ThorPlas-Blue

ThorPlas_3_bearings

The versatility of Thordon technology provides Navies and Coast Guards around the world with pollution-free, low maintenance and long lasting solutions for deck machinery and other unique bearing applications using ThorPlas-Blue, HPSXL TRAXL and other Thordon grades.

ThorPlas-Blue is a low friction polymer bearing designed for problem areas that have frequent maintenance where grease lubrication is not always possible and there is a high cost consequence of seized bushings. Capable of operating pressures to 45MPa (6,527 psi), ThorPlas-Blue can be easily back-fit into virtually all applications where greased bronze is currently installed.

Operating above and below the waterline, ThorPlas-Blue is a direct replacement for all greased bronze bearing applications eliminating the polluting grease, labour time and cost.

Typical applications include davit bearings, fairlead, sheave and pivot bearings, water tight door bushings, cargo ramp bushings and crane bearings.

HPSXL TRAXL is the HPSXL polymer in a bronze-backed configuration for high pressure applications with permissible peak static pressure up to 70 MPa (10,000 psi) with a very low dry coefficient of friction. HPSXL TRAXL is resistant to shock loading and vibration and is excellent for clean, oscillating, water lubricated applications requiring high load capability.

Other Thordon grades may also be possible for different operating environments depending on the pressures, speed and abrasives. Contact us for your unique naval bearing issues.

    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.

    Coast Guard Solves Shaftline Problems with Thordon Propeller Shaft Bearing System

    Apr 30, 2018
    The Canadian Coast Guard (CCG) has again selected Thordon Bearings’ COMPAC water lubricated propeller shaft bearing system for two icebreakers, the Pierre Radisson scheduled later this year and the Des Groseilliers scheduled to be installed in the 2020 dry dock. CCG, a long-standing customer of Thordon Bearings, decided to retrofit the award-winning COMPAC system to the 6098gt Des Groseilliers following more than 17 years’ operational experience with the Thordon solution. The new COMPAC bearings will be supplied and machined by Thordon distributor RMH Industries of Québec, Canada.
