Radial Air Bearings


Radial Air Bearings

New Way Radial Air Bearings are ideal for precision rotary applications, giving you all the differential advantages of air bearings built on our proven Porous Media TechnologyTM.

Radial air bearings provide non-contact support for rotating, round artifacts using a thin (5µm) layer of air. This thin air layer is amazingly stiff, creating a stable support for a ring, or bearing surface, while allowing for surface speeds of up to 100 meters-per-second.

New Way radial air bearings can be configured to ride on the outer diameter or inner diameter of a rotating artifact for a given application, using concave and convex shapes using a radius cut along the length (L) or width (W) of the bearing, depending on your structural requirements. The bearings are specifically machined to the tight tolerances necessary to create non-contact motion.

The unique use of porous media in radial air bearings makes them ideal for clean room use. Not only is less air used in radial air bearings when compared to orifice-based air bearings, but the air is evenly distributed by the porous media. Both of these features minimize the potential of currents or eddies in the clean room and its damaging impacts on production.

Another benefit of the use of porous media is its ability to perform as a sub-micron filter for the air emitted. Testing indicates the bearing satisfies the requirements of Class 1 (ISO class 3) cleanliness, with airborne particulate concentrate limits of less than 1,000 x 0.1μm particles / m3.

While several standard sizes of radial air bearings are offered, New Way has more than 30 years experience developing custom solutions. Contact us to tell us more about your application!
