Aerotech’s AGR series of precision worm-drive rotary stages features large through-apertures and a preload scheme that provides outstanding levels of accuracy and repeatability with minimal wear.

The series also provides an order of magnitude increase in stage life over competitive gear-driven rotary stages.

The AGR series covers five models with internal diameters from 50 to 200mm and is available with continuous 360-degree travel, or with a mechanically limited travel-range (down to five degrees).

Axial load capacity is up to 570kg and rated speed is up to 30rev/min.

The range includes optional directly mounted encoders for best performance repeatability and negligible levels of hysteresis and backlash.

Typical specifications across the AGR series include a 120 arc-sec positional accuracy without encoder fitted and 20 arc-sec when the servomotor mounted encoder option is used.

Corresponding without- and with- encoder specifications for bidirectional repeatability are 30 arc-sec and eight arc-sec.

Stage resolution, with a 2500-line servomotor mounted encoder fitted on the largest stage, is 2.1 arc-sec – while the same sized stage with a directly mounted 40000 lines per revolution encoder achieves 32.4 arc-sec.

The AGR series is aimed at general-purpose rotary positioning applications in research, industrial production and manufacturing test applications.

It accommodates the through-aperture mounting of additional equipment and services such as lenses, mirrors, slip rings or cable assemblies on high-precision positioning systems.

The main housing and table top are manufactured from a special lightweight aluminium alloy that ensures maximum structural stiffness and a reduced mass for multi-axis set-ups and other weight-critical applications.

The AGR series also benefits from a larger dual pre-loaded angular contact bearing-set to provide the high load-handling required for offset and awkward payloads, while maintaining the minimal error-motion performance required for high-precision positioning.

Other AGR series options include a choice of Aerotech’s high-performance brushless servomotors or stepper motors in various orientations with rear shaft-mounted encoders and brakes.

A labyrinth sealing kit is also available for stage sealing in arduous machining environments; vacuum compatible versions are available for levels down to 10-6torr.
