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.

• Superior Durability

  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.

ABTech’s precision air bearing rotary tables address the metrology needs for different weights and part size. Built for the most demanding applications, every table 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 allows for decades of reliable maintenance-free motion.

ABTech’s AT models come standard with dual element filter/regulators and are commonly used as the core axis in equipment checking total indicator reading (TIR), roundness, flatness, squareness, perpendicularity, concentricity and parallelism measurements. They are ideal as stand-alone units for checking runout of turned parts, optical lens alignment, assembly applications, precision indexing, and light machining or grinding.

The heavy-duty HDRT tables complete the product family. They are a perfect solution for large part applications.

To speed part setup and increase productivity, the AT model tables come standard with our industry-best adjustable tilt and center (tip/tilt) work-tables. The tilt and center are optionally available on the HDRT models.

We understand metrology needs often require operating in harsher environments. We use the most durable hardened 440C stainless-steel air bearing. This affords forgiveness from minor accidental touch downs that may result from low air pressure, excessive loading, or operator error.

All rotary tables can be customized with a variety of options and accessories including motor drives, vacuum worktable (AT Series), high-resolution optical encoders, digital readout (DRO) displays, inspection-grade granite surface plates and gage stands.

If our standard tables don’t fit your application, our precision motion experts will work closely with you to configure a rotary motion solution that will meet your exact needs.

ABTech’s high precision air bearing spindles provide the ultimate performance utilizing a proven and robust design. High stiffness, load capacity and very low error motion make these spindles ideal for precision machining, grinding, single point diamond turning, and high precision scanning. Available with integral brushless dc motor and encoder in low speed configurations for work holding or higher speed for grinding and scanning applications.

These orifice compensated air bearing spindles use a single piece of 440 CSS shaft and thrust plate with 660 bearing bronze journal providing a proven, robust and forgiving design. Available in a variety of sizes and speeds with a flange, foot, or a-thermal mounting.

Optional motion controllers incorporate a digital amplifier with easy-to-use programmable controls and digital spindle speed readout. Fully integratable with your existing CNC controller.

With this modular design approach and complete engineering support capabilities ABTech will respond quickly to provide a custom solution to your unique O.E.M. needs for ultra-precision motion. No need to settle for standard catalog offerings for your application.
