Abstract: Automobile wheel hub comprising a bearing with rolling elements in a housing in said hub and a device for sensing information, the coding element of which moves integrally with the hub and rotates in front of a stationary sensor, characterized in that the coding element is integrated into the bearing seal and that the sensing element, integral with a support which is stationary with respect to the wheel, is coaxial to the coding element in a radial position essentially equal to the value of the radius of the coding element and longitudinally shifted by a maximum value corresponding to the air gap allowed by the technology of the sensor.
