Product overview
The PIglide miniature linear stage with air bearing has a linear motor drive, preloaded air bearings, and an integrated optical linear encoder. This stage provides very high precision with a small footprint. The combination of noncontact components results in frictionless motion that offers outstanding dynamic performance, nanometer precision positioning, and an exceptionally long lifetime.
To set up an XYZ system, the vertical mounting option is available for the A-143, including brake and counterbalance.
Accessories and options
- PIglide filter and air preparation kits
- Single and multi-axis motion controllers
- Models with brake and pneumatic counterbalance for vertical mounting
Application fields
The stage is ideally suited for many high-precision and highly dynamic applications, such as metrology, inspection, fiber positioning, optics positioning, scanning, and patterning. With the noncontact design that requires no lubrication and a securely attached cable, the linear stage is ideal for cleanroom and medical technology applications.

Note on linear crosstalk: Dependent on the flatness of the surface, on which the stage is mounted.
Note on minimum incremental motion: Is directly related to the system stability (servo jitter); this depends on the servo drive used.
Note on positioning accuracy: The calibrated accuracy can only be achieved with a controller-driven error compensation. The stage must be ordered with a controller from PI to reach these values. Accuracy values assume short duration and do not consider the long-term effects of thermal drift on the stage.
Note on permissible push force in X: Value applies for vertical mounting
Note on permissible push force and moment: Assumes an operating pressure of the air bearings of 517 kPa (75 psi).
Note on operating pressure: To protect the stage against damage, it is recommended to connect an air pressure sensor to the E-Stop input of the controller.
At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.
