parts, rolling parts and other areas of the truck. Its quality will directly affect the driving quality and vehicle status of the truck.
Bearings are actually components that fix and reduce the load friction coefficient during mechanical transmission. They are mainly used to fix, support and prevent axial rotation. Among them, the components that are highly related to our car experience are axle bearings.
Ball bearings
Among all the bearing parts, the most common is the ball bearing design. Most of these bearings are made of high-chromium steel and are very hard, so it is not easy to grind this material bearing flat. Its structure is composed of balls, inner rings, outer rings and retainers. Why use this design of bearing? Because ball bearings are one of the few bearing structures that can rotate under large loads, and this design also affects the structural application of trucks on bearings at this stage.
The current structure of wheel hub bearings is usually a split two-disc radial thrust roller bearing. Its main function is to bear weight and provide precise guidance for the rotation of the wheel hub. It bears both axial loads and radial loads, and is a very important component. The structure of this bearing is more special than that of needle bearings, sliding bearings, and ball bearings. Under its relatively irregular appearance, it requires a relatively high-quality lubricant with moderate rolling resistance to assist.

However, it is not difficult to understand from the past maintenance records that many trucks have experienced bearing burnout, and there are even cases where bearings have become debris. People can’t help but wonder why such a solid structure would encounter such a problem? Putting aside factors such as long mileage and natural aging of bearings, whether the bearing is easy to damage is actually closely related to the driver’s driving habits and maintenance skills.
