Abstract
The present invention is a self-lubricating bearing for a vertical shaft engine. A stub disposed within the journal bearing has a downwardly facing pocket which propels oil upward by centrifugal force during rotation of the shaft. The upwardly forced oil serves to lubricate the bearing above the stub. The lubrication system can be employed in both stub shaft and through shaft bearings.
