Aerotech ABRX High-Performance Rotary Air-Bearing Stages

Design Features

• Delivers best-in-class rotational motion, helping you to optimize your

high-precision process

• Minimizes axial-, radial-, and tilt-error motions, reducing the need for

extensive post-processing of parts and measurement data

• Offers excellent positioning performance and velocity stability with

high-resolution feedback

• Features a novel, non-influencing motor design that contributes to

ultra-precise motion performance

• Provides generous load-carrying capacity without compromising on

motion quality

• Integrates easily into precision systems and machines due to compact,

lightweight form factor, as well as horizontal and vertical mounting and

load-carrying capabilities

Key Applications

• ABRX stages are ideal for high-precision applications, including:

• Surface metrology, including the measurement of roundness, flatness,

and form error

• Micro- and nanotomography

• Beamline and synchrotron research

• Precision manufacturing, including diamond turning, grinding and other

high-performance machine tool applications

• Optical alignment, inspection and calibration systems

Engineered for Precision

The ABRX series is meticulously engineered to consistently satisfy even

the most stringent performance requirements. At its core is an industry-

leading, air-bearing technology that delivers nanometer-level error motion

performance with high stiffness and load-carrying capabilities.

The non-influencing, direct-drive, ironless motor was specifically engineered

to have virtually zero contribution to axial-, radial- or tilt-error motions,

without compromising torque or speed. Coupled with a selection of analog

and digital position feedback configurations, including an ultra-fine resolution

one volt peak-to-peak (1 Vpp) option capable of achieving sub-microradian

minimum incremental motion, ABRX is the ideal rotary stage for applications

in which precision is non-negotiable. To this end, all ABRX stages ship with

certified plots of calibrated accuracy, repeatability and error motion performance.

Simple, Straightforward Integration

ABRX features an advanced bearing design that provides excellent stiffness

and high load capacity, while maintaining compact overall dimensions and

reasonably low overall mass. This makes ABRX ideal to use as a component

stage in multi-axis motion systems and precision turnkey machines.

ABRX stages can be mounted with the axis of rotation oriented either

vertically or horizontally. For interfacing with your payloads, the ABRX tabletop

is ground flat to minimize distortion and features 12 steel-threaded holes for

convenient load placement and orientation. Additionally, a clear aperture

through the center of the stage can be used for cable and hose routing or for

aiding system-level alignments.

Maintenance-Free Operation

The ABRX’s completely contactless air-bearing and non-influencing motor

design ensures years of maintenance-free operation. Zero contact between

moving elements means there is no wear or reduction in performance over

time, enabling consistent, high-precision motion over a virtually unlimited

service life.

Take Your Process to the Next Level

ABRX can achieve the extreme levels of motion and positioning performance

required by even the most demanding processes, enabling you to achieve

and maintain a competitive advantage while also minimizing risk. Its pristine

motion quality minimizes parasitic errors, which allows you to achieve the

highest possible processing quality and yield, while minimizing or eliminating

the need to perform extensive post-processing operations.
