Bearings - Advantages of foil bearings - Unlike traditional pressurized hydrostatic bearings, foil bearings use hydrodynamic action of the fluid to support shafts in rotating machines. At standstill, the shafts are held by a journal lining made of spring-loaded foils. When the shaft starts spinning, the working fluid creates hydrodynamic pressure which lifts the foil from the shaft so there is no contact.
