x-Spin Rotary Air Bearing

Ultra-Precise Rotary Motion with Advanced Air Bearing Architecture

Outer ring spin OAV frictionless rotary air bearing

The OAV X-Spin Rotary Air Bearing introduces an advanced roller-based air bearing architecture engineered to deliver superior stiffness, stability, and rotational accuracy. Designed for ultra-precision applications, this system enables smooth, high-speed rotation with runout performance measured in fractions of a micron.

Utilizing porous graphite air film technology, the X-Spin operates with true non-contact motion—eliminating friction, wear, and heat generation. Pressurized air is evenly distributed across the bearing interface, maintaining a stable, controlled gap that ensures consistent preload and exceptional geometric accuracy during operation.
