ABSTRACT:
A non-contact type hydrostatic linear guide device includes a guide unit having a pair of rail parts on the top surface thereof, and a slide unit having oil pockets in a running surface thereof. A load of the slide unit concentrates on the frame of the guide unit. The slide unit has a stepped leg structure in which projections are disposed in the under surface of a table thereof in bilateral symmetry. The projections contact the top surface of inner projections disposed on the guide unit and the outer side surfaces thereof face the inner surfaces of the wear plates disposed on the guide unit, and wear plates are placed outward in the midway of the under surfaces of the projections as the side surfaces thereof face the both side surfaces of the first recessed part and the third recessed part of the guide unit.
