in a liquid Unlike some rolling element bearing supports that require periodic maintenance, cleaning, addition of oil lubricants and sometimes replacement or re-surfacing of guideways, the air bearing s self-cleaning nature allows it to be virtually maintenance-free Perhaps the most exclusive quality of gases as lubricants is their potential for being able to operate over an extremely wide range of temperatures In fact, it is the shortcomings of the solid components of the machine, not that of the lubricant, which will set performance limits when simple gases are used for high temperature lubricated applications No difficulty is foreseen, for example, at the hot end of the scale, in operating the bearings of small steam turbines Also, in gas bearings, a performance increase with a reduction in viscosity due to temperature increase is seen In the case of liquid bearings, the performance declines with a decrease in viscosity resulting from an increase in the temperature Externally pressurized bearings have been operated at temperatures of up to 900 C and at speeds of up to 65,000 rpm The advantages of aerostatic bearings can be summarized as follows: Low viscosity and hence low friction during shaft rotation Low power loss and cool operations due to low friction High rotational speed operations Precise axis definition and a high accuracy over a wide speed range Long life due to a virtually zero wear rate Low noise and vibration levels Virtually no necessity for periodic maintenance Ample and clean lubricant No necessity for oil or grease lubrication No contamination of surfaces by the lubricant Minimal contamination to the surrounding environment No necessity for a fluid-recovery system; these systems are clean Good performance of the lubricant at extremely low and extremely high temperatures The very-high-temperature operations feasible are limited only by the less capabilities of bearing and journal materials [5] No breaking down of the film due to cavitation or ventilation [9] Availability for both linear and rotary application Air bearings are more convenient compared to lubricated bearings as air has a fairly constant chemical composition with certain physical characteristics Compressed air is also often readily available in most factories for driving other machines The lubricant in an aerostatic bearing can be exhausted into the atmosphere without the need for recirculating equipments Air bearings are also relatively clean In order to take advantage of the superiority of aerostatic bearings, it is often necessary to take great care and pay attention to details This principal disadvantage is that it requires an external pressure source to create the air film In addition, for the same size bearing, the loadcarrying capacity of a gas-lubricated bearing is many times less than that of an oil-lubricated bearing The rest of the disadvantages are listed below: The surfaces must have an extremely fine finish The alignment must be extremely good

Dimensions and clearances must be extremely accurate The speed must be high The loading must be low Careful designing is required to avoid vibration due to compressibility of the fluid Careful filtering is required to avoid scoring and binding More power is required to pressurize a compressible fluid The design is more empirical since the flow relationships are almost impossible to solve A very small film thickness is required to confine the fluid flow to reasonable values, thus requiring very precise machining in manufacturing [5] The stability characteristics are poor [9] The poor stability characteristics are due to the compressibility of gases and the consequent delay between bearing clearance changes and the response to this change through variations in pressure in the orifice pocket This instability or pneumatic hammer is most often associated with thrust bearings In order to overcome this, the total pocket volume needs to be reduced by reducing the pocket depth and the diameter The second method is by using annular compensated orifices and sacrifices in a certain amount of load capacity [1] It is clear that the main limitation of the air bearing is the load capacity Aerostatic bearings are very sensitive to small variations in the clearance, and an overload condition must be avoided at all times Any touch down in an aerostatic bearing can be disastrous Therefore, it is often advised to have a generous safety margin and all applied loads shown below are considered [3]: Rotor weight Static and dynamic unbalance Applied cutting loads in machine tool spindles Electro-magnetic forces in motors Pressure forces on turbines or compressor wheels Transmission forces through a belt, coupling or gearing
