The flat rectangular air bearing stands alongside the flat round air bearing as one of our original New Way® products, and this product line is still going strong today. By employing our foundational Porous Media technology™, the flat rectangular air bearing moves across the guide surface on a 5 micrometer, thin layer of air and enables truly Frictionless Motion®️®.
The natural permeability of carbon provides a more even distribution of air, offering superior performance unavailable to conventional- and orifice-based bearings.
Since the bearings don’t need to contend with friction, flat rectangular air bearings achieve high speeds and rapid acceleration. This allows precision systems to achieve ultra-high resolution, with no hysteresis error. This unique property makes them ideal for pick-and-place machines in such fields as the semiconductor manufacturing sector, as well as for XY-gantry configuration in checkmate coordinate measuring (CMM) machines, and 3D printers.
Furthermore, the designs are inherently more crash resistant than orifice bearings, since the air is slowly diffused by the Porous Media™. In case of an air supply loss, the bearing slowly comes to rest on its guide surface, minimizing damage. When we stop to consider that porous media air bearings don’t require lubrication which the regular maintenance lubricated bearings often require, operational efficiencies are greatly improved.
New Way Flat Rectangular Air Bearings are designed to carry high loads while maximizing the load-bearing surface for the guide through a gimballed mounting system. These bearings can be mounted on ball mounts, providing a self-leveling interface between the bearing and the guide surface.

Porous media’s unique structure also makes flat rectangular air bearings a perfect fit for industries that require clean room compliance. Because air bearings don’t use lubricant (thus no outgassing) and because porous media acts as a natural sub-micron filter, all New Way Air Bearings are ISO class 3 cleanroom compliant, and according to internal New Way testing, even meet the incredibly stringent requirements for ISO Class 1.
All flat rectangular air bearings are available in metric and US sizing off the shelf, and we’re happy to design and manufacture custom sizes per your specifications!
New Way Flat Rectangular Air Bearings are ideal across a diverse set of applications. All of these industries and processes share a need for exacting precision and efficient operation.
With the success of the flat, round porous media air bearing product line, we added the rectangular configuration offer an integration alternative. For some linear motion applications, the rectangular profile provides a more efficient bearing surface alignment.
