The invention provides an intelligent debugging device for paired rolling bearings, and the innovation of the invention is that the intelligent debugging device comprises a bracket, a support sleeve,an inner baffle plate, an outer baffle plate, a C-shaped sleeve, a clamping plate, a swinging rod, a pendulum bob, a connection bolt, a tensile pressure sensor, a displacement sensor, a washer and anangle sensor. The beneficial effects of the invention are that the intelligent debugging device is proposed; the device can simultaneously measure a pre-tightening force, a displacement amount and a friction torque, thereby constructing a correlation curve model of the three values; the adjustment of required pre-tightening forces under different working conditions is completed in the adjustment of an actual rolling bearing.
