Highly dynamic linear stage with air bearing

The drive concept of this linear axis is based on a dynamic linear motor and a linear measuring system, whereby it provides excellent flatness and straightness for highly dynamic applications. The granite structure with air bearings provides particle-free operation and a particularly long lifetime.

  • Ideal for particle-free, highly dynamic applications with high precision
  • Perfect flatness and high repeatibility up to ± 0.3 µm
  • Highly dynamic at speeds of up to 2060 mm/s
  • High load up to 50 kg
  • Suitable for maintenance-free 3-shift operation in clean room

Options:

  • Travels from 500 - 2000 mm
  • Versions for clean room, laboratory or production
  • Optionally with base plate and frame
  • Different measuring system resolutions up to 0.001 µm
  • Customized development with 3D design, prototypes, large series production

Fields of application

linear stage for precision scanning, setup of dynamic and highly precise multi-axis systems for cleanroom applications, semiconductor technology: wafer inspection, measurement of large substrates, TFT / OLED inspection, semiconductor printers for applying coating components, biotechnology: laboratory diagnostics, image-based inline monitoring, high-speed microscopy, laboratory automation

Nearly all atmospheric standard rotary stages shown here are optionally available in a non-anodized version with UHV-compatible lubrication for residual pressures up to 10E-6 mbar. In this configuration, they achieve at least cleanroom class ISO 6 - or better - making them suitable for demanding environments.

For higher requirements, specially designed rotary stage variants are available, for example for cleanroom class ISO 2, vacuum up to 10E-11 mbar, or harsh radiation environments.

The vacuum rotary stages are specifically engineered for high axial and radial loads. Reinforced bearing concepts, adapted material selection, and vacuum-compatible lubrication and coating systems ensure stable rotation even under high payloads and large moments of inertia.

Materials for Rotary Stages

Steinmeyer Mechatronik primarily uses aluminum for the structural components of rotary stages. This material provides an optimal balance of weight, stiffness, and thermal conductivity—critical for precise runout and repeatability.

Aluminum efficiently dissipates localized heat, for example from motor losses or bearing friction. As a result, the rotary stage quickly reaches a thermally stable condition—an essential prerequisite for consistent angular accuracy during continuous operation or high-dynamic motion.

The lower stiffness of aluminum compared to steel is compensated by design measures, such as:

  • Reinforced housing and bearing structures
  • Optimized wall thicknesses and installation heights
  • Hollow profile constructions with high torsional stiffness

For special requirements—such as high load capacities, vacuum-compatible designs, or magnetically sensitive applications—steel or titanium versions are available as alternatives.


Functional Surfaces and Coatings for Rotary Stages

In addition to standard finishes, numerous customized surface and coating concepts are available. These are specifically designed to achieve very high cleanroom classes—up to ISO 1–2, depending on the application and process.

To meet demanding process requirements, we develop and qualify application-specific functional coatings, including:

  • Nickel coatings
  • PTFE & KEPLA® coatings
  • Fluorinated lubricants
  • Dicronite® / dry-film coatings
  • Application-specific coating combinations

The following surface options are also available:

  • Anodized (cleaned)
  • Alternative anodized colors
  • Aluminum bare, cleaned
  • Bilatal
  • Nickel

These surfaces are particularly suitable for:

  • High cleanliness requirements in cleanroom environments
  • Vacuum applications
  • Chemically aggressive environments (e.g., life sciences)
  • Optical systems with stray light requirements


Why Functional Coatings Are Critical for Rotary Stages (Before → After)

  • Standard surface → EUV-compatible surface
  • Reflective → Non-reflective, minimized stray light
  • Standard sliding behavior → Optimized friction coefficients & reduced wear
  • Basic protection → Enhanced chemical & corrosion resistance
  • Standard configuration → Application-optimized performance

Special surface treatments are often required for UV / DUV / EUV applications (X-ray or gamma applications available upon request).

Yes. Our rotary stages can be modularly combined with linear, XY, or XYZ stages to form compact multi-axis systems (e.g., XYZ-R or Theta-Z). The required mechanical interfaces are already integrated into the design.

Typical Configurations


Advantages of the Combination

  • High system flexibility
  • Modular expandability
  • Space-saving integration
  • Precise coordination of rotation and translation


Technical Requirements

  • Matched mechanical interfaces (mounting pattern / centering)
  • Rotary stage load capacity designed for additional axes (Fx, Fy, Fz)
  • Consideration of moment of inertia and center of gravity
  • Synchronized control of all axes

For rotary stages, Steinmeyer offers standard motion controllers, PLC integration, as well as custom embedded solutions. Depending on torque requirements, dynamic performance, and installation constraints, the controller can be implemented externally in a control cabinet or fully integrated into the rotary stage module.
