Thordon has over 35 years of experience designing
long life marine bearings that operate without oil and grease.
Since our bearings have zero impact on the environment
they not only meet but exceed all environmental regulations
while reducing your vessels operating costs.

  • Reduced operating costs
  • Zero environmental impact (no oil or grease required)
  • Reduced maintenance
  • Turnkey engineering and installation support
  • High abrasion resistance
  • Superior resistance to shock loading and vibration
  • Industry leading wear life guarantees
  • Fitted to over 2,000 ships

“EPA recommends that all newbuild vessel operators endeavour to use seawater-based systems for their stern tube lubrication to eliminate the discharge of oil from these interfaces to the aquatic environment.”
