Linear Air Bearings Industry Information

Linear Air Bearings

Linear air bearings have very high accuracy and can run at full speed without fatigue or wear. They move the load in one dimension and can be combined for multi-axis positioning. Flat pad air bearings are shaped like hockey pucks, while others are of varying height, diameter, and shape. Bearings are made from hardcoat aluminum, stainless steel, steel, granite, ceramic, bronze, or carbon and are typically found in a rectangular housing of similar materials, mounted on a track for fast, smooth, and precise motion.

Linear Air Bearing Applications

Useful in a variety of applications, linear air bearings are found in the manufacturing, medical, research, chemical, and engineering industries for precise assembly, force measurement, calibration, semiconductor pick-and-place machinery, zero-gravity simulators, scanning, and more. Because they are free of oils or lubricants and rely on pressurized air, they are suitable for use in cleanrooms.

How Linear Air Bearings Work

In order for fluid film bearings to work, they must have a source of pressurized air, though nitrogen can also be used. Hydrostatic bearings use an external pressurized supply, while hydrodynamic bearings use the motion of the machine's components to self-generate internal pressure. Typical bearings are hydrostatic and use simple compressed air to operate. The two main kinds of air bearings—porous and orifice—refer to how pressurized air enters the bearing. Air penetrates through millions of tiny holes in the media of a porous bearing, while an orifice bearing has a small hole a fraction of an inch in diameter that air flows through. As air is steadily fed to the bearing, a layer only microns thick forms around the bearing, separating it from the surface and allowing the housing to glide smoothly and precisely. Computers or machine operators control the machine's movements; air bearings do not lose accuracy or shape and therefore only need to be calibrated once. Because they are frictionless, air bearings cannot overheat and will not warp or wear; they also do not need to warm up before the desired range of motion is achieved. Manufacturers do recommend that the bearings are used in an environment that is at room temperature, so the housing does not distort and disturb the layer of air around the bearing.
