The application of textured surfaces on tribo-pairs has emerged as a new technique to improve their performance [1-2]. At the same time, electrorheological (ER) lubricants are a novel type of smart lubricants with controllable rheological properties [3-4]. The present paper investigates the combined effect of textured surfaces and ER lubricant on hybrid spherical journal bearing. Within the scope of this study, spherical dimples have been applied on the bearing surface and the influence of different values of applied voltages has been studied. A finite element method approach has been used to solve the modified Reynolds equation by incorporating suitable boundary conditions [5]. The static and dynamic performance parameters of hybrid spherical journal bearings have been numerically computed. Numerical results show that different values of applied voltages significantly alter the bearing performance and that the combined effect of surface texturing and ER lubricant provides enhanced values of minimum fluid film thickness to avoid chances of metal-to-metal contact. Further, the stability of the bearing system is improved under the combined influence of surface texturing and ER lubricant. ACKNOWLEDGMENTS Adesh Kumar Tomar and M.
