Aerostatic thrust bearings have been widely applied to precision devices because of their excellent accuracy of motion. However, it was experimentally demonstrated that aerostatic bearings always caused the nanometer order of vibration due to low viscosity of air. This nanometer order of vibration became a major obstacle to achieve higher accuracy in precision devices and larger damping coefficient has been required to aerostatic bearings. In this paper, a water-lubricated porous thrust bearing for precision devices is proposed instead of aerostatic bearings. It can be expected that the proposed bearing can achieve larger damping coefficient than aerostatic bearings due to larger viscosity of water. The static and dynamic characteristics of water-lubricated porous thrust bearings were investigated numerically and experimentally and the usefulness of the proposed thrust bearing was confirmed.
