PIglide Miniature Linear Air Bearing Stage High Performance • Cleanroom-Compatible • Option for Vertical Mounting Size of the motion platform 85 mm × 75 mm 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. 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...
