New Way® Concave Porous Media™ Radial Air Bearings are designed to maximize open-ID aperture rotary motion. These made-to-order components enable you to engineer a supporting structure outside the rotating body using a radius cut along the width (W) of the bearing. As with all New Way non-contacting air bearings, radial designs offer the benefits of no friction, no noise, no wear, excellent velocity control and high speed. Ideal for high-performance rotary motion operations, New Way Radial Air Bearings offer precision performance in inspection, imaging, wind power, turbomachinery, wafer inspection machinery, powder processing and applications requiring very large rotary bearings.
