Due to their advantageous characteristics, gas-lubricated bearings are increasingly being adopted in various oil-free applications. These bearings utilize a gas lubricant that is directly sourced from the working fluid of the rotating machine. Furthermore, self-acting bearings eliminate the need for an external supply system or compressor, allowing for the development of compact and hermetically sealed systems. The low viscosity of gaseous lubricants also helps minimize frictional losses, thereby enhancing the overall efficiency of rotating machinery. Another key advantage of gaseous lubricants is their stable physical and chemical properties, as they do not undergo vaporization, cavitation, decomposition, or solidification across a broad temperature range.
