Abstract
A journal bearing for a gear driven pump includes a bearing body having a bearing body circular opening that defines a bearing surface along a length of the bearing body and a face plate adjacent to the bearing surface. The bearing surface is configured to carry a gear shaft load through a hydrodynamic fluid film pressure between a load surface of a gear shaft and the bearing surface. The bearing surface is formed from a leaded bronze material and the face plate is formed from a copper-nickel alloy.
