The 4SF000H 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 4SF000H bearing is a special version of the 4SF000 completed with a double working vertical ball bearing. This bearing is also similar to the 4S000Z bearing without the deck cover. The typical application for this bearing is as top bearing on a rudder stock that is not extended to the deck, but mounted on a horizontal bulkhead at cockpit level.
