Mechanical Linear Stages

ABTech’s line of precision mechanical bearing linear stages address the motion needs for a full range of part sizes and weights. High precision cross roller linear guide rails are incorporated into stages that are designed and manufactured in-house to extremely tight geometric tolerances. The result is superior performance in travel straightness, smoothness of motion, high stiffness, repeatability and accuracy.

Mechanical linear stages are used in a wide range of applications where a combination of lower-cost & high-performance motion is required. They are ideal as stand-alone units and/or multi-axis assemblies, for assembly and alignment tools, position measurements, optical scanning, light machining and grinding, and more.

Quality, accuracy, and design flexibility are the reasons why our stages are meeting the ultra-precision motion demands in industries and applications such as aviation, aerospace, automotive, energy (gas, oil and wind), precision optics, bearings, semiconductors and medical devices.

Precision motion comes in many forms and applications, each with their own set of pertinent specifications. Because the diversity of today’s applications creates many unique requirements, providing configura¬tion flexibility is integral 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.

In addition to the above configurations, the material selection of linear stages is a key focus of our applications engineer(s). For the harsher environments and/or the best accuracy, precision and stability we will choose hardened stainless-steel components. Whereas, if your application is focused on cost, we can utilize the efficiencies of hardcoated aluminum construction. With nearly endless possibilities at their disposal, our precision motion experts can work closely with you to configure a linear motion solution that will meet your exact needs, including developing custom solutions for the most unique applications.

Features & Benefits

  • Superior Mechanical Motion

    By leveraging our knowledge and experience gained in producing the extreme tolerances required for air bearings, ABTech mechanical stages are superior in performance and quality. While cross-roller guides can be purchased from many manufacturers, the key to a high-performance stage is in the geometry and overall quality of the mating components.

  • 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. Each ABTech Linear Stage is designed and built per order in the effort to tailor the solution to your specific needs. This is why you won’t find a standard specifications sheet or drawings on our website. Each linear stage is uniquely adapted to each customer so that expectations are always met and hopefully exceeded. With over 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 motion 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 motion 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 linear motion solution that will meet your exact needs, including developing custom solutions for the most unique applications.

Motor Drive Options

With proper selection and integration of high-performance brushless DC servo motors ABTech’s mechanical linear stages provide “near air bearing” accuracy and precision. The motor drives are designed to accommodate a wide range of precision motion applications such as optical metrology, or machining and grinding. Depending on your specific application we can also use many other motor drive approaches including stepper motors with precision ball screws.

Our precision motion experts will gather your specific requirements and work closely with our motor suppliers to create/select a motor drive that suits your specific application. Whether you need micron level position accuracy with minimal settle time and stringent following error specifications, or high-speed constant motion, or a combination of both there is an ABTech linear stage that will meet your needs.

ABTech’s modular design approach facilitates multiple system configurations to optimize the price-for-performance required in your application. Our complete engineering services allow us to respond quickly to provide a solution to your O.E.M. requirements for ultra-precision linear motion.
