Rayleigh step bearing
WebDec 5, 2013 · It has a history of about 100 years that Rayleigh step bearing can give optimum load-carrying capacity for certain geometry. As to parallel bearing, several mechanisms have been proposed: the thermal wedge, the viscosity wedge, the thermal distortion, and the local hydrodynamic effect induced by surface irregularities.
