Claims

[Scope of utility model registration request]

In a static air bearing that has an orifice that blows out pressurized air onto the bearing pad surface and a continuous restriction groove in an arbitrary pattern formed in the orifice, the groove depth or groove width of the restriction groove is gradually increased from the orifice to the outer circumference. A hydrostatic air bearing consisting of a set.
