The table below shows all key dimensions of the 4SF000 series
self-aligning top roller bearings. This bearing type is watertight
between the outer housing and inner housing due to the use of O-rings.
The measurement S is the outside diameter for the lip seal for sealing
from above.

| The applications for the 4SF000 series bearing: |
| The 4SF000 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 aluminium outer housing with an inside sphere turned out. A one
piece delrin ball is located in the sphere and is sealed to the outer
housing by an O-ring. The inner housing is pushed inside the delrin ball
and also sealed with an O-ring. This construction creates a watertight
situation between the rotating inner housing and the fixed outer housing.
The inner housing will always have one set of rollers. It's therefore
important to check that when the bearing diameter is above 90 mm, the
maximum working load isn't exceeded. If the calculated working load is
above the maximum working load, one should choose bearing type 44000. The
disadvantage of this bearing is the fact that top of the bearing, the
rudder stock and locking ring stand out above deck. If this is not
acceptable, one should choose the bearing type 4S000Z or use it under
deck. |
