Tribology of Journal Bearings Subjected to Boundary and

A journal bearing is a journal (such as a shaft) which rotates within a supporting sleeve or shell [1]. Hydrodynamic journal bearings use the rotation of the journal to pressurize a lubricant which is supplied to the bearing to eliminate surface-to-surface contact and bear the external load as seen in Figure 1 [4]. Figure 1: Journal Bearing [4]
