Key Applications

PRO280SL mechanical bearing, ball-screw stages are extremely versatile, trusted and proven in medium- and high-performance applications, such as:

Laser material processing
Precision metrology, inspection & microscopy
Electronics & circuit board manufacturing & inspection
Display processing
Synchrotron & light source experiments
Medical device manufacturing
Semiconductor fabrication
Fiber optics & silicon photonics processing
Additive manufacturing & precision assembly

Rugged & Reliable Mechanical Construction

A long-life recirculating linear guide bearing system, a precision-ground ball screw and a low-friction sealing solution make the PRO280SL an attractive choice for industrial applications such as laser machining, precision metrology, and electronics manufacturing and inspection. The PRO280SL’s durable construction provides protection from debris while the side seals prevent particulate matter from entering the stage. The curved hardcover design provides a natural shape that prevents excessive contamination from collecting on the stage. Capable of accommodating an ample payload range, PRO280SL stages are easy and intuitive to integrate, set up and operate. They also deliver an exceptionally long lifetime of consistent positioning performance.

Design & Integration Flexibility

The PRO280SL is designed with many standard features and options that make it incredibly flexible and allow it to be easily tailored to your specific application. The base mounting holes are accessible from the outside of the stage, allowing for easy horizontal or vertical mounting to both metric and English optical tables and other interfaces. The stage tabletop comes standard with a metric mounting pattern to accommodate your payload, process equipment or even another axis of motion.

Brushless servo motors are available with a variety of encoder feedback options, providing electrical resolutions ranging from 0.5 µm down to the sub-nm level. For vertical applications, the motor can be equipped with a fail-safe holding brake.

PRO280SL stages can be prepared for use in special environments by request. Contact us to learn about compatibility in vacuum chambers, cleanrooms and more.

Automate with Professional-Grade Motion

Our PRO-series stages are available in many sizes and configurations to accommodate an equally diverse range of user needs and application requirements. In addition to the PRO-SL series of ball-screw stages, we offer PRO-LM direct-drive linear stages, which are equipped with powerful linear motors for smooth, high-dynamic performance. PRO stages are offered in six widths ranging from 115 mm to 560 mm (depending on your application’s space constraints and payload requirements) plus travel lengths ranging from 50 mm to 1000 mm or longer. Also available in a vertical elevator-stage variant, our PRO-SV long-travel lift stages offer heavy-duty lifting capacity and can be easily mounted to PRO-SL and PRO-LM linear stages.

Aerotech PRO-series stages make it easier to build and integrate multi-axis assemblies and motion systems–whether you prefer to do it yourself or leave it to our motion and automation professionals.
