For the highest precision applications, Nelson Air has developed a number of Planar XY air bearing stages. These systems use air bearings which ride directly on a granite or aluminum base. By eliminating the height stackup and overhung loads typical of stacked stage designs, planar air bearings achieve flatness of travel equal to or better than the actual flatness of the base. In addition, these systems have superior stiffness and load capacity. Finally, because the repeatability of air bearings is much better than mechanical bearings long travel systems can be calibrated for extremely high accuracies.
Many sizes, configurations and materials are available.
