An air bearing is a device, usually made from a rubber-type fabric, that is designed to inflate with compressed air and forms a floating action above the floor surface it is sitting on.
Incorporated into an air caster load module, the air bearing is then used, with others in a series of three or more, to simultaneously float heavy loads away from the floor surface on a thin film of air thus allowing the loads to be floated - similar to a hovercraft - to a new destination.

Air bearings are designed to lift loads away from the floor surface and float them off to their destination on a thin film of air. Each individual air bearing is housed in a load module which contains an air flow control valve to regulate the operation of that air bearing.
When compressed air is introduced into the air bearing, the bearing initially inflates to form a seal between the bearing and the floor surface. As the air bearing is further pressurized it is forced to expel compressed air from the exhaust holes in the air bearing diaphragm. The force of this expelled air against the floor surface causes the air bearing and load module to lift off the floor on a thin film of air. The load should now be in flotation mode and ready for action.

Air bearings need to be coupled with other air bearings, in sets of three or more, to form a system that can handle an appropriate load. An individual air bearing is not able to balance a load on its own - it will tip easily - nor is it capable of being adjusted to accommodate variations in load weight and irregular shape. The strength of air bearing lifting power becomes apparent when they are grouped together and their collective lifting abilities are combined to offer some formidable lifting capacities.
When air bearings are grouped together to form an air bearing system, they then offer some real lifting power. The beauty of using air bearings in groups of three or more is that they can be individually adjusted to suit the properties of the load they are carrying.
