Bearings play a crucial role in automotive power systems and are widely used in core components such as engine crankshafts, gearbox gear sets, turbochargers, generators, and starters. The crankshaft main bearing and connecting rod bearing must withstand extremely high explosive pressure and alternating loads, while the gearbox bearing must meet precision shifting and fatigue resistance requirements. The turbocharger bearing must work stably in high-temperature and high-speed environments, while the motor bearing needs to balance high speed and low energy consumption characteristics. These key parts usually use high-strength sliding bearings, tapered roller bearings, or ceramic hybrid bearings to ensure efficient output, reliability, and durability of the power system, directly affecting the performance and service life of the entire vehicle.

Bearings are widely used in the comfort system of automobiles, including seat adjustment mechanisms, sunroof rails, air conditioning outlet blades, and electric tailgate transmission devices. The seat adjustment bearings need to withstand frequent reciprocating motion and ensure quiet and smooth operation. The sunroof rail bearings require wear resistance and dust prevention to ensure long-term reliability. The air conditioning wind direction adjustment bearings need to achieve precise angle control in a limited space. The electric tailgate hinge bearings must balance high load and weather resistance. These applications usually use self-lubricating plastic bearings, micro ball bearings, or sealed sliding bearings to improve driving comfort and extend system service life.

Bearings are mainly used in automotive steering systems to support key components such as steering columns, steering columns, universal joints, and electric power assist motors. The steering column bearings need to have high rigidity and precise rotation control to ensure steering wheel sensitivity and road feedback, while the universal joint bearings need to withstand multi angle torque and maintain smooth power transmission. The motor bearings of electric power steering (EPS) systems must meet the requirements of high speed, low noise, and long life. These applications usually use angular contact ball bearings, four point contact bearings, or specially designed sliding bearings to ensure the reliability, safety, and driving comfort of the steering system.

Bearings are widely used in two wheelers (such as bicycles, electric vehicles, motorcycles) for wheel hubs, axles, steering systems, and transmission components. Wheel hub bearings need to withstand radial and axial composite loads and have waterproof and dustproof performance. Axle bearings support pedal power transmission requirements with high rigidity and low friction resistance. Bowl bearings in the steering system directly affect handling flexibility, while internal bearings in motorcycle engines need to withstand high temperature and high-speed environments. These applications often use sealed deep groove ball bearings, angular contact bearings, or tapered roller bearings to ensure smooth riding, safety, and long-term durability.
