Aerotech Intros Linear Motor Stage
Linear motion stage.
Pittsburgh, PA — Aerotech NanoTranslation (ANT95-L, ANT95-L- H) cross-roller bearing stages combine high speed, accuracy, resolution, repeatability, and reliability in a compact package. As an evolution of the popular ANT stage family, these linear stages exhibit enhanced motion performance such as 5g acceleration, 500mm/s velocity, enhanced load capacity, and standardized, universal base mounting patterns that allow the use of this flexible stage family in a wide range of configurations.

The stages utilize the company's advanced direct-drive technology to achieve the highest level of positioning performance with resolution of 5nm, repeatability of 50nm, and accuracy of 250nm. The company's direct-drive technology is non-cogging, noncontact, high speed, high resolution, and high accuracy, and the use of anti-creep cross- roller bearings allows ultra-precision (5nm) incremental moves to be accomplished reliably and repeatably. This unique drive and bearing combination, packaged in an extremely small-profile and footprint, offers tangible advantages in applications such as high-precision positioning, disk-drive fabrication, fiber alignment, optical delay element actuation, sensor testing, and scanning processes that demand smooth and precise motion.

The units have universal mounting and tabletop patterns that allow for easy system integration. Two, three, or more axes can be easily combined for flexible system designs and multi-axis configurations. According to the company, the high system resolution provides outstanding accuracy, position repeatability, and in-position stability. Its 5nm minimum incremental step size provides this high level of performance. Excellent in-position stability assisted by high-quality, anti-creep cross-roller bearings enables virtually maintenance-free operation over the life of the product. The direct- drive technology has no hysteresis or backlash, enabling accurate and repeatable nanometer-scale motion.
