TOP RUDDER BEARINGS Rudder Bearings with Rollers for Wheel Steered Boats
TYPE 42000Z Top Roller Bearings with Deck Cover for Rudder Shaft Diameters 50mm - 80mm
The 42000Z series bearings are suitable for all types of hull material. This bearing is the perfect solution as top bearing for cruising and cruising/racing yachts as it combines a horizontal roller bearing with a vertical roller bearing and a deck cover. Due to the vertical roller bearing arrangement, the rotation of the rudder shaft is extremely smooth. The bearing is ideal as a deck or cockpit floor bearing as it doesn’t extend beyond the deck level, especially when the deck flange is let into the teak deck. In combination with emergency tiller arrangement type 1, a quick and safe access to the emergency steering is achieved. The bearing is available in three sizes, so take notice when designing the rudder stock. TYPE 4S000Z Top Self-Aligning Roller Bearings with Deck Cover for Rudder Shaft Diameters 30mm - 165mm
Rudder Shaft Diameter (50mm - 80mm)
The 4S000Z series bearings are suitable for all types of hull material. This bearing is the self aligning version of the 42000 type and the perfect solution as top bearing for cruising/racing and racing yachts as it combines a horizontal self-aligning roller bearing with a vertical roller bearing and a deck cover. Due to the two way vertical roller bearing arrangement, the rotation of the rudder shaft is extremely smooth, even on racing yachts where the rudder could be lighter than the water, so generating an upwards lift. The bearing is ideal as a deck or cockpit floor bearing as it doesn’t extend beyond the deck level, especially when the deck flange is let into the (teak) deck. In combination with emergency tiller arrangement type 1, a quick and safe access to the emergency steering is achieved. The bearing is available in specific sizes, so take notice when designing the rudder stock. Recommended torque setting for the lock ring is 7Nm for M6 set screws and 35Nm for M10. This assumes stainless steel 304/A2 cup point set screw, made to DIN916/ISO4029, fitted to a dry, ungreased thread. It is recommended to pre-drill the stock at set screw locations to ensure a durable lock ring fit. Rudder Shaft Diameter (30mm - 165mm)
TYPE 5T000Z(S) Top Roller Bearings with Deck Cover for Rudder Shaft Diameters 40mm - 140mm
The 5T000ZS bearings can be used in a rudder stock to deck angle of 0° to 25° and the 5T000Z bearings in a rudder stock to deck angle of 0° to 21°. The function of this bearing is similar to the 4S000Z-20 group, but the bearing is lower priced as it isn’t machined out of solid aluminum, but casted to shape. The vertical locking is achieved with an additional locking ring (46xxx) not included. The deck cover is easy removable via a bayonet connection for the 5T000Z bearings and a threaded connection for the 5T000ZS bearings.
TYPE 4SF000H Hanger Type Self-Aligning Top Roller Bearings for Rudder Shaft Diameters 40mm - 140mm
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.
