Available with Aerotech controllers.
Speed and acceleration based on 5 kg load.
Maximum load based on bearing capability. Maximum application load may be limited by acceleration requirements.
Specifications are for single-axis systems measured 25 mm above the tabletop. Performance of multi-axis systems is payload and work-point dependent. Consult factory for multi-axis or non-standard applications.
To protect air bearing against under-pressure, an in-line pressure switch tied to the motion controller/amplifier ESTOP input is recommended.
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.

Note: To ensure the achievement and repeatability of the specifications over an extended period of time, environmental temperature must be controlled to within 0.25°C/24 hours. If this is not possible, alternate products are available. Please consult Aerotech Sales Engineering for more information.
