摘要： A bearing system and journal which may incorporate either a sleeve or a ball bearing. The system includes a bearing journal having a sleeve bearing portion and a ball bearing portion. When a sleeve bearing is used in the system, a first end of the sleeve bearing is supported in the sleeve bearing portion of the journal, and a second end of the sleeve bearing is supported by a finger spring. The sleeve bearing and finger spring are retained within the journal by an end cap, which is press-fit into the ball bearing portion of the journal. When a ball bearing is used in the system, the ball bearing may be press-fit directly into the ball bearing portion of the bearing journal, or press-fit into a spacer, which is press-fit into the ball bearing portion of the bearing journal.
