High load-bearing capacity: need to bear both the vehicle weight (radial load) and the lateral force during cornering and braking (axial load).

Dynamic stability: the design needs to adapt to the shock and vibration under different road conditions, such as bumpy roads or emergency braking.

Low friction coefficient: The use of high-quality materials and precise processing technology makes the friction coefficient between the rolling element and the raceway inside the bearing small, which allows the wheel to rotate smoothly with minimal friction, helping to reduce the vehicle's energy consumption and improve fuel economy.
