Motorized Integrated Dovetail
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.
