Abstract: An air bearing comprising a static shaft having a circumferential surface in a form which when developed into a substantially flat plane takes the form of a series of shallow sinusoidal waves having at least three wave peaks, wherein one of the peaks carries a groove extending longitudinally parallel to the shaft axis and which bearing further comprises a hollow support member mounted for rotation around the static shaft.

Abstract: A collet for carrying a high-speed drill which comprises a collar (2) arranged to enclose a drill shank (1), an outer rim support (8) arranged for attachment to a drill, and a clamping mechanism between the collar and the outer rim support (8). The clamping mechanism is arranged to provide clamping forces between said outer rim support (8) and said collar so that said collar tightly grips a drill shank (1), as a consequence of centrifugal forces and of off center sprag effect forces.
