The problem is mathematical modelling of oil film bearing at the rotary system. The new access comes from Navier-Stokes equation of fluid, supported by equation of continuity and Bezier's body. In this article is note the solution of mathematical model of fluid film bearing by perpendicular and especially by non-dimensional coordinates. There was inserted modelling problem in this article, in which we are modelling the trajectory of centre of the shaft under fluid film bearing, where the count have been carried by non-dimensional coordinates.
