Aerotech, Inc. Mechanical Bearing, Ball-Screw Stage PRO280SL and SLE

Design Features Improved second-generation design High-performance in a cost-effective package Rugged mechanical construction Optional linear encoder 12 models with travels from 300 mm to 1000 mm Vacuum and cleanroom versions available 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 servomotors 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 foldback kit is available for spaceconstrained applications to reduce the overall stage length. The PRO280SL/SLE series is also available with cleanroom preparation and vacuum versions.
