Abstract
The invention contemplates use of a suction bell to enhance the loading with which a guided machine part is gravitationally supported on its guide. In application to a machine in which the machine part is movably supported on air bearings, the suction bell applies a preload force of magnitude to optimize the stiffness of air-bearing action and to maintain an air gap of uniform capillary thickness, free of mechanical contact between the machine part and its supporting surface.
