• Aerostatic bearings
• Bearing characteristic
• Compound structures
• Flow capacity
• Hydrostatic thrust bearings
• Optimizing parameters
• Sector cavity multi-pad
• Static stiffness

Static bearing capacity and static stiffness of pressure equalizing groove cross section with the same width and depth are researched in this paper, it can conclude that the trapezoidal section has the maximum static bearing capacity and static stiffness, while air consumption rate of unit load is the lowest. When compound structure annular hydrostatic thrust bearing has had the optimizing parameters, compared with the single structure one, the bearing capacity had a substantial increasing.
