Hub bearing units must meet the increasingly severe requirements of light weight, energy saving and modularity. In addition, in order to ensure safety and reliability during braking, anti-lock braking systems (ABS) are becoming increasingly popular, so the market demand for sensor-built hub bearing units is also increasing. A hub bearing unit with built-in sensors located between two rows of raceways installs anti-lock braking system (ABS) sensors at a specific clearance section between the two rows of raceways. Its characteristics are: make full use of the bearing internal space, make the structure more compact; The sensor part is sealed to improve the reliability; The sensor of wheel hub bearing for driving wheel is built in. Under large torque load, the sensor can still keep the output signal stable.
