Water-lubricated shaft bearing with outer resin shell for marine shaft lines, stern tubes, and propeller shaft systems. The cylindrical shaft bearing combines a hydro-/water-lubricated rubber bearing with a stable resin outer shell and functions as a support and sliding bearing around a rotating propeller shaft.
Water acts as a lubricant between the propeller shaft and the rubber inner bearing surface during operation. The rubber bearing features longitudinal grooves, which support water supply and contribute to reduced friction. The outer resin shell encloses the rubber bearing and provides a smooth, cylindrical exterior for mounting in a bearing housing or stern tube.
The product is available in several dimensions for different shaft lines. Select the variant based on the propeller shaft diameter, the inside diameter of the bearing housing or bushing tunnel, and the available installation length. Compatibility with specific engines, gears, drives, or boat models is not specified, so all measurements must be verified directly on the actual installation before mounting.
