A sensor equipped wheel support bearing assembly includes rolling elements interposed between double row rolling surfaces defined respectively in outer and inner members in face-to-face relation with each other. One of the inner and outer members, which serves as a stationary member, has an outer diametric surface provided with three or more sensor units. Each of the sensor units includes a strain generating member having two or more contact fixing segments, fixed to the outer diametric surface of the stationary member in contact with therewith, and one or more strain sensors fitted to the strain generating member for detecting a strain occurring in the strain generating member. A load estimating section is provided for estimating a radial load and an axial load in the wheel support bearing assembly, from respective output signals of the sensors.
