*L/D ratio may vary depending on actual shaft loading and the anticipated operating profile of the vessel.

Full Form TubesFull form Thordon tubes are the easiest Thordonconfiguration to install as the entire bearing may be quicklyfrozen in dry ice or liquid nitrogen and quickly installed inone piece. Full form tubes are also used if a split bearing

design is desired, allowing inspection or renewal of thebearing without removing the shaft. Thordon’s uniquesingle key design, where only the non-metallic Thordonbearing halves are removed, facilitates replacement of thebearings in a few hours, even underwater.

Propeller Shaft Bearing Configurations

Tapered Key Carrier Design – Originally designed for Disney Cruise Lines, this design allows the bearings to bewithdrawn, inspected and re-installed or replaced in a matter of hours.

Long Wear LifeReferences from over 35 years experience supplyingmarine propeller shaft bearings have proven that Thordonbearings provide significantly longer life compared to thebearings they replace. Thordon bearings often outlastcompetitive products by 50 to 100%, or more,significantly reducing overall life cycle operating costsand increasing propulsion system reliability.

Four Grades/Multiple ConfigurationsAvailableThordon propeller shaft bearings are available in 4different grades and multiple configurations to allowselection of the optimal bearing solution for each owner’sspecific application and operating profile.

Pollution FreeThordon water lubricated propeller shaft bearings totallyeliminate the use of oil resulting in zero risk of pollution.

Corrosion ResistantElectrically inert, Thordon bearings resist seawatercorrosion at both the bearing surface and the interfacebetween the bearing and the housing, thereby preventinga galvanic cell from forming.

High Abrasion ResistanceDue to their tough, elastomeric properties, Thordonbearings resist abrasive wear by tending to deflect, andthen reject, abrasive particles allowing them to be flushedthrough the bearing and not become embedded.

Accommodates Edge LoadingUnder edge loading conditions caused by minor shaftmisalignment, elastomeric Thordon bearings deflectslightly, effectively spreading the load and eliminatingpotential bearing wiping and shaft wear.

Choose the Optimum Thordon BearingGrade and Configuration for Your Needs

During the more than 35 years Thordon Bearings hasbeen supplying water lubricated bearing systems to themarine industry, wide variations in water quality rangingfrom clean to very abrasive, have been encountered.Rather than promoting the concept that one bearingsolution will work in all types of conditions, Thordon hasdeveloped four different bearing grades from which theoptimal bearing solution for each specific application andvessel operating profile may be selected.

Each individual grade offers unique differences relating tofriction, hydrodynamic operation and resistance to thirdparticle abrasive wear which can be used to determine thebest bearing for your vessel operating profile.

Low FrictionThordon’s static and dynamic coefficients of friction areboth lower than other materials commonly used for waterlubricated propeller shaft bearings. Lower friction resultsin reduced break away torque, longer life and eliminationof stick-slip and noise.

High Resilience/Impact ResistanceElastomeric Thordon bearings tend to absorb impactloads, increasing resistance to damage from poundingduring operation or in heavy seas.

Reduced Docking TimeThordon recognizes the need for quick response tocustomer needs. To ensure tight docking schedules aremet, Thordon provides the following advantages forshipyards and owners.

i) Worldwide Stock Availability – With Thordon’s networkof distributors in over 100 countries around the world,inventory is available quickly at all major ports. When

necessary, emergency shipment from the factory withinthree business days is possible.

ii) Easily Machined and Fitted – Asbestos free, easilymachined, and one seventh the weight of metals,Thordon bearings can be quickly installed in positionby freeze fitting. Lighter rigging may be used andThordon will not chip or crack during handling when frozen.

Extensive ReferencesWith over 35 years of experience supplying waterlubricated propeller shaft bearings, Thordon hasdeveloped an extensive list of references, which isavailable upon request.

Full Classification Society ApprovalsThordon propeller shaft bearings are approved by allmajor Classification Societies and can be specified andinstalled with confidence.

Page 5Page 4

Thordon COMPACThordon COMPAC is a high performance water lubricated bearing system primarily for“blue water” operating conditions. Specially formulated with a low coefficient of friction to reduce startup friction and eliminate stick-slip, COMPAC’s unique configuration isdesigned to promote early formation of a hydrodynamic film at lower shaft rpm. The lower(loaded) portion of the bearing is smooth, while the upper half of the bearing incorporateswater grooves for lubrication and cooling. Thordon COMPAC bearings are available ineither full form tubes or split configuration depending on the design requirements.

Thordon XLOur traditional standard propeller shaft bearing grade, Thordon XL is a generalpurpose bearing offering superior performance compared to other bearingscommonly used in propeller shaft applications. XL provides good balance betweenlong wear life, low coefficient of friction, reasonable abrasion resistance and costeffectiveness. Thordon XL is available in a wide range of sizes in both tube andstave configurations.

Thordon SXLThordon SXL offers a lower coefficient of friction for reduced break-away torque andsmoother operation at lower shaft RPM, increased resistance to third particle abrasivewear and improved wear life compared to XL. Available in a wide range of sizes, SXLcan be specified in either tube or stave configurations.

Thordon CompositeSpecially formulated to provide superior wear life in very abrasive water conditions suchas inland river systems, Thordon Composite bearings operating in combination with hardcoated nickel-chrome-boron shaft sleeves routinely outwear rubber propeller shaftbearings by a factor of two or more. More than 25 years experience on hundreds of pushboats and other vessels operating on America’s muddy Mississippi River system confirmreal-life bearing wear at between 0.010” – 0.015” (0.25mm - 0.38mm) per year.Composite bearings are available in a full range of sizes in both tube and staveconfigurations as well as brass backed flanged and non-flanged bearings in industrystandard sizes.
