New Way® Convex Porous Media™ Radial Air Bearings are designed to minimize the OD circumference. These made-to-order components enabling you to engineer a supporting structure inside the rotating body using an external radius cut along the length (L) or width (W) of the bearing, depending on your requirements. Based on New Way proprietary porous media technology, these radial air bearings offer the benefits of high speed, infinite resolution, sub-nanometer repeatability and high stiffness while operating without friction, noise, lubrication and wear. Ideal for very large rotary bearing applications, New Way Radial Air Bearings address the high-performance requirements of turbomachinery, wafer inspection machinery, imaging and others.
