Owing to all the advantages of angular contact ball bearings (ACBB), including little energy consumption and low friction, etc, ACBB becomes the prior options for supportive components of NC machine tool spindle units. Thermal and mechanical behaviors of rigid-preloaded-ACBB are highly coupled, which produces the thermal preload. For investigating the effects of thermal preload on the bearing performances, this paper presents an ACBB thermo-mechanical information interaction net which is constructed on a collaborative computing platform. During the case study process, the thermo-mechanical information interaction net of a NSK ACBB 70BNR10X is realized. Thermal preload of the given ACBB is then predicted and analyzed through the information interaction net. In addition, effects of thermal preload on the ACBB operational stiffness are studied. With the help of temperature inspecting instrument, temperature tests are provided on the bearing thermo-mechanics test platform to validate the interaction net. Great agreements are found between the results predicted by the interaction net and the datum obtained through experimentation. The proposed information interaction net is useful for investigating the behaviors of running-bearing.
