Abstract
A bearing residual life prediction method, a bearing residual life diagnostic apparatus and a bearing diagnostic system can be provided. The bearing diagnostic systemincludes: an eddy current testerthat measures the impedance X of a certain portion of a bearingbefore and after the use of the bearing; a bearing information transmitterthat transmits bearing information scontaining the impedance X; and a bearing information receiverthat receives the information; a diagnostic sectionthat obtains the residual life information sof the bearingbased on the received impedance X; and a life information transmitterthat transmits the residual life information s; and a life information receiverthat receives the information. Hence, the bearing used by the user can be inspected nondestructively, and the residual life of the bearing can be predicted.
