stern tube bearing

A stern tube bearing is a critical component in ships that supports the propeller shaft and transfers radial loads from the propeller to the ship's structure. These bearings, typically of the slide bearing (also called journal or plain bearings) type, are housed within the stern tube, a hollow structure that also contains seals and may be filled with oil, grease, or water.

Bronze rubber bearing, bronze rubber bush for water lubricant for marine industry. Naval brass rubber bush adapt equally well to strut and stern tube mounts. And are often used effectively as rudder-stock and pintle bushings. Bearing diameters are precision fitted to the designated shaft size with the correct clearance for efficent water lubrication. External brass shells are machined and polished to provide easy fitting. Specially formulated oil and chemical resistant ntrile rubber is securely bonded to the shell. Unit with thin shells are available for the struts of small craft. Sleeve bearings are usually installed by light press-fitting and locked in place with once pointed set screws
