Water-lubricated shaft bearing bush with resin outer shell for marine shaft lines, stern tubes, shaft brackets, and propeller shaft systems. The cylindrical bush combines an internal bearing surface of hydro-lubricating rubber with an outer shell of resin or synthetic resin.
The internal rubber bearing is designed for water-lubricated operation, where water acts as a lubricant around the rotating propeller shaft. Longitudinal profiled water and lubrication grooves channel water through the bearing surface and support stable function during operation.
The product series is available in various metric combinations of internal diameter, external diameter, and length. Internal diameters include 25, 30, 35, 40, 45, and 50 mm. External diameters include 35, 40, 45, 48, 50, 55, 56, 61, 65, 66, and 70 mm, while lengths include 100, 120, 160, 180, and 200 mm.
The internal diameter must match the nominal diameter of the propeller shaft, while the external diameter must correspond to the bore of the bearing housing, shaft bracket, or stern tube. Also, verify the available installation length before ordering or replacing. Compatibility is dimension-based, and no specific compatibility with particular engines, gears, drives, boat models, or makes is specified.
