Aerotech (Pittsburgh, PA) offers the PRO series industrial linear motor and ball-screw positioning stages, including two new sizes of the PRO-LM (linear motor) series stage line: the PRO115LM and PRO190LM. New features include a linear encoder option on PRO-SLE ball-screw stages, absolute encoder options on both the linear motor and ball-screw stages, and direct mounting to English and metric optical tables. All stages employ a recirculating linear guide bearing system and a low-friction sealing solution. The design provides protection from debris while side seals prevent dirt and particulates from entering the stage.

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. Incremental and absolute encoders are available as standard options, and enable minimum incremental motion down to 5 nm and sub-micrometer repeatability.
