The aerostatic bearing with a bearing foot

Aerostatic bearing with a bearing foot (2, 23), the front a flat bearing surface (3, 28) with a perpendicular central bearing axis and the rear via a support bearing on a holder (1) of the bearing is tiltably mounted, wherein arranged in the vicinity of the bearing axle support bearing is constructed as solid joint (9), characterized, that at the sides tiltable bearing foot (2, 23) in addition to the solid-body joint (9) outside the bearing axis, a bending spring (11) attached, whose attachment point perpendicular to the bearing surface (3, 28) is deflectable and has a lateral stiffness which twisting the bearing base (2) prevents the bearing axis.
