The invention relates to the technical field of bearing testing, in particular to a bearing integrated dynamic performance test device and method. The bearing integrated dynamic performance test device comprises a drive system, a transmission system, a measurement and control system, an environmental simulation system and a mechanical body structure. A motor is adopted by the drive system for driving. The measurement and control system controls the rotation speed of the motor. The transmission system is in a belt transmission mode or a coupler transmission mode. The measurement and control system is provided with a force sensor, a strainmeter, an eddy current transducer, a rotation speed sensor, a laser displacement sensor, a temperature sensor, a magnetic oil residue sensor, a pressure sensor, a flow sensor, an oil temperature sensor, an acceleration sensor and other related sensors used for bearing testing. The control system is driven in a servo mode, and is composed of a frequency converter, a hydraulic solenoid valve, a heating controller, a flow control device and a pressure control device. The environmental simulation system is adopted for simulating a real bearing testing working condition, and the performance and service life testing of the real bearing testing working condition is achieved.
