What is an Air Bearing? - Celera Motion

An air bearing is a non-contacting system where a gas film (usually air) acts as the lubricant that separates the two surfaces in relative motion – typically this being a rotating shaft, and a stationary radial journal or axial thrust bearing.

Measuring roundness/rotary table repeatability

Apr 23, 2021· If you are looking for single-digit micron measuring accuracy, you are in air-bearing rotary table territory. I don''t think a "standard" rotary table made for machining will give you this level of sensitivity. Of course, if you manage to get your hands on a Moore or SIP rotary table, you may be closer to your target.

Air Bearing Rotary Tables and Motorized Linear Air

The rotary air bearing on the left is non motorized – its low friction is apparent from the long time it keeps spinning. The smaller A-623 rotary air bearing stage on the right is equipped with a torque motor and high resolution encoder (0.024 µrad). It is driven by an PI / ACS motion controller. PI rotary air bearings provide extremely
