New Way® Metric Air Bushings are designed for rotary or linear metric shaft-based applications. Built on our foundational Porous Media TechnologyTM, New Way Metric Air Bushings remove friction in the form of a ‘tube’ of porous media. This permeable surface naturally distributes an even, yet stiff, layer of air, to provide the necessary lift/gap for operation.
This unique method of removing friction offers enhanced precision unavailable to rolling element systems, making them ideal for applications requiring precision rotary and linear motion concurrently. Maintenance downtime is also significantly reduced as burdensome lubrication requirements become obsolete. These advantages make New Way Metric Air Bushings a win-win for operations!
Air bushings can be paired with a pillow block housing unit for a simple interchange with existing rolling element systems. 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.

New Way Metric Air Bushings are offered in six standard metric sizes to accommodate standard metric precision steel shafts. Custom sizes are also available.
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.
