Abstract An endeavor has been made to analyze the performance of an infinitely long magnetic fluid based hydrodynamic slider bearing in the presence of a magnetic fluid lubricant. The associated Reynolds' equation is solved with appropriate boundary conditions. Expressions for dimensionless pressure, load carrying capacity and friction are obtained. Computed values are displayed graphically. It is seen that the magnetic fluid lubricant improves the performance of the bearing system. The friction decreases at the moving plate while it increases nominally at the fixed plate due to magnetization. In order to extend the life period of this magnetic fluid based bearing system the outlet film thickness ratio plays a better role as compared to that of the aspect ratio.
