Journal bearings are known to be intrinsic components in different marine applications. They are regarded as the most instrumental means by which large loads could be transmitted at mean speed of rotation. Hydrodynamic journal bearings, based on hydr

Lubrication of journal bearing in ship shafting systems is facing a problem in the slow speed range, where oil film created pressure depends on shaft speed, among many other factors. Hence, the slower the speed the lower the pressure will be, which s
