ABTech’s precision air bearing linear stages address the motion needs for a full range of part sizes and weights. Built for the most demanding applications, every stage provides ultra-smooth motion, sub-micron accuracy and absolute repeatability. Designed and manufactured in-house to extremely tight geometric tolerances, air bearings have no mechanical contacting parts to wear or create drag. This affords forgiveness from minor accidental touch downs that may result from low air pressure, excessive loading, or operator error.
Our linear stages come standard with dual element filter/regulators and are commonly used as the core axis in a wide range of applications where smooth and repeatable motion is desired. They are ideal as stand-alone units and/or multi-axis assemblies, for position measurements, optical scanning, light machining and grinding, and more.
ABTech’s quality, accuracy, and design flexibility are the reasons our air bearings are meeting the ultra-precision motion demands.
Precision motion comes in many forms and applications, each with their own set of pertinent specifications. Diversity in today’s applications creates unique requirements, we provide configura¬tion flexibility as an integral part to our design philosophy. All linear stages can be customized with a variety of options and accessories including motor drives, vacuum carriage top, high-resolution optical encoders, digital readout (DRO) displays, inspection-grade granite surface plates and more.
Features & Benefits
Accurate, Repeatable, Smooth Motion
Air bearings provide significant advantages over mechanical bearings or other approaches to linear motion. 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. Manufactured with tight geometric tolerances, our standard air bearings stages are able to deliver arcsecond pitch, roll and yaw.
ABTech uses hardened 440C stainless steel components to maximize productivity with applications that require integrating motion systems into production and assembly processes with exposure to harsher environments. Durability of our stages affords forgiveness for minor accidental touch downs resulting from low oil pressure or excessive loading. If an accident occurs, often the bearing needs repair rather than replacement.
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 selling our customers more, or less, than what their application calls for. Each ABTech Linear Stage is designed and built per your specific needs. There is not a standard specifications sheet or drawings on our website. Each linear stage is uniquely adapted to our customer, therefore expectations are always met and exceeded. 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, 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.
