Abstract
A rolling bearing assembly for a wheel includes a cylindrical fixed bearing ring fixed to a vehicle body side, a rotary bearing ring rotatably inserted to inside of the fixed bearing ring, and plural rows of rolling elements rollably arranged between the bearing rings. An annular sensor housing is attached to an inboard side end portion of the fixed bearing ring and includes a plurality of displacement sensors for detecting gaps between the displacement sensors and outer peripheral surfaces of inboard side end portions of the rotary bearing ring in a circumferential direction. Further, an inboard side end portion of the sensor housing is sealed by an inner side seal device.
