The table below shows all key dimensions of the 43000 series self-aligning bottom roller bearings. The measurement T is the outside diameter for the rudder tube which will be mounted inside the bearing housing. To achieve the high working load above 79 mm, two sets of rollers are mounted.

|The applications for the 43000 series bearing:|
|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. For details please see the installation in aluminium hulls section.
