PI A-322 PIglide HS Planar Air-Bearing XY Systems Review: Specs, Price and Applications
A-322 PIglide HS is an XY planar scanning system combining magnetic linear motors, air bearings, a granite reference and specified digital control. PI identifies Base, Plus and Ultra performance classes. The architecture uses a flexural coupling to decouple lateral behavior between axes while preserving structural stiffness; performance is determined by the selected complete system and its calibration.
Quick Verdict
Consider A-322 for precision scanning and metrology where the installation can provide clean regulated air, a suitable foundation and thermal control. The supplied 350 ×500 mm,15 kg and 1 m/s figures describe a configuration scope, not every Base, Plus, Ultra or customized system.

Design and Engineering Assessment
An air bearing removes rolling-element contact during normal supported operation, but depends on air quality, pressure and the approved load distribution. Loss of supply must have a defined mechanical and operational response. Do not assume that a high-precision platform can tolerate contamination or unrestricted contact after an interruption.
Dynamic mapping and error compensation correct measured, repeatable errors within a calibrated scope. They do not eliminate fixture compliance, thermal drift or a changed payload’s effect. Preserve the calibration reference, environmental conditions and accepted compensation data with the system.
A submicrometer straightness/flatness headline must be tied to travel, performance class, load and test conditions. For scanning, velocity ripple and dynamic tracking can matter more than a static endpoint measurement. Specify the real measurement path and tool height.
Prepare Utilities and Foundation
Specify air filtration, regulation, vacuum preload and the approved loss-of-air response with the supplier. Match granite support, isolation and load distribution to the installed system.
Define controller, amplifier, encoder, metrology and compensation scope together. An advertised servo update rate is not an independent guarantee of axis bandwidth or process accuracy.
Calibrate and Accept the Scan
Measure geometry and dynamic tracking with the intended payload, service routing and environmental stabilization. Verify the useful workpiece coordinate system and scanning speed profile.
Store mapping data, controller software, tuning and foundation requirements. Payload, fixture or major environmental changes may justify renewed calibration rather than reusing the original error map unchanged.
Applications and Selection
Precision scanning, semiconductor inspection and metrology systems with controlled utilities and installation conditions.
For PI A-322 PIglide HS Planar Air-Bearing XY Systems, define the actual machine duty before selecting an ordering configuration. Include the required operating point, available installation space, environment and control interfaces. The specification table describes the product or family; the surrounding machine determines which of those features matters for the intended job.
Price and Value
Price: Request a quote for the exact configuration. Compare the product, compatible control equipment, required mechanical parts, cabling and commissioning as one installed system. A component price alone does not represent the cost of a working automation axis.
Evaluate an alternative against the same duty and acceptance criteria. Match the continuous operating requirement first, then compare transient capability, feedback, mechanical fit and support. This avoids choosing between superficially similar products whose ratings describe different operating conditions.
Pros and Cons
Advantages
Planar air-bearing architecture for precision scanning
Defined system classes and customization basis
Integrated control and applicable error-compensation tools
Limitations
Requires clean air and foundation/environment engineering
Quoted performance depends on system class and calibration
Utility-loss and service procedures are integral to operation
Who Should Consider PI A-322 PIglide HS Planar Air-Bearing XY Systems?
Consider PI A-322 PIglide HS Planar Air-Bearing XY Systems when the documented configuration matches the actual process, load, environment and control architecture. Use a representative installed cycle and a defined process-side error budget for acceptance.
PI A-322 PIglide HS Planar Air-Bearing XY Systems FAQ
Is A-322 a generic rolling-bearing XY table?
No. It is an air-bearing planar system with a specified granite and control arrangement.
Are Base, Plus and Ultra identical?
No. Match the selected performance class and delivered specification.
Does an air bearing need plant utilities?
Yes. Provide the specified clean regulated air and vacuum-preload arrangement where applicable.
Does error mapping eliminate thermal drift?
No. Compensation is valid within its measured and accepted conditions.
Are 350 ×500 mm and 15 kg universal family values?
No. They describe a source configuration scope; confirm the delivered system.
Does a 5 kHz update rate prove 5 kHz axis bandwidth?
No. Controller update, mechanical response and useful process performance are different.
What happens if air is lost?
Use the supplier-approved mechanical and control response; it must be defined for the installed system.
What belongs in acceptance?
Class/configuration, foundation/utilities, payload, calibrated geometry, dynamic scan tracking and restoration records.
Prices are indicative and may change. Confirm the final configuration, commercial terms and delivery schedule before ordering.
