Features & Benefits
Accurate, Repeatable, Smooth Motion
Manufactured with tight geometric tolerances, our standard air bearings deliver radial and axial error motion of <2.0 µ” (50.0 nanometers) and angular errors (coning) of 1.0 µ” per inch (25.0 nanometers/25nm). And custom configurations can deliver the ultimate in accuracy with radial and axial error motion of as little as 1.0 µ” (25.0 nanometers) and angular errors (coning) of 0.5 µ” per inch (12.5 nanometers/25nm).
Air bearings provide significant advantages over mechanical bearings or other approaches to precision worktables. Because they have no mechanical contacting parts to wear, or create drag, air bearings are close to frictionless, providing ultra-smooth, repeatable and maintenance-free motion.
Metrology is no longer relegated to the quality control lab. To maximize productivity, we know that many of your applications require integrating measurement devices within the production and assembly processes. That means being exposed to harsher environments. That’s why we use hardened 440C stainless steel components – so you’ll experience many years of service and investment longevity. As important, the durability of our tables affords forgiveness for minor accidental touch downs resulting from low air pressure or excessive loading. And if an accident does occur, often the air bearing will only need to be repaired rather than completely replaced.
Configuration Flexibility to Meet Your Specific Needs
Part of our “Pride in Precision” philosophy means providing you with precisely the solution you need. We don’t believe in selling our customers more, or less, than what their application calls for. With almost two decades of listening to our customers we’ve been able to develop a broad range of options and accessories to address the majority of ultra-precision measurement applications. (See options and accessories for a complete list.)
But no matter how broad our product options may be, we realize that they can’t address every possible application. And that’s what separates ABTech from most other metrology suppliers. We won’t say sorry, best of luck. Rather, we’ll connect you with one of our precision motion experts and work closely with you to configure a rotary motion solution that will meet your exact needs, including developing custom solutions for the most unique applications.
