Roller upper rudder carrier is an important component used in ship rudder systems. It is mainly used to support and rotate the rudder stock of the ship, ensuring that the rudder plate can rotate flexibly, thereby achieving ship manoeuvring.

The structure and types of roller upper rudder carriers mainly include the following:

Type of roller upper rudder carrier:

The structure and main parameters of sliding watertight rudder carriers:

A type:

B type: 

C type:

Performance or requirements for sliding watertight rudder carriers:

1. The surface of the rudder carrier body should be smooth and free of cracks, sand holes, and other defects that affect strength.

2. Fasteners should be galvanized.

3. The rudder carrier should be inspected and accepted by the technical inspection department of the manufacturing plant, and a certificate of conformity should be issued.

The design and selection of rudder carriers on these rollers are mainly determined based on the specific requirements of the ship, the design load of the rudder system, and operating conditions. Different rudder bearing structures and types can provide stable and reliable manoeuvrability for ships, thereby ensuring the safety of navigation.
