The dynamic pressure air bearing operates by creating a gas film between the shaft and the bearing, which generates pressure in the convergence area of the sliding surfaces.
During the formation of a pressurized gas film, as the speed increase, boundary friction, mixed friction, and fluid friction occur sequentially in the bearing area. When a specific rotational speed is reached, the air pressure field casued the shaft to suspend and provide lubrication. Due to the low viscosity of gas, air bearings have almost no friction and energy loss. This characteristic can significantly enhance the effciency and ligespan of the system.
