NORDEN 788 Marine - stern tube bearing

  • Environmentally friendly water lubricated bearing.
  • Free of all risks, polution and costs assosiated with stern tube oil leakage.
  • Low wear and friction levels ensures long service life.
  • Approved by major classification societies .
Description
Norden 788 Marine is a polyester based composite material that can trace its roots to British Steels development for steel mills in the 1950's. 
Since then the material has evolved, and been utilized in thousands of applications. 
Norden Marine Bearings has further developed and enhanced this vertatile material, and Norden 788 Marine is now among the worlds leading materials with regards to low friction performance. The low friction is a key attribute for making Norden 788 Marine well suitable for propeller shaft bearing. The wear and heat generation will occur during accelleration and decelleration of the shaft, low friction level reduce both these parameters and ensures long lifecycle of the bearing. 
Material
Norden 788 is a high load composite bearing material made of specially manufactured synthetic fabric reinforcement using a composite construction process which is impregnated with thermosetting resins, solid lubricant fillers are added which make it suitable for dry running applications.

Key caractheristics
Low friction, high wear resistance, low thermal expansion and swell rate
