Self-aligning lower roller bearings type 4S000


Type 4S000 bearing

The table below shows all key dimensions of the 4S000 series self-aligning bottom roller bearings. This bearing type is watertight between the outer housing and inner housing due to the use of O-rings.  The measurement T is the outside diameter for the rudder tube when mounted in the outer housing. The measurement S is the outside diameter for the rudder tube or lip seal when mounted in the inner housing.

The applications for the 4S000 series bearing:
The 4S000 series bearings are suitable for GRP and wood core cruising and racing yachts. 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 43000.
The bearing can be sealed by a rudder tube or double lip seal inside the top register of the inner housing, or for maximum security a rudder tube in the top register in the outer housing.
