Abstract
A shaft assembly has a shaft and a journal bearing that is fixedly coupled to the shaft so that rotation of the shaft causes corresponding rotation of the journal bearing. A bearing race has an inner surface that defines a cylindrical bore and a lubrication groove that extends radially outward from the cylindrical bore. The journal bearing is rotatably disposed within the cylindrical bore of the bearing race.
