The DOV150150-M100 is the motorized evolution of the Dovetail-Series, combining OAV’s precision dovetail linear air bearing guides with a fully integrated drive system for turnkey ultra-precision motion. Engineered for applications requiring smooth, vibration-free, and maintenance-free linear movement, this system delivers nanometer-level positioning with reliable repeatability.

Manufactured from premium aircraft-grade materials, the Dovetail-Series guide features a porous graphite air bearing surface that ensures uniform air distribution and optimal stiffness. The vacuum-preloaded design locks the carriage in place while maintaining non-contact operation, providing ultimate accuracy and eliminating stick-slip or mechanical wear.

The integrated motorized drive is factory-aligned with the guide, creating a plug-and-play solution that simplifies installation and reduces integration time. Like its non-motorized counterpart, the system includes a pre-tensioned brake function for stable positioning under load, now combined with precise, controllable motion via the motor.

150 mm × 150 mm travel platform with vacuum-preloaded carriage

Frictionless, non-contact motion with zero wear and zero stick-slip

Factory-aligned drive for plug-and-play installation

Pre-tensioned brake function for stable positioning under load

Porous graphite bearing surface for uniform stiffness and vibration damping

Ideal for precision positioning, scanning, metrology, and research applications

The OAV Motorized Integrated T-Series Motion Solution combines OAV’s ultra-precision vacuum-preloaded linear air bearing technology with a fully integrated drive system to deliver a turnkey, frictionless motion platform. Designed for demanding metrology, optics, semiconductor, and research applications, this solution provides exceptional straightness, repeatability, and smoothness without mechanical contact.

Manufactured from premium aircraft-grade materials, the T-Series rail guide utilizes a porous graphite air bearing surface that simultaneously applies positive air pressure and vacuum preload. This dual-force design actively lifts the carriage while rigidly holding it down to the guide surface, achieving superior stiffness, stability, and vibration damping compared to conventional air bearing systems.

The integrated motor and drive components are precision-aligned at the factory, eliminating the need for complex customer integration while ensuring optimal performance. The result is a compact, clean, and maintenance-free linear motion solution capable of nanometer-level positioning when paired with appropriate feedback and control electronics.

The DOV150150-MXXX-2C is the motorized evolution of the Dovetail-Series, combining precision dovetail linear air bearing guides with a fully integrated drive system for turnkey ultra-precision motion. Configured with dual, independently motorized air bearing carriages, each equipped with its own dedicated encoder, the system is engineered for applications requiring smooth, vibration-free, and maintenance-free linear movement, delivering nanometer-level positioning with reliable repeatability and advanced motion control.
Manufactured from premium aircraft-grade materials, the Dovetail-Series guide features a porous graphite air bearing surface that ensures uniform air distribution and optimal stiffness. The dual-carriage, vacuum-preloaded architecture maintains non-contact operation while increasing rigidity and moment load capacity, providing exceptional accuracy and eliminating stick-slip or mechanical wear.
Each carriage incorporates a factory-aligned motor and encoder, enabling synchronized or independent motion profiles within a single platform. This plug-and-play configuration simplifies installation, reduces integration time, and expands system flexibility. The rail platform length is fully customizable to support a wide range of travel requirements. Like its non-motorized counterpart, the system includes a pre-tensioned brake function on each carriage for stable positioning under load, now combined with precise, controllable motion through the integrated drive system.
