Radial Air Bearings Concave L Profile

 

Radial Air Bearings Concave L Profile

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 Technology™.

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. Our concave L radial air bearings are configured to ride along the outer diameter (OD) of your rotating artifact with a cut radiused along the length of the bearing.

Cleanroom Compliance

The unique use of Porous Media Technology™ in radial air bearings makes them ideal for cleanroom 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 cleanroom, 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!
