ABSTRACT:
A stern tube bearing system for contra-rotating ship's propellers with concentric shafts is configured such that the oil feed to the bearing for the inner shaft is configured so that essentially only the oil ducts located in the lower portion of the rotational path of the bearing are in communication with the oil supply to essentially supply a substantial portion of the oil flow to the lower, load bearing surfaces of the bearing.
