Aerotech ATX Linear Stages

Mechanical-bearing, screw-driven linear stage




Aerotech's ATX linear positioning stages combine the performance capabilities of a high-precision crossed-roller-bearing positioner with the convenience and simplicity of a ball-screw drive mechanism. Outstanding motion performance and a variety of advanced options and features offer superb value and make the ATX an excellent choice to use in high-performance applications.



  • Travel lengths up to 150 mm (ATX115) or 250mm (ATX165) with anti-creep crossed-roller bearings
  • Optional centre-mounted linear encoder for direct position feedback
  • Versatile features and options enable convenient integration into a larger machine or use as a standalone positioning axis
  • Vacuum- and cleanroom-compatible versions available
  • Available with ThermoComp® for reliable performance in changing environments

Superior Motion Performance
Featuring anti-creep crossed-roller bearings and a precision-ground, fine-pitch ball-screw, the ATX boasts excellent geometric performance and minimal angular error motion. With up to 150/250mm of nominal travel, the ATX offers superior minimum incremental step size and in-position stability compared to other stages that utilise recirculating ball bearings. This makes the ATX ideal for many high-precision tasks such as vertical positioning of sensors and cameras, optics focusing, and beamline measurement and manipulation applications.


Linear Encoder Option
The ATX offers an integral center-mounted linear encoder to provide direct position measurement at the stage’s moving carriage. The typical effects of backlash commonly associated with screw drives are virtually eliminated when using the linear encoder as a position feedback device. Applications that require exacting workpoint performance benefit greatly from the ATX115SLE’s direct linear encoder. Options are available with either incremental (1 Vpp and digital TTL) or absolute output signals.
