The PIglide RT series of nonmotorized passive rotary air bearings are designed for accuracy, precision, high stiffness, and ease of use. They can be used in any orientation and are easy to integrate with motors and encoders for complete positioning solutions.

The bearings of the RT series offer superior eccentricity, flatness, and wobble performance. Because they are completely friction-free, they exhibit no breakaway torque and no frictional resistance during operation. They are ideal for use in cleanrooms, require no maintenance or lubrication, and have unlimited lifetime.

Encoder for precise acquisition of stage angle during manual operation
Mounting base for horizontal mounting onto optical table and flat surfaces
PIglide filter and air preparation kits
Customized mounting flanges and square housings

Optical alignment, metrology, parts inspection, calibration, scanning, torque measurement.

Thanks to the friction-free motion, no particles are formed, which makes PIglide stages ideal for cleanroom applications.

⁽²⁾ Precision specifications are dependent on quality of mounting base, payload, orientation, and external forces on the bearing. For application-specific parameters, please contact PI. Values shown are static (no rotational velocity during measurement).

⁽³⁾ Velocity may be limited by the encoder option or payload imbalance. Please contact PI for further details.
