Abstract
A propeller system for ships includes a propeller shaft connected to be driven by a ship's drive shaft in order to drive the propeller of the ship connected thereto. The propeller shaft extends through a water-lubricated bearing located in the stern frame of the ship and the bearing is formed to include a first layer of hard rubber extending coaxially about the propeller shaft, a second layer of soft rubber arranged coaxially with the first layer and a tubular member exteriorly enclosing the water-lubricated bearing. Blind-ended bores are circumferentially distributed in the second layer and extend through approximately two-thirds of the length of the bearing.
