A bearing device includes: a rolling bearing having a rotation ring, a fixed ring, and a rolling element; a preload applying member; and a sensor unit. The rotation ring has a rotation ring raceway surface extending in a circumferential direction. The fixed ring has a fixed ring raceway surface extending in the circumferential direction and facing the rotation ring raceway surface with a space therebetween in a radial direction. The rolling element is disposed between the rotation ring raceway surface and the fixed ring raceway surface. The preload applying member applies a preload to the rolling bearing in an axial direction. The sensor unit is detachably attached to one of the fixed ring and the preload applying member, and includes a sensor that detects a state of rotation of the rotation ring.
