Do you know thin section bearing?

Elastic sheet gas dynamic pressure bearings (Thin section bearing) are more and more widely used in aerospace and civil high-speed machinery (such as gas turbochargers, high-speed centrifuges, oxygen generators, air-jet spinning) because of their high-speed dynamic performance. Yarn machine, liquid rocket propulsion system, rail transporter) and other fields. Their uniqueness lies in their outstanding performance, despite the weight and space constraints. Minimal, the usual square cross-section allows high precision of the mechanism.
