The invention discloses a large-damping water lubricated bearing with different longitudinal stiffness for a ship. The large-damping water lubricated bearing with different longitudinal stiffness forthe ship comprises a bearing bush; symmetrical bulges are formed at the two ends of the outer circumferential surface of the bearing bush; an intermediate constrained damping layer and an intermediatedamping layer are wrapped on the outer circumferential surface of the bearing bush between the two bulges in sequence; an end constrained damping layer and an end damping layer are wrapped on the outer circumferential surface of the bearing bush on the outer sides of the two bulges in sequence; the outer end surfaces of the end damping layer, the bulges and the intermediate constrained damping layer are in the same plane; the outer end surfaces of the end damping layer, the bulges and the intermediate constrained damping layer are bonded with a metal bearing sleeve simultaneously; an intermediate section is formed by the bearing bush which is positioned between the two bulges, the intermediate constrained damping layer and the intermediate damping layer; a transition section is formed bythe bulges and the metal bearing sleeve; a rear end section is formed by the bearing bush which is positioned on the outer side of one bulge, the end constrained damping layer and the end damping layer; and a front end section is formed by the bearing bush which is positioned on the outer side of the other bulge, the end constrained damping layer and the end damping layer. Relative inclination deformation of a propulsion shaft system in a tail bearing is reduced.
