New Way® Air Bushings are ideal for rotary or linear shaft-based applications and are most often found where precision motion is required concurrently. Offered as an alternative to ball bearings, New Way Air Bushings remove friction through the use of our foundational Porous Media TechnologyTM.
Air bushings distribute air through a ‘tube’ of porous media containing millions of sub-micron holes. The natural permeability of the porous carbon provides an even distribution of a thin, but a stiff layer of air. The design elicits a self-centering force allowing a full 360°non-contact motion on round shafts.
Retrofits with ball bearings are easily achieved by coupling the air bushing with a pillow block housing unit. Co-polymer O-rings are provided for ease of installation into the pillow block to compensate for parallelism errors of up to .002″ over the length of the shaft.

The unique use of porous media in air bushings makes them ideal for clean room use. Not only is less air used in air bushings 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.
Looking to constrain one end axially? New Way also offers a thrust bushing as a natural extension of the air bushing.
With friction removed, New Way Air Bushings offer a number of operational efficiencies available across industries. Several example industries and the benefits they are seeing are listed here. Feel free to contact us today directly for use in your application!
