摘要： A bearing residual life prediction method, a bearing residual life diagnostic apparatus and a bearing diagnostic system can be provided. The bearing diagnostic system 20 includes: an eddy current tester 11 that measures the impedance X of a certain portion of a bearing 24 before and after the use of the bearing; a bearing information transmitter 30 that transmits bearing information s1 containing the impedance X; and a bearing information receiver 31 that receives the information; a diagnostic section 12 that obtains the residual life information s2 of the bearing 24 based on the received impedance X; and a life information transmitter 36 that transmits the residual life information s2; and a life information receiver 40 that receives the information. Hence, the bearing used by the user can be inspected nondestructively, and the residual life of the bearing can be predicted.
