Modular Air Bearings

Modular Air Bearings for Flexible System Integration

OAV Modular Air Bearings are designed to simplify precision motion system integration by dividing bearing functionality into compact, installable components. Each module can be independently configured and combined, allowing engineers to build custom motion systems with greater flexibility and efficiency.

Using our advanced GraphAir™ film technology, these bearings create a uniform, non-contact interface that eliminates mechanical wear while maintaining high stiffness and accuracy. The modular architecture reduces installation time, lowers system cost, and enables easy retrofitting into existing designs or rapid integration into new applications.

Engineered for high-precision positioning, OAV modular air bearings deliver exceptional straightness, flatness, and repeatability across demanding environments. Their scalable design supports a wide range of configurations while maintaining clean, maintenance-free operation and long-term reliability.

Typical Applications

Precision automation systems
Semiconductor manufacturing equipment
Optical alignment and metrology systems
