Wheels bearings are the core rotational components in the chassis system that connect the wheels to the axles. The main function is to support the weight of the wheels and provide low friction rotational support for the rotation of the Wheels, while bearing the radial and axial load during the driving of the vehicle to ensure the smooth rotation of wheels.
The structure is usually composed of inner circles, outer circles and rolling bodies (steel balls or rollers) and holding mechanisms. Some integrated rim bearings also contain sensors that monitor the wheel speed and provide a signal to the ABS anti-lock system. The inner circle is supercharged with the axle, the outer circle is connected with the wheel, and the rolling body rolls between the two, converting the sliding friction into rolling friction, which greatly reduces energy consumption.
High quality wheel bearings need to have high load carrying capacity, wear resistance and impact resistance, to adapt to complex road vibration and temperature changes. It directly affects the smoothness and safety of the vehicle and is an indispensable key component in the chassis system.
