Air Bearing Rotary Tables and Motorized Linear Air Bearings | PI

Rotary Air Bearings provide High Precision Motion with Minimal Eccentricity and Wobble. 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 small radial runout errors, excellent velocity smoothness and high stiffness. Air bearings are clean room compatible and free of wear and maintenance.

Run Time - 0:57mins
