ABL10000Gx2 Custom Linear Positioner


Design Features

  • Granite stage, stainless-steel carriages
  • 1 m travel for each carriage
  • 0.25g, 250 mm/s with 5 kg load
  • ±2.5 µm straightness, ±5 µm flatness
  • ±2.5 arc-sec roll, pitch, yaw
  • ±1 µm accuracy calibrated, ±0.6 µm repeatability
  • 50 kg load capacity per carriage
The dual stainless-steel carriage, linear air-bearing stage provides exceptional straightness, flatness, roll, pitch, and yaw performance for testing, optical metrology, and laser processing applications. It can be used in horizontal (as shown), inverted, or upright applications. The granite base provides excellent stiffness and thermal stability

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

  7. 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 degrees C/24 hours.  If this is not possible, alternate products are available.  Please consult Aerotech Sales Engineering for more information.
