Thordon Propeller Shaft Bearing Systems

Overview

RiverTough bearings run in combination with hard-coated nickel-chrome-boron (NiCrB) Thordon shaft sleeves routinely outlast rubber bearings by a factor of two or more in the most abrasive operating water conditions. RiverTough offers increased resilience compared to rubber bearings offering easier alignment and less edge loading (installation at 3:1 vs. 4:1 L/D ratio).

Thordon RiverTough bearings can be installed using an interference freeze fit or bonded in place using a Thordon-approved adhesive. An interference fit is often recommended for new build installations where the housing bore is consistent and concentric. Bonding is often the best option for repair installations where the housing bore may not be ideal.

COMPAC Overview

A Thordon COMPAC open seawater lubricated propeller shaft system offers considerable advantages to ship owners, not only in bearing wear life predictability and reliability, but they are also cheaper to maintain, easier to install and are future compliant.

SXL Overview

Thordon SXL offers a lower coefficient of friction for reduced break-away torque and smoother operation at lower shaft RPM, increased resistance to third particle abrasive wear and improved wear life compared to XL.
