Abstract: The journal bearing is used to support the shaft. Hence it is necessary to evaluate the performance of journal bearing operating under the boundary or mixed lubrication regimes in boundary or mixed lubrication regimes as there is direct contact in boundary regime while it is partial contact in mixed lubrication regimes. As wear is considerably more in boundary or mixed lubrication regimes hence it is necessary to measure the wear experimentally. These performance parameters to be evaluated by using the experimental set-up to study the influence of various parameters such as Temperature, frictional torque, coefficient of friction of the journal bearing.
