Notes:
1. Maximum speed based on stage capability; maximum application
velocity may be limited by system data rate and system resolution.
2. Maximum load based on bearing capability; maximum application
load may be limited by acceleration requirements.
3. Available with Aerotech controllers and HALAR calibration option.
4. To protect air bearing against under-pressure, an in-line pressure
switch tied to motion controller E-stop input is recommended.
5. Air supply must be clean, dry to 0° F dew point, and filtered
to 0.25 µm or better; recommend nitrogen at 99.9% purity.
6. Requires vacuum preload.
7. Specifications are for single-axis systems, measured 50 mm
above the tabletop. Performance of multi-axis systems is payload
and workpoint dependent. Consult factory for multi-axis or non-standard
applications.
