    2017-1-1 · Because of very less research work in case of cylindrical roller bearing, the authors have decided to work on cylindrical roller bearing (NJ 305). The study is going to be done in three steps. First step is development of mathematical model by considering the nonlinearity, second is numerical solution of coupled nonlinear equations and finally, analysis of dynamic behavior of motion by using various tools.
