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 length (L) or width (W) of the bearing, depending on structural requirements. Offering the benefits of high-speed, high-precision, no friction, no wear, and excellent velocity control, these porous media air bearings are ideal for a wide range of high-performance and very large rotary bearing applications such as inspection, imaging, wind power, turbo machinery, powder processing, and wafer inspection.
