AGR series motorized rotary stages provide significant improvements in speed, load capacity, and long-term positioning performance over previous generations of worm-gear-drive stages. AGR series stages address a wide range of applications for general purpose positioning in laboratory and industrial uses.

Innovative Gear Design
A unique preloading scheme avoids changing wear characteristics, allowing an orders of magnitude increase in stage life without any degradation in stage performance, and allows stage operation over a wide temperature range.

The addition of a larger clear aperture is a key enhancement over previous generations of worm-gear-driven stages. This feature allows the AGR series to address applications requiring a through-hole or accommodations to mount an optic, including articulation of beam polarizing lenses, through-holes for cabling and/or air lines, or vision/camera/inspection applications.

Other Construction Features
The AGR stage base is fabricated from a special aluminum alloy which offers significant weight savings in multi-axis arrangements and other weight critical applications, while providing high structural stiffness and long-term stability.

Each stage incorporates dual large diameter pre-loaded angular contact bearings optimally separated to provide excellent error motion specifications, as well as best possible load handling capability.

All stage tabletops feature aluminum hardcoat plating and stainless-steel Heli-Coil^®; inserts to prevent thread wear.

Flexible Options
Options include flexible motor selections as well as a direct encoder mounted concentric to the axis of rotation for outstanding repeatability and to virtually eliminate hysteresis and backlash. Vacuum-compatible versions (for use in pressures as low as 10^-6 torr) are also available.

Motor and Drives
Standard AGR stage configurations feature Aerotech’s brushless servomotors. However, all AGR stages can be outfitted with stepper or DC brush motors. A full range of matching drives and controls are available for a complete single-source solution.
