Flat Rectangular Air Bearings
New Way® Flat Rectangular Air Bearings offer a non-contact bearing solution for use in linear applications. By employing our foundational Porous Media Technology™, a thin and stiff layer of air is distributed across a carbon face, removing friction. The natural permeability of carbon provides an even distribution of air offering superior performance unavailable to conventional and orifice-based bearings.
With friction removed, New Way Flat Rectangular Air Bearings are capable of maintaining high speeds and accelerations with impressive fly-height accuracies to deliver nano-level precision. The design itself is inherently crash-resistant as the air is slowly diffused by the porous media in the event of air supply loss, minimizing the chance of surface damage. All of this, coupled with the removal of burdensome oil-based lubrication requirements, greatly improves operational efficiencies.
New Way Flat Rectangular Air Bearings are designed to carry high loads, while also maximizing the bearing surface area for the guide. The design includes a gimballed mount making them easy to integrate or change. The gimbaled mount enables a simple method for alignment and configuration changes, as well as the flexibility to fine-tune as needed.
Available in several standard off-the-shelf sizes as well as custom sizes, New Way enables you to create a linear stage for your unique application. Contact us today to get started!
Flat Rectangular Air Bearing Product Line
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.

Applications
New Way Flat Rectangular Air Bearings are ideal across a diverse set of applications. Regardless of their use, what they share in common is the need for high-precision and efficient operations.
- Flat rectangular air bearings had their beginnings in the CMM industry because of the superior precision, without fear of damage in an air loss scenario
- With friction removed, results are repeatable, improving confidence in measurements where high-precision is crucial
- Flat rectangular air bearings are ideal for accurate linear positioning to achieve printing/cutting with superfine resolution
- With the removal of lubrication requirements, operational production increases as maintenance downtime disappears
- Useful in testing operations for acceleration performance and frame integrity, flat rectangular air bearings contribute no additional error, providing an honest assessment of critical safety features
- The non-contact nature allows isolation of the true source of noise/vibration, an improvement over conventional bearings which often mask such issues.
- Operations improve in both quantity and quality with the ability to deliver nano-precision wafers at high-speeds, without fear of damage in the event of air supply failure
- The non-contact nature not only meets clean room compliance, but also greatly reduces maintenance costs as the need for lubrication and parts replacement become obsolete
