A hybrid (hydrostatic and hydrodynamic) model applicable to thrust bearing and hydraulic machine port plate is presented here. The model is based on Reynolds equation and variable viscosity effect is considered. Assumptions made are listed. Regardless of the assumptions, the model agrees with experimental results and can be used with minor restrictions for new hydraulic machines' and bearing design. Balance factor as a function of speed of rotation, gap height, barrel inclination and fluid viscosity is presented. The variable viscosity effect makes analysis more accurate for certain conditions when port plates' failures are likely.
