Bullet Points:
  • Vacuum preloaded air bearings are the ideal solution for applications where mechanical preload is difficult to accomplish
  • Using a combination of air pressure and vacuum its possible to optimise the fly height and stiffness depending on the needs of the application
  • Vacuum preloaded air bearings are available in standard sizes of 50mm, 80mm & 100mm
  • Custom designed vacuum preloaded air bearings are also possible

The OAV Vacuum Preloaded Air Bearing works on flat, nonporous surfaces such as granite, aluminum, glass, and ceramics. Its round design allows for smooth, frictionless motion. We offer a variety of sizes that can easily be used for custom air bearing systems. The OAV Vacuum Preloaded Air Bearing combines the use of air pressure and a vacuum to allow for the air bearing to be held down while simultaneously being lifting from surface.

Data Sheets:
  • Modular Corner Air Bearing, //images/images/products/data-sheets/Modular_Air_Bearings/OAV90DEG50-BSC.pdf
Bullet Points:
  • Modular Air Bearing design.
  • Subdivides motion system into smaller install-able parts.
  • OAV modular air bearing can be independently install and then used in different systems and different shapes
  • Benefits can include reduction in cost, shorter installation time, flexibility in design, augmentation and exclusion

The OAV Modular Air Bearing design subdivides motion systems into smaller installable parts. They can be independently installed and then used in different systems and shapes. OAV Modular Air Bearings make use of industry standards for interfaces. 

OAV Modular Air Bearings offer many benefits such as reduction in cost, shorter installation time, flexibility in design, augmentation, and exclusion. It is a complete offering of air bearings produced with the design for easy retrofitting into existing applications or designing into new applications for ultimate accuracy positioning.

OAV Air Bearings generate evenly distributed gas films between surface and the substrate. Because of low gas viscosity and friction losses by viscous shearing, mechanical contact is avoided. Our modular air bearings are manufactured from aircraft quality lightweight material. It is ultra-precise with exceptional linear straightness and flatness. Vibration and maintenance-free, ready to install.

Data Sheets:
  • Thrust Air Bearing Design & Installation Guide, //images/images/products/data-sheets/Thrust_Air_Bearing_Design_and_installation_guide.pdf

The OAV Thrust Air Bearing is a breakthrough innovation in air bearing technology. For the first time, an air bearing is available that fully integrates and works on a three-way frictionless surface. The OAV Thrust Air Bearing configurations run on standard sized shafting for fixed, linear motion while maximizing rotational motion with ultra precision and zero friction using aerospace quality aluminum.

OAV Air Bearings have higher stiffness and excellent geometric performance. The OAV Thrust Air Bearing preloads both the horizontal and vertical surfaces with opposing thin films of pressure. This maintains the perfect gap for ultimate tolerance, and the surface design of the bearing equally distributes the air and pre-loads it over the entire surface area. The result is outstanding stiffness with maximized performance.
