The Becker Flap Rudder with closed linkage system is the solution for the most difficult environmental conditions. Its sophisticated design incorporates the benefits of a flap mechanism, which is protected in a hydrodynamically-shaped top section of the rudder blade with a progressive flap angle ratio.

Semi-balanced rudder with a certain part of the blade area put forward of the turning axis. Like the balanced rudder, the certain area forward of the turning axis will cause water pressure on this portion to counterbalances the water pressure of the after portion.

The upper rudder carrier is a bearing of the ship's rudder device to support the rudder stock. It was mounted on the deck between the steering gear. The upper rudder carrier can not only ensure that the rudder stock does not fall into the water..

Rudder blade are classified in three ways. According to the position of the rotation axis: the rudder can be divided into the unbalanced rudder , semi-balanced rudder and balanced rudder . According to the connection type with the hull..

The rudder stock refers to the shaft on which the rudder blade rotates, which is used to bear and transmit the force acting on the rudder blade and the force of the rudder to the rudder turning device. Its reaction force makes the ship steer. .

The lower rudder bearing is a vertical sliding bearing with lateral force. It is widely used in various inland river boats. This type of lower rudder bearing is used together with CB*3145-83 upper rudder carrier.

The Light Roller Upper Rudder Carrier (A type roller upper rudder carrier) can apply to the rudder which the load isn't heavy and the revolving degree isn't large. And the diameter range of the rudder stock is Φ40-Φ150...

The Heavy Roller Upper Rudder Carrier (B type roller upper rudder carrier) can automatically adjust the centre of gravity, it especially can apply to the hanging rudder whose the load is heavy and the revolving degree is large...

The Marine Roller Upper Rudder Carrier (C type roller upper rudder carrier) has the function of sealing. And it has automatic centering.The water-tight upper roller rudder bearing is very suitable for heavy load of hanging rudder.

Marine Semi-spade rudder The upper half of the semi-spade rudder is supported on the rudder button at the rudder post or on the rudder arm, and the lower half is a spade rudder. It is mostly used for sea-going ships that do not require high performance and as a side rudder for inland ships..
