OPen PilLow BLock Air Bearings

OAV Open Pillow Block Air Bearings are designed for precision linear motion systems requiring increased rigidity and stability over extended travel distances. By combining a supported shaft design with advanced porous graphite air bearing technology, these units provide superior alignment, reduced deflection, and consistent motion performance.
​
Unlike traditional unsupported shaft systems, the integrated rail support structure improves straightness and load handling while maintaining a uniform, non-contact air film. This eliminates friction, wear, and lubrication requirements, resulting in smooth, maintenance-free operation and long service life.
​
Engineered for high-precision applications, OAV pillow block air bearings deliver excellent straightness, repeatability, and stability across longer spans. Their robust design makes them ideal for systems where accuracy, rigidity, and reliability are critical.
