Abstract: Vegetable oils have a unique characteristic specifically in terms of environmental issues and are preferred as a potential bio lubricant to replace existing mineral oil. The main objective of this paper is to review the study of vegetable oil characteristics and challenges faced in the future as a future replacement of conventional oil specifically in the application of journal bearing. Surface modification of journal bearing has gained significant attention in recent years because of their enormous potential to increase the performance of journal bearing. Therefore, in this article, the potential performance of textured journal bearing by using mineral and vegetable oil as a lubricant is thoroughly reviewed. Nowadays, textured journal bearing and vegetable oil have attracted attention to the various applications in the industry. In line with the rapid development of the modification technique of journal bearing surface, the secondary objective of this paper is to provide a summary on the effect of different shapes or geometries applied, the effect on the bearing surface of the journal of complete textured or partial textured, and the effect of textured position on either the convergence or divergence area. The combination of vegetable oil as a future replacement of mineral oil as well as modification surface texture of journal bearing will become a great finding as it will improve the performance of journal bearing and at the same time can promote the application of environmentally friendly lubricant. Finally, summaries and conclusions are presented according to the reviewed and previous articles and data.
