What is an Air Bearing?
An air bearing is a non-contact, frictionless bearing system that uses a thin layer of pressurized gas (mostly air). The air acts as the lubricant, creating an evenly distributed gas film between the surface and the substrate. The result - no friction, no maintenance, ultra-precision, and clean motion with higher stiffness.
Why you should consider Air Bearings
OAV Air-bearing technology generates evenly distributed gas film between the surface and the substrate. Due to low gas viscosity, there is no friction losses by viscous shearing, any mechanical contact is avoided, there is no contact between the surface, and no slip-stick phenomenon.
Air bearings coefficient of friction is a function of air shear from motion, not from surface contact. Therefore at zero velocity, there would be zero friction thus making infinite motion resolution theoretically possible.
Zero Friction-indefinite operating life, However, we use the coefficient of friction .00008 in log-scale due to the contribution from air molecules and gravitation.
Contaminant-free, clean environments generate virtually no particulates that can become airborne. Ideal for many
No heat generation at high speed
Excellent accuracy, nano-precision, and repeatability
