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

    Canadian Coast Guard Opts for Thordon Bearings to Save Tax-Payers Money

    Mar 23, 2021
    CCGS Terry Fox, one the largest icebreakers in the Canadian Coast Guard (CCG) fleet, has returned to service with new Thordon propeller shaft bearings after concluding that fitting laminate phenolic bearings would extend dry dock time and costs. The 88m (289ft) long vessel, built in the 1980s had been operating Thordon’s water lubricated elastomeric polymer bearings on both shafts for 24 years. Then in 2018 the port shaft was retrofitted with a European made laminate phenolic-type bearing as part of a shaft alignment contract with the manufacturer.

    Canada’s Irving Shipbuilding has cited Thordon Bearings as one of a number of partners playing a pivotal role in ensuring the Royal Canadian Navy’s (RCN) new Arctic and Offshore Patrol Ships (AOPS) are capable of environmentally sustainable operations. The first two in a series of six twin-screw vessels entrusted to Irving Shipbuilding, have been put to water with Thordon’s COMPAC water lubricated propeller shaft bearings, which the shipbuilder says are “environmentally progressive” resulting in “zero risk of pollution”.
