Motorized rotary Air Bearings STAGES
Motorized Rotary Air Bearing Stages for Ultra-Precise Motion Control
OAV Motorized Rotary Air Bearing Stages combine precision GraphAir™ bearing technology with an integrated direct-drive motor to deliver frictionless rotary motion with sub-micron accuracy. By eliminating mechanical contact, these systems provide exceptional smoothness, zero wear, and ultra-stable performance in demanding high-speed and high-precision applications.
Designed for seamless integration, each stage features a compact, through-bore architecture and plug-and-play connectivity with optional servo control (M23 ready). The integrated BLDC motor delivers high torque, rapid acceleration, and precise position control, supported by encoder feedback for real-time closed-loop performance.
Constructed from aerospace-grade materials, OAV motorized rotary stages offer high stiffness, thermal stability, and cleanroom-ready operation. Their maintenance-free design ensures long service life while maintaining consistent accuracy across a wide range of speeds and load conditions.
