An aerostatic bearing including a first bearing surface (28); a second bearing surface (32) which is juxtaposed to face the first bearing surface (28) and at least one fluid inlet (38) provided in one of the first and second bearing surface (28), (32). An inlet restriction (40) for restricting a flow rate of compressible fluid to and/or from said fluid inlet (38) and at least one recess (34) are provided in one of the first and second bearing surfaces (28, 32); the or each said recess (34) being in fluid communication with the or each said fluid inlet (38). There is also provided at least one outlet restriction (35) which is in fluid communication with the said at least one recess (34) and which restricts a flow rate at which compressible fluid exits the bearing; and at least one protrusion (42) which is provided on a surface defining at least part of the said at least one recess (34). The/each protrusion (42) lies entirely within said at least one recess (34). |
