Why choose OAV Air Bearings?
Frictionless motion
A pressurized air film eliminates mechanical contact for zero friction and zero wear.
GraphAir porous graphite
Porous carbon distributes air uniformly for stable, repeatable sub-micron positioning.
Quality certified
Products are ISO 9001:2015 and AS9100 Rev D certified with RoHS/REACH compliance.
Global reach
Over 60 years of experience serving more than 100 countries from Princeton, New Jersey.
Product series
Understand each series to find the right fit for your application.
Flat Round Air Bearings
Round porous-graphite pads that float on flat granite, glass, or ceramic for frictionless motion in sizes 25-200 mm.
Air Bushings (Journal Bearings)
Externally pressurized bushings that guide standard shafts with zero contact and high stiffness, bores 6-90 mm.
Vacuum Preloaded Air Bearings
Bearings combining positive air pressure with vacuum preload on a single flat surface for higher stiffness and damping.
Flat Rectangular Air Bearings
Rectangular porous-graphite pads delivering uniform load distribution and sub-micron planar positioning.
