Linear Positioning Stages
Aerotech's ATX features anti-creep crossed-roller bearings and a precision-ground, fine-pitch ball-screw, with up to 250 mm of nominal travel.
Aerotech’s ATX series 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. Featuring anti-creep crossed-roller bearings and a precision-ground, fine-pitch ball-screw, the ATX series offers excellent geometric performance and minimal angular error motion. With up to 250 mm of nominal travel, these linear stages offer minimum incremental step size and in-position stability. This makes the ATX series ideal for many high-precision tasks such as vertical positioning of sensors and cameras, optics focusing, and beamline measurement and manipulation applications. The ATX series is designed with a variety of standard features and options allowing them to be easily integrated into a larger subsystem or machine, or to serve as a stand-alone positioning axis. They mount to both metric and English optical tables and feature a versatile customer mounting interface on the moving carriage to which other positioning stages or equipment can be mounted. Brushless, slotless servomotors, with or without a holding brake, as well as stepper motors are available. The ATX series can be equipped with an optional motor foldback kit in order to reduce the overall length of the stage. This is particularly useful in vertical-axis applications where space is limited. Vacuum- and cleanroom-compatible variants are also offered.
