For the water lubricated radial bearing stiffness tests loading force and incentive force implementation, a electromagnetic excitation of radial load device has be developed. This device has been applied in a large aspect ratio water lubricated rubber bearing stiffness test. An octupole electromagnetic loading device has be designed and has be manufactured, such octupole constitutes four electromagnet, that device through the PID technology for static load, and dynamic excitation functions sine and shock, and it is able to achieve a small angle displacement contral for shqft; a magnetic monitoring software has been develaped,verified by experiments with electromagnetic loading device. The loading device is installed on a bearing test rig, and identifiying water lubricated rubber bearing stiffness values is 107N ＂m-1 volume. The results showed that： The magnetic device can achieve a static load and dynamic harmonic excitation function, and this technique can be used to test water lubricated radial bearing stiffness.
