The disadvantages of gas-lubricated bearings

1, low carrying capacity

Compared with similar oil-lubricated bearings, the bearing capacity of gas-lubricated bearings is about 1 to 2 orders of magnitude lower. According to the bearing capacity per unit area, oil-lubricated bearings are generally (0.5 to 2) MPa, while gas-lubricated bearings are only (0.02 to 0.04) MPa.

2, poor reliability

On the one hand, gas-lubricated bearings are prone to destabilization. Commonly there are air hammer vibrations and eddy-action instability. On the other hand, gas-lubricated bearings have stuck, hold shafts, or snapping.

3, the need for high precision manufacturing, costly

Because the gas film is very thin, generally between a few micrometers and tens of micrometers, so the requirements for the precision of parts manufacturing are higher, and the cost is increased. In addition, there are special processing requirements such as processing spiral grooves, throttling orifices, and porous materials, which increases manufacturing difficulty and costs.

4, demanding working conditions

Gas-lubricated bearings require a clean working environment and strict adherence to operating procedures to ensure that the bearings work properly without accidents. To this end, it has limited its wide application and commercialization.
