Abstract

Provided is a bearing for supporting the propulsion shaft of a ship, with which it is possible to form a water coating with excellent lubricating characteristics on a sliding surface between the bearing and the propulsion shaft, and which is excellent in wear resistance and is economical.　A bearing according to the present invention supports the propulsion shaft of a ship and includes, on an inner peripheral surface of a cylindrical shell, a sliding layer and an elastic layer in this order in the radial direction from the cylinder center, wherein the sliding layer has: a load action portion which is on the lower surface side of the inner peripheral surface of the shell and on which a load of the propulsion shaft acts, the center angle θ thereof being in a range of θ=60°-180° with the axis of symmetry being the vertical axis; and a cooling action portion which opposes the load action portion and is provided with a plurality of required water cooling grooves on both ends being the first and last. The vertical axis refers to the axis of symmetry of a lateral cross section of the shell parallel to the center of gravity direction of the propulsion shaft.
