ABTech inc designs and manufactures rotary and linear ultra-precision motion products for aircraft and aerospace; optical; semi-conductor and other high-tech research, metrology and production applications. 

We specialize in friction-free, low maintenance hydrostatic air bearings with sub-micron accuracy and extreme load and stiffness capabilities. In addition to our air bearings we have developed numerous oil hydrostatic and high precision mechanical bearing options.

Choose from one of our many standard component designs or consult with our engineering team to develop a unique multi-axis or complete turn-key solution for your most challenging motion and inspection applications.


Recent Ultra-Precision Projects:


Multi-Function Air Bearing Lathe/Grind MachineNuSTAR Optics Assembly Module

ABTech recently delivered the first of the custom multi-functional air bearing machines designed and manufactured for assembly of the X-ray optics-module for NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) project.

"The delivery went very smoothly and the machine is really an amazing piece of engineering craft. I hate to see your guys go. They were really great and patient with us."
- Marcela Stern - Research Staff at Columbia University Nevis Labs
