Gas /Air Lubrication-Bearings
Lubrication is fundamental to the operation of all engineering machines. It is required
to minimise friction, wear and also provides a cooling function and a surface protection
Gas lubricated bearings have numerous advantanges over liquid and solid lubricated bearings for a wide
range of applications. A gas bearing is virtually frictionless, silent,
and vibrationfree. Gas bearings can be used for extremely large surface velocities. A gas bearing
can eliminate the risk of contaminating a process with lubricant.
A gas / air bearing can be hydrodynamic or hydrostatic. In hydrodynamic bearings
the gas is introduced into the bearing surfaces by the action of the bearing. In hydrostatic
bearing the gas is introduced under pressure from an external source.
Air bearings are also widely used to allow frictionless movement of large heavy items
over flat surfaces using air pads.
