This research work is part of a broader comprehensive issue, which is the analysis of flow and operating
parameters of journal slide bearings lubricated with ferro-oil. In this article, the author presents only the main
assumptions and essential transformations of the analytical and numerical model for determining the pressure
distributions in the gap of a slide journal bearing lubricated with ferro-oil. It is cardinal that the rheological and
magnetic values of ferro-oil parameters adopted in numerical calculations are based on the results of actual values
obtained in the author’s earlier research work. There are presented the pressure distributions by abovementioned
method in the article for cases of bearings lubricated with ferro-oils with different concentration of magnetic
particles. The obtained results are shown in the form of a set of four complementary characteristics of the
dimensionless pressure distributions. First and main of them are the calculations for classical Newtonian lubrication
but they take into account the influence of the magnetic field on the distributions. The next of the presented
characteristics are so-called "corrections" of pressure distribution values, taking into account as follows: effects of
changes in ferro-oil viscosity related to temperature changes, impacts of ferro-oil viscosity changes related to
pressure changes and the effect of non-oil properties of the lubricant. The article includes a qualitative and
quantitative analysis of the obtained results as well as observations and conclusions are presented in it.
