This paper deals with calculation of static equilibrium position of finite length hydrodynamic journal bearings. Cylindrical and lemon bore hydrodynamic bearings are considered. Investigating the static equilibrium position of the journal is very important for the correct determination of static and dynamic characteristics of the bearings. The solution to this problem depends on the hydrodynamic pressure in the bearing. The numerical solution of the Reynolds equation is used to calculate the pressure. The effect of variable viscosity and density of the lubricant due to temperature changes is considered. The results of static equilibrium position are shown for specific lemon bore bearing.
