pre-integrated linear guides
OAV’s Pre-Integrated Motorized Linear Guides combine frictionless linear air bearing guides with precision motorized drive systems to deliver turnkey motion platforms for the most demanding ultra-precision applications. This product family is engineered for customers who require exceptional straightness, smoothness, stiffness, and repeatability—without the complexity of designing and integrating individual motion components.
Each system is built around OAV’s proven linear air bearing technology, utilizing porous graphite bearing surfaces and advanced air distribution to achieve true non-contact motion. When paired with vacuum preloading, the carriage is actively constrained to the guide while remaining completely lifted from the surface, resulting in zero mechanical wear, zero backlash, and elimination of stick-slip effects.
The motorized drive components are fully integrated and factory-aligned, ensuring optimal performance out of the box. These solutions reduce integration time, minimize alignment errors, and provide a compact, clean, and maintenance-free alternative to conventional mechanical linear guides. When combined with high-resolution feedback and motion control, OAV’s motorized air bearing systems enable nanometer-level positioning and exceptionally smooth velocity profiles.
OAV’s Pre-Integrated Motorized Linear Guides are ideal for precision positioning, scanning, inspection, and measurement systems across optics, semiconductor manufacturing, metrology, aerospace, and advanced research environments. Available in multiple sizes, travel lengths, and configurations, these systems can be customized to meet specific load, speed, and accuracy requirements.
