RiverTough Tailshaft Bearings



 

320x190 - RiverTough

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. 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.

These five tugs are considered to be the first ship-assist tugs operating in the lower Mississippi fitted with both RiverTough bearings and TG100 seals.

Since the first installation in 2015, Harken Towing, which operates a fleet of ten shift tugs, five continuous tugs and nine aluminum water taxis, has installed RiverTough to an additional three tugs and plans to convert the remaining vessels at subsequent drydockings.
