Simplex Sterntube bushes
While merchant shipping generally benefits from the standard design of Simplex sterntube bushes - cast-iron/lead-based white metal (GG-20) - the bushes intended for ships subjected to higher stresses, such as naval vessels or icebreakers, are made of nodular cast-iron/tin-based white metal (GGG-40).
The intercrystalline bonding of the materials provides the highest possible quality and durability.
The length of a bush is determined by the rules of the respective classification society. SKF Marine is able to supply bushes up to a length of 2,800 mm and an outside diameter of 1,200 mm. All bushes undergo a rigorous quality control process and are individually tested using ultrasonic techniques. Of course, the repair and remetalling of bushes is also possible - with extremely fast turnaround times. Get the answers - just call SKF Marine!
