Non-Contact Linear Slide

      Illustrated is a tooling which describes a means for moving an
air bearing slide without use of a mechanical connection.

      An air bearing slide 1 (see the figure) provides the orifices
for all airflow into the assembly.  It creates its own air cushion
between itself and the granite 2, and between the bearing 1 and the
frame member 3.  The cushion between the bearing 1 and the granite 2
provides the horizontal stability of the slide itself to sustain a
10-20 microinch flyheight off the granite 2.  The bearing 1 also
creates an air cushion between itself and the frame 3 which keeps the
bearing centered within the four sides of frame 3 without touching
any of its walls.  Frame 3 is then driven by leadscrew 4 and nut 5
which controls the motion and accuracy of the frame and thereby the
bearing within.
