The 43000 series bearings are suitable for all types of hull material. This bearing type combines a very simple installation with a very smooth operation under all circumstances as the bearing will always be aligned to the rudder shaft. The bearing consists of an heavy duty aluminium outer housing with an inside sphere turned out. A two piece delrin ball is located in the sphere. The inner housing is pushed inside the delrin ball. Above 79 mm, two sets of rollers are mounted to achieve a very high working load. As the delrin ball is mounted in two parts, the bearing is not watertight between the outer housing and inner housing, so a tube has to be used in the top register of the outer housing to achieve a proper sealing. This bearing is normally used in applications where the working load of the 4S000 type bearing isn’t sufficient. For aluminium hulls this bearing can provide the perfect solution: The outer housing can be welded into the hull, providing a very strong and fast installation and also saving a very expensive big tube.
