Thordon Bearings manufactures a seawater lubricated propeller shaft bearing system that is unlike traditional water lubricated rubber bearing systems. It uses elastomeric polymer bearings designed uniquely to offer desirable performance and operational benefits.  The low friction of the Thordon bearings and the early hydrodynamic film development creates an acoustically quieter bearing.

  • Survivability (non-catastrophic failure mode)
  • Low friction
  • Low acoustic signature
  • Ease of maintenance


  • Reduced docking frequency
  • Longer bearing wear life
  • Typical 3-4 year life cycle extended
  • Tapered key allows for easy bearing inspection without shaft withdrawal
