Manual Air Bearing Slides

ABTech inc offers a full line of ultra-precision air bearing linear stages for applications requiring ultra-precision linear motion, such as linear straightness measurement, linear positioning, high-velocity, ultra-smooth, constant velocity and linear systems requiring no static friction. Standard slide and carriage designs or custom engineered for customer specific application.

LAB series linear air bearing stages are ideal modular components for wafer scanning systems, computer-to-plate systems, linear measurement and vision systems, and pick-and-place production automation where precision positioning is required.

ABTech's modular design approach and full engineering services can respond quickly to provide a solution to your O.E.M. needs for ultra-precision frictionless linear motion.
