The invention discloses a mechanical sealing property testing device. An electric main shaft is connected with a single cantilever working main shaft; floating support of the single cantilever working main shaft is achieved by virtue of the geometric pressure compressing function of a moving ring end surface and a static ring end surface; the edge end of a force measurement sleeve is of a flange structure; an axial force strain piece is arranged on the force measurement sleeve; a shaft sleeve sleeves the single cantilever working main shaft and penetrates through end covers at the left end and right end of a sealing cavity; the shaft sleeve is slidably connected with the single cantilever working main shaft in a sliding manner in the axial direction and in a positioning manner by using an embedding block in the circumferential direction; two sections of threads of which the screw pitches are equal and the spiral lines are in opposite directions are formed in the shaft sleeve; the threads are respectively screwed with a left screw nut and a right screw nut; the back sides of two push rings respectively contact two moving ring bases; the moving ring bases are connected with the shaft sleeve in an sliding manner in the axial direction and in a positioning manner in the circumferential direction; a through hole which is communicated with a sealed end surface is formed inside a static ring; an infrared probe is arranged inside the through hole. Due to the structural design, measurement on property parameters such as large diameter and high rotation speed of mechanical sealing, particularly the measurement on the axial force and the temperature between sealed end surfaces can be achieved.
