TOP RUDDER BEARINGS Rudder Bearings with Rollers for Tiller Steered Boats
TYPE 42000 Top Roller Bearings for Rudder Shaft Diameters 35mm - 350mm
The 42000 series bearings are suitable for all types of hull material. This type of top bearing can also be used on tiller steered boats. The rudder head will rest on the delrin ring, in this way achieving vertical locking. In yachts with a steering system a locking ring on top of the bearing will take care of the vertical locking. A special type of the 42000 series bearing (42... STP) with integral stops in combination with our tiller heads is available in 35 and 40mm. On this bearing, the top of the rudder stock and locking ring stand out above deck. For a flush mount, one should choose the bearing type 42000Z. TYPE 5T000 Self-Aligning Top Roller Bearings for Rudder Shaft Diameters 30mm - 120mm The 5T000 series bearings are low-cost self-aligning top bearings for light to medium loaded applications. As there is no aluminum inner housing between the rollers and the ball, the working load is lower that the 4SF000 type bearings. These bearings can be used in applications with relative bigger diameter rudder shafts like aluminum and carbon rudders. This type of top bearing can also be used on tiller steered boats. The rudder head will rest on the delrin ring, achieving on this way the vertical locking. A special type of the 5T000 series bearing (5T...STP) with integral stops in combination with our tiller heads is available in 35, 40 and 50mm. When the yacht has a steering system, a locking ring on top of the bearing will take care of the vertical locking. On this bearing, the top of the rudder stock and locking ring will stand out above deck. For a flush mount, one should choose the bearing type 4S000Z. 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 aluminum 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. On this bearing, the top of the bearing, the rudder stock and locking ring stand out above deck. For a flush mount, one should choose the bearing type 4S000Z or use it under deck.

TYPE 6BF PETP Self-Aligning Top Roller Bearings for Rudder Shaft Diameters 80mm - 200mm
The 6BF PETP Self-Aligning Roller Bearings are designed to be mounted as top bearing in a GRP or metal tube like Jefa 6D bearings. The bearing is made of PETP (also known as Arnite, Ertalyte, Sustodur & Ultradur), so it doesn’t contain any metals. The bearing ball can be easily dismounted out of the housing for installation safety or replacement if any future damage may happen.
