Dredge bearings

Thordon Composite is a two component bearing formulated specifically for use in very abrasive environments such as water lubricated cutterhead shafts.


  • Proven bearing wear life - lasting twice as long as rubber
  • Reduced maintenance down time
  • Water lubricated - no grease
  • Easy installation

Thordon Composite has been consistently outperforming rubber in dredge cutterhead bearing applications since it was introduced in the 1970's. Composite bearing wear rates in dirty abrasive conditions are typically half that of rubber bearings reducing maintenance downtime over the life of the vessel. Thordon also supplies grease free ladder trunnion and drive shaft bearings for dredge vessels.

Composite bearings are available in a full range of sizes in both tube and stave configurations.
