Thordon has a long history of proven performance with submarine applications, in particular, propeller shaft bearings. Naval tests against several other bearing materials have shown that Thordon SXL propeller shaft bearings have the lowest dynamic friction, the lowest breakaway friction and least tendency to cause stick slip. Other submarine applications include fin stabilizers, diving plane bearings, periscope bearings and torpedo launcher bearings.

  • Low acoustic signature
  • Low friction and low operating speed
  • Impact/shock resitance
  • High abrasion resistance
  • Reduced docking frequency
  • Non-catastrophic failure

    Canada's Support for Canadian Manufacturer, Thordon Bearings: A Highly Successful Partnership

    Feb 25, 2020
    Thordon pursued the Halifax-class frigates throughout the late 1980s and early 1990s, only to lose out to rubber, the dominant naval bearing at the time. When the rubber bearings could not meet the HMCS Halifax’s demands during sea trials, the Royal Canadian Navy (RCN) knew who to turn to. Thordon’s revolutionary COMPAC propeller shaft bearing design allowed for hydrodynamic operation at low shaft speeds and a low acoustic signature, passing sea trials very successfully. Thordon’s COMPAC tailshaft bearings went on to enjoy a 26-year wearlife run in the Halifax’s A-Brackets, three times the life of Thordon’s closest bearing competitor.

    Canadian Coast Guard Provides First Icebreaker Reference for Thordon's SeaThigor Seal

    Apr 15, 2019
    Thordon Bearings has received a Canadian Coast Guard contract to supply six award-winning SeaThigor shaft seals for retrofit installation to three purpose-built icebreakers. The order follows the success of the 2017 installation and subsequent operation of SeaThigor seals aboard the oceanographic and hydrographic survey vessel CCGS Hudson, for which a procurement agreement was signed with the Government of Canada under its Build in Canada Innovation Program (BCIP).
