The invention discloses an active self-sensing thrust rolling bearing type senor based on a piezoelectric time reversal technique and a using method thereof. The device comprises a bearing, wherein the bearing comprises a shaft washer, a housing washer, a rolling element and a retainer; the shaft washer is connected with the housing washer through the rolling element and the retainer; a first piezoelectric material is arranged on the shaft washer; a second piezoelectric material is arranged on the housing washer; the first piezoelectric material is communicated with a signal generating device; the second piezoelectric material is communicated with a signal receiving processing device. The sensor has the advantages that the sensor is high in universality, simple in structure, long in service life and low in cost compared with the prior art, and is applicable to monitoring thrust rolling bearing axial force state.
