Aerotech: Linear Motor Drive Precision Stage (PRO280SL/SLE Series)

Linear Stages

Aerotech manufactures a large selection of positioning stages including linear stage models that utilize our own brushless linear direct-drive servomotors, as well as ball-screw models driven with Aerotech brush or brushless rotary motors. Innovators in linear stage design, manufacture and integration, Aerotech builds linear positioning stages for high-performance applications in industrial robots, fiber optics and photonics, vision systems, machine tools, assembly, semiconductor equipment, medical component laser machining, laser micromachining, electronic manufacturing, and other industrial automation applications.

Aerotech linear stages are available in X, XY and XYZ combinations to meet your motion requirements.

PRO280SL and SLE Mechanical Bearing, Ball-Screw Stage

Design Features

The PRO280SL and PRO280SLE are Aerotech’s second-generation
PRO280 stage designs with many improvements and added features. Enhanced positioning specifications coupled with competitive pricing make the PRO280SL/SLE stage the ideal choice for both medium and high-performance applications. The design is similar to the PRO225SL/SLE series, providing additional load capacity and stiffness with larger bearings and a wider cross-section.

Rugged Mechanical Construction

A long-life recirculating linear guide bearing system and a low-friction sealing solution make the PRO280SL/SLE an attractive solution for industrial applications such as laser machining. The basic external construction of the PRO280SL/SLE design provides protection from debris while the side-seals prevent dirt and particulates from entering the stage. The curved hard-cover design provides a natural shape that prevents excessive debris from collecting on the stage.

Linear Encoder Option

For applications requiring direct-metrology of the output carriage, the PRO280SLE integrates a direct linear encoder that is protected by the stage sealing system. Amplified sine, digital TTL output, and absolute encoders are available as standard options for linear feedback.

Design and Integration Flexibility

The PRO280SL/SLE is designed with many standard features and options that make the design incredibly flexible and allow it to be easily tailored to a specific application. The PRO280SL/SLE is available in 12 different models with travels ranging from 300 mm to 1000 mm and speeds up to 220 mm/s.

The base mounting holes are accessible from the outside of the stage allowing for easy mounting. Standard mounting holes for both English and metric optical tables are present in all travels. The tabletop is available with both English and metric mounting patterns and can be ordered with brush attachments to clear any debris that may collect on the stage hard cover. Tabletops with hole patterns that allow the direct attachment of Aerotech’s ADRS, ACS-LP, ADRT, ACS, CCS, ALAR, and AGR rotary stages are also available.

Aerotech BM or BMS series brushless servo motors are available with a variety of encoder options providing net electronic resolutions ranging from 0.5 μm down to sub-nm. A holding brake can be added to the motor for vertical applications. A motor fold back kit is available for space constrained applications to reduce the overall stage length.

The PRO280SL/SLE series is also available with cleanroom preparation and vacuum versions.
