Air Bearings
Air bearings are a type of fluid bearing that utilizes a thin film or pressurized air in place of solid rolling elements to provide low-friction load bearing in which the two internal surfaces do not touch. The result is a bearing that has zero static friction, zero running friction, and high stiffness. To achieve this degree of stiffness, air bearings must be preloaded through the application of weight, vacuum, magnetic attraction, or an opposing air bearing.
Due to these characteristics, most air bearings require little or no maintenance and have almost unlimited life, especially when compared to rolling element bearings that have higher viscosity, and thus, higher wear. They are also ideal for precision positioning and high speed applications since their contact-less operation eliminates backlash and static friction.

IBS Precision Engineering
IBS Precision Engineering offers the porous New Way Air Bearings. The porous material ensures equal air distribution under the bearing. Porous air bearings exceed orifice bearings as far as bearing capacity, rigidity and air consumption go. Because of zero static friction, infinite resolution and very high repeatability are possible.Tagged: bearing -
Isotech
Isotech offers AB Air Bearings that feature a specially shaped stainless steel piston precisely fitted to a borosilicate glass cylinder. This create a true air bearing airflow effect around the piston. As little as 5 psi applied to the cylinder produces a stiff cushion of air that supports the piston and prevents it from coming in contact with the cylinder wall. The AB Air Bearing provides virtually unlimited piston life, super-clean operation, requires no lubrication, and nearly eliminates friction through the use of ultra-low friction ball joints used to connect the rod.HatfieldState: PATagged: cylinder -
