As a critical basic component in the automotive industry, bearings are deeply integrated into the five core systems of a vehicle and represent the key component that defines overall vehicle reliability and performance limits. They directly underpin driving safety, operational efficiency, service life, and ride comfort, making them indispensable to modern vehicle design and manufacturing.
In the powertrain system, plain bearings and rolling bearings are deployed in crankshafts, connecting rods, turbochargers, and other high-load components. These bearings are engineered to withstand extreme operating conditions including high temperatures, high rotational speeds, and repeated impact loads, ensuring stable and consistent power output.
The transmission system relies on tapered roller bearings, angular contact ball bearings, and other specialized bearing structures for gearboxes, differentials, and clutches. These components support efficient torque transmission and smooth gear shifting, while maintaining dimensional stability and fatigue resistance under continuous heavy-duty operation.
The chassis and running gear center on wheel bearing units, which work in tandem with suspension and shock absorber bearings. Together, they balance combined radial and axial loads, enhance vehicle handling precision, and extend the service life of the entire running system under diverse road and load conditions.
Steering system bearings are optimized to reduce steering resistance and improve steering return accuracy, making them particularly well-suited for electric power steering (EPS) systems. This refinement supports responsive, stable steering performance, a key factor in modern driving safety and user experience.
For new energy vehicles, dedicated bearing solutions—including high-speed motor bearings, insulated bearings, and low-friction bearings—are developed to address harsh operating challenges. These include ultra-high rotational speeds, electrical corrosion, and wide operating temperature ranges, enabling efficient and stable performance of electric drive systems.
High-precision, long-life, lightweight automotive bearings serve as a fundamental enabler for improved fuel economy, reduced NVH (Noise, Vibration and Harshness), and extended vehicle maintenance intervals. They also represent a vital foundational part in advancing the global trends of automotive electrification and intelligence.
