Air-Bearing Rotary Tables

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/25mm). 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/25mm). Air bearings provide significant advantages over mechanical bearings or other approaches to precision worktables. 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.

Superior Durability

Metrology is no longer relegated to the quality control lab. To maximize productivity, we know many applications require integrating measurement devices within the production and assembly processes. This means being exposed to harsher environments, ABTech uses hardened 440C stainless steel components – so you’ll experience many years of service and investment longevity.

Configuration Flexibility to Meet Your Specific Needs

Part of our “Pride in Precision” philosophy means providing you with the precise solution needed. We don’t believe in selling our customers more, or less than what their application calls for. For over two decades working with our customers, we’ve developed a broad range of options and accessories to address the majority of ultra-precision motion applications. (See options and accessories for a complete list.)

No matter how broad our product options are, we realize they don’t address every possible application. Our precision motion experts will work closely with you to configure a rotary motion solution that will meet your exact needs.
