PROBLEM TO BE SOLVED: To provide a sensor-equipped roller bearing device capable of finding moment loads and axial translational loads acting on orbital members with high sensitivity. SOLUTION: A nut 63 is screwed onto an inner shaft 1, and a first spacer 190, a second tubular member 191, and a second spacer 192 are externally fitted and fixed to an outer peripheral surface of the nut 63. The second tubular member 191 is formed by stacking a plurality of silicon steel plates without any gap, and is arranged between the first spacer 190 and the second spacer 192 axially. The outer diameter of an outer peripheral surface of the second tubular member 191 is made larger than the outer diameter of an outer peripheral surface of the first spacer 190 and the outer diameter of the second spacer 192. A detection surface of a first displacement detector 70 is made to radially face a contact portion between the second spacer 192 and the second tubular member 191, while a detection surface of a second displacement detector 71 is made to radially face a contact portion between the first spacer 190 and the second tubular member 191.
