Zusammenfassung:	Provided is a calculation method used for a bearing device including a rotating member, a bearing which supports the rotating member so that the rotating member can rotate, a housing which holds the bearing, and sensors which are installed in the housing or a non-rotating part of the bearing to measure a distance to a surface that rotates with the rotating member, where an amount of change in a diameter of the rotating member is calculated based on measurement results by the sensors provided at three or more positions on a plane orthogonal to a rotation axis of the rotating member.
