Vacuum Pre-loaded Air Bearings

OAV Vacuum Preloaded Air Bearings work on flat, nonporous surfaces such as granite, aluminum, glass, and ceramics. The round design allows for smooth, frictionless (no contact) motion. We offer a variety of sizes easily adapted for custom preloaded air bearings. OAV Vacuum Preloaded Air Bearings combine the use of vacuum and air pressure, creating superior damping. It allows the air bearing to press down while simultaneously being lifted from the surface.

By combining vacuum and air pressure, these bearings offer advantages for many applications across various industries. The vacuum preloaded air bearings can be optimized by adjusting the vacuum and pressure separately, allowing precise control over the fly height and stiffness.

The vacuum preloaded line replaces part of the bearing's surface area with a dedicated vacuum pressure zone. Fine-tuning of this vacuum/pressure setup achieves superior damping, resulting in the need for only one flat guide surface rather than two.
