How Does An Air Bearing Work?

What are air bearings used for?

Air bearings (also known as aerostatic or aerodynamic bearings) are fluid bearings that use a thin film of pressurized gas to provide a low friction load-bearing interface between surfaces..

What is gas lubrication?

Gas lubrication is the process of removing gas from beneath the BOP stack while maintaining constant bottom hole pressure. Lubrication is best suited for surface stacks, but the dynamic gas lubrication procedure can be used to vent gas from beneath a subsea stack.

How do magnetic bearings work?

Magnetic bearings rely on levitation that is the process by which an object is held aloft without mechanical support. The supporting forces can originate from several sources, however, when they are produced by the magnetic field the process is referred to as magnetic levitation.

How do air foil bearings work?

Foil air bearings are self-acting hydrodynamic bearings that use ambient air as the lubricant instead of oil. Both air and oil are fluids that can perform the job of separating moving metal parts. The very high rotational speeds of turbine engine shafts (>10000 rpm) allow the replacement of oil with air.

What is gas bearing?

Gas bearings allow the shaft to rotate on a thin layer of ambient air where friction is low and no external delivery system is needed (Larjola, 1988). From: Small and Micro Combined Heat and Power (CHP) Systems, 2011.

How do air casters work?

An air caster is a pneumatic lifting device used to move heavy loads on flat, non-porous surfaces. Its operation is similar to a hovercraft, as it uses a thin layer of air as a way to float a very small distance off the ground.

What is the best lubricant to use?

What are types of lubricants?

There are 4 types of lubricants: Oil, Grease, Penetrating Lubricants, and Dry Lubricants.

What are some examples of lubricants?

Common examples of internal lubricants include fatty alcohols, esters (low esterification), and EVA wax. External lubricants provide metal release and help reduce process temperature. Common examples of external lubricants include PE waxes, paraffin, metal soaps, esters (high esterification), amides, and fatty acids.
