Polymer bearing material is a copolymer polymer material that has all the versatility of sliding bearings, suitable for open lubrication systems and closed lubrication systems. With the use of different lubricating media in different fields, it can meet various environmental requirements.

The combination of raw materials from world-renowned companies, advanced production processes, and new technologies has achieved high wear resistance, versatility, and stability of polymer bearings. It has brought significant economic benefits to shipowners, shipyards, and shipyards, and greater social benefits to the localization of marine bearing materials.

Physical & Mechanical Properties of Marine Polymer Bearing

Application

The application areas of polymer bearings in marine rudder systems mainly include:

Rudder shaft bearings: support the rudder shaft to ensure stable rotation of the rudder blades.

Guided bearings: guide and support the movement of rudder blades, ensuring their stability and smoothness during operation.

Limiting bearings: limit the rotation angle of the rudder blades to ensure the safety and stability of the rudder system.
