Since times immemorial it is known that the application of a material classified as lubricant to two relatively moving surfaces causes motion. The real mechanism of lubrication was explained by Reynolds of the role of lubricants is to support the load between two moving curved surfaces and thus minimizing wear and energy losses reducing friction between them. Thus the proper knowledge and understanding of the process of lubrication becomes a prime necessity to improve standard of design and efficiency of the mechanical system. A study of the behavior of any lubricated system can be best made by developing a mathematical model based on the above factors which depends upon a given a physical situation. The bearing characteristics such as load, flow flux, friction force etc. depends upon the pressure generated in the film and the lubrication process. An attempt has been made to obtain the governing equation for pressure in the lubricant film that are surveyed and summarized in this paper
