Water-lubricated shaft bearing with brass shell for marine shaft lines, stern tubes, and propeller shafts. The cylindrical design combines an inner bearing made of hydro-lubricating rubber with a dimensionally stable outer shell or brass sleeve. Water acts as a lubricant around the rotating shaft, making the bearing suitable for traditional installations with inboard engines.
The bearing is available in several imperial-based dimensions for various shaft and bearing housing measurements. Choose a variant based on inner diameter, outer diameter, and total length:

Always check the propeller shaft diameter, the inner diameter of the bearing housing or stern tube, and the available mounting length before purchase and installation. The dimensions are nominal imperial measurements used in, among others, American, British, and Australian shaft installations. Compatibility with specific boat, engine, or drive models is not specified.
