This article goals to determine the enactment of double layered porous rough conical plates with ferrofluid based squeeze film lubrication. The Neuringer–Roseinweig model has been employed for magnetic fluid flow. For the characterization of roughness two different forms of polynomial distribution function have been used and comparison is made between both roughness structure. The stochastic model of Christensen and Tonder regarding transverse roughness has been invoked to develop the associated Reynolds’ equation from which the pressure circulation is found. This provides growth to the calculation of load-bearing capacity. From the graphical appearance it is established that from the design point of view roughness pattern G1 is more suitable compared to G2. The results presented here confirm that the introduction of double layered plates results in improved load carrying capacity. This is further enhanced by the ferrofluid lubrication. Further, the roughness affects the bearing system significantly, however, the situation enhanced in the case of negatively skewed roughness. A noticeable fact is that the porosity of the outer layer influences more as compared to the inner layer even in the presence of mild magnetic strength.
