Air bearings are used in all kind of high accuracy applications like positioning systems, wafer steppers, and measurement machines, which all demand an ultra high motion precision. These air bearings support and guide objects on a thin film of air with air gaps below 10 μm. They take care of near absolute repeatability, friction free movement and very low vibration levels, making high accuracy measurements possible.
