February 19, 2018 - Aerotech’s ATX series linear positioning stages combine the a crossed-roller-bearing positioner with a ball-screw drive mechanism.
Featuring anti-creep crossed-roller bearings and a precision-ground, fine-pitch ball-screw, the ATX series is designed for geometric performance and minimal angular error motion. The ATX series is designed for many high-precision tasks such as vertical positioning of sensors and cameras, optics focusing, and beamline measurement and manipulation applications.
ATX stages offer an integral center-mounted linear encoder to provide direct position measurement at the stage’s moving carriage. Options are available with either incremental (1 Vpp and digital TTL) or absolute output signals.
The ATX series is designed with a variety of standard features and options allowing them to be 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 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.
All ATX-series stages are available with Aerotech’s ThermoComp feature, an integrated temperature compensation solution that delivers positioning performance in the presence of thermal disturbances. It protects the stage from the effects of variable-temperature environments and friction-induced self-heating.
