ABSTRACT:
A bearing includes an annular rubber-like member having a metal sleeve bonded on the inside diameter. One or more collars are sweated onto a shaft and provide one component of a lug and groove torque connection, the metal sleeve providing the other component. In one embodiment, a polymer liner is cooled and then inserted into the stern tube. When the polymer liner warms to ambient temperature, it expands into engagement with the stern tube and provides a surface for bearing engagement with the rubber-like member. Liners of this type are easily removed by removing the bearing, drilling a hole through the side wall of the liner parallel to the axis of the bearing and then pulling the weakened liner from the stern tube.
