The ABL8000 air bearing positioning stage provides tolerances beyond the capability of conventional ball-screw and mechanical-bearing positioning systems, with its air-on-air preload, exceptionally high stiffness and excellent geometric characteristics.
The ABL8000 incorporates an active preload on both the vertical and horizontal surfaces. The opposing thin-film pressure maintains the bearing nominal gap tolerance. This design, in addition to the large air-bearing surface that distributes the load over a large surface area, results in a stage with outstanding stiffness that is ideal for heavy or offset loading.
Proprietary manufacturing techniques result in a stage with unsurpassed geometric characteristics. The air bearing has an inherent averaging effect that maximizes performance. The thin film will fill small surface voids and allow for other irregularities. This characteristic yields superior pitch, roll, yaw, straightness and flatness specifications.
Design Features of the ABL8000 Air Bearing Positioning Stages Include:
Active air preload on all air-bearing surfaces
Travel to 1 meter
Linear encoder or laser interferometer feedback
High stiffness for heavy loads and excellent geometric performance
Integrated XY subsystems including granite
