Air bearing bars
Precision Motion Using GraphAir™ Bearing Technology
OAV Air Bearing Bars deliver ultra-precise linear motion with zero friction, no wear, and exceptional stability.​
​
Through the use of our GraphAir™ technology, these systems create a uniform air film that eliminates mechanical contact and minimizes vibration. Ideal for semiconductor manufacturing, metrology, and automation. Available in multiple sizes for long-travel, high-rigidity applications.
