Abstract
A rolling bearing device with a sensor includes a rotational component estimator that extracts a rotational synchronization component included in the rotation of an inner shaft relative to an outer ring from each of a signal output by a first displacement detector and a signal output by a second displacement detector. The rotational component estimator performs rotational operation and integration operation.
