Abstract
A hydrodynamic fluid film journal bearing system includes a journal sleeve and one or more hydrodynamic fluid film foils positioned at least partially within the journal sleeve. The journal sleeve defines an inner diameter surface, an outer diameter surface, a wall thickness between the inner and outer diameter surfaces, and opposite first and second ends. The wall thickness of the journal sleeve is reduced at a first region located between the first and second ends, and a chamfered region is formed on the outer diameter surface of the journal sleeve between the first o-ring land and the first end of the journal sleeve.
