Abstract
A rotation sensor equipped bearing capable of detecting a highly precise absolute angle with no correction work required after incorporation into a bearing installed equipment. An absolute angle sensor equipped bearing assembly includes a sensor equipped bearing and a correction data storing device. The sensor equipped bearing has a rotation detector capable of providing, as a detection output indicative of the rotation angle of a rotating raceway ring relative to a stationary raceway ring, two analog outputs that are offset 90° in phase relative to each other in terms of electrical degree. The correction data storing device stores a correction data for correcting an error when the absolute angle of the rotation angle of the rotating raceway ring is calculated from the two analog outputs and which is paired with the sensor equipped bearing.
