As vehicles continue to evolve toward full connectivity, electrification, and autonomous operation, traditional mechanical components are being transformed into intelligent, data-driven systems. One of the most significant advancements in this shift is the development of smart wheel hubs and sensor-integrated wheel bearings.
Once simple elements that supported wheel rotation, wheel bearings are now becoming sophisticated monitoring devices capable of enhancing safety, performance, and predictive maintenance. This transformation is redefining how modern vehicles operate and interact with their environment — especially in connected and autonomous mobility.
What Makes a Wheel Bearing “Smart”?
A smart wheel bearing integrates electronic sensors directly into the bearing or hub assembly. These sensors collect real-time data that can be transmitted to the vehicle’s control units, allowing continuous monitoring and precise adjustments.
Key integrated technologies include:
-
Speed sensors (ABS/ESP)
-
Temperature sensors
-
Load and vibration sensors
-
Wireless communication modules
-
Diagnostic microchips
These technologies enable the bearing to not only rotate the wheel smoothly but also become a reliable source of critical information for vehicle safety and performance systems.
