Air bearing is a new type of bearing which uses the elastic potential energy of air as support. The only lubricant used is air; Therefore, air bearing technology is ideal for the workpiece or working environment that must be pollution-free.

 

 

 

In air bearings, the ball is replaced by an air cushion. One of the best-known applications of air bearings is perhaps the hovercraft. Huge fans blow air under the hovercraft, preventing it from escaping through elastic rubber "skirts". The high air pressure created underneath the hovercraft supports the weight of the hull, thus allowing it to float on the air cushion.

 

 

 

Since the 1950s, gas bearings have been more and more widely used, and have been widely and deeply studied. At present, gas bearings can be used in textile machinery, cable machinery, instrument machine tools, gyroscopes, high-speed centrifuges, dental drills, cryogenic refrigeration machines, hydrogen expanders and high-temperature gas circulators, etc
