A propeller shaft bearing for use in boats has an inner layer (10) made from a hard resilient material and a further concentric layer (11) made from a soft resilient material. The bearing may be water lubricated, and the further layer (11) may be provided with blind bores (17) which in use are continually deformed to assist in pumping water to the bearing surfaces. The two layers (10, 11) may be cased in a composite tubular member (12) comprising a metal/rubber/metal sandwich. The bearing provides adequate support for the propeller shaft (3) in addition to preventing or minimising transmission of vibrations and other noise from the propeller shaft to the ship's hull. <IMAGE>
