Abstract :Abstract This paper presents numerical solution to the pressure distribution of a fluid in a hydrodynamically lubricated journal bearing using the classical Reynolds equation that models the effect of side or end leakage i.e., there is flow in the z-direction in bearings. The finite element method was used to analyze the flow. Two dimensional interpolation functions were used in the modelling and discretization of the domain of analysis. The result obtained from this research shows that the pressure increases from the ambient pressure which is taken to be zero at an angular displacement of   and increases significantly till   . At this point, the pressure becomes maximum. Thereafter, it begins to drop until it gets to   where the pressure becomes the same as the ambient pressure. From this point onward, we begin to experience negative pressure. The negative pressures in this regard are those that are below the ambient pressure.
