PROBLEM TO BE SOLVED: To provide a roller bearing device with sensors capable of detecting a load added to a vehicle by simple structure utilizing the components of the roller bearing device. SOLUTION: This roller bearing device with the sensors comprises an outer ring member 4 secured to a suspension apparatus and having a double rows of raceway surfaces on its inner peripheral surface, an inner ring member 6 disposed coaxially with the outer ring member 4 on the inner diameter side of the outer ring member 4 and having double rows of raceway surfaces on its outer peripheral surface, roller elements 7 rollingly interposed between the raceway surfaces of the outer ring member 4 and the inner ring member 6, cages 12 holding the rolling elements 7 at predetermined intervals in the circumferential direction, and the pair of sensors 16, 17 fitted to the outer ring member 4 correspondingly to the cage 12 on each row. The portions of the cages 12 facing the detection surfaces of the sensors 16, 17 are magnetized. COPYRIGHT: (C)2007,JPO&INPIT
