Aerostatic journal bearings with compound restrictors have been often used in high speed spindles because of low friction and high accuracy of motion. However, they also have disadvantages such as lower bearing stiffness and smaller load capacity than hydrostatic bearings. We, therefore, propose the method to increase bearing stiffness and load capacity by raising supply pressure to the medium pressure region. In this paper the dynamic characteristics of aerostatic journal bearings with compound restrictors in medium supply pressure region are investigated numerically and experimentally.
