Present paper shows the results of numerical solution of laminar, unsteady lubricated cylindrical slide bearing. Laminar, unsteady oil flow is performed during periodic and unperiodic perturbations of bearing load or is caused by the changes of gap height in the time. Above perturbations occur during the starting and stopping of machine. The solutions apply to infinite length of lubricated Newtonian oil with dynamic viscosity depends on pressure. The disturbances related with unsteady velocity oils on the journal and on the sleeve. The results shown on diagrams of hydrodynamic pressure in dimensionless form in time intervals of displacement duration.
