How to Select and Install Air Bearing Stages

Jan 11, 2008· An excellent choice for a complete motion subsytem is a linear or rotary stage that uses an air bearing for guidance, coupled to a direct-drive motor, a high-resolution position encoder, and a digital controller. Air bearings support a load with a thin film of pressurized air between the fixed and moving elements.

How Air Bearings Work :: Loadpoint Bearings

How Air Bearings Work. The basic principle of operation of air bearings has been established for more than fifty years. An air bearing may comprise of a sleeve separated from a plain shaft by a small gap, typically 5–50 um. High pressure air is fed through small orifices in the sleeve through to the bearing gap where it flows along the gap
