Product introduction
Nylon composite material
Nylon composite material is nylon as the matrix, by adding long fiber (carbon fiber, glass fiber, boron fiber, etc.) and graphite by centrifugal casting;
The material has high mechanical strength, impact toughness, wear resistance and self-lubrication, and is not only resistant to sediment and good vibration absorption as a water-lubricated bearing.
Application: stern bearing, pump, shaft-less propulsion
