TG100 Seal

Safe Return to Port Emergency Seal

A unique feature of the TG100 is that the emergency seal allows you to return safely to the nearest port if your primary seal is ever damaged.

Maintenance-Free Shaft Seals

The TG100 seal is designed to operate without any need for spare parts or maintenance between vessel docking periods. The elastomeric bellows and emergency seal have an unlimited shelf life, further reducing any need for expensive overhaul kits in the future. Combining these features with the use of only silicon carbide faces for both the dynamic and stationary faces, TG100 takes the work and cost out of your Workboat.

RiverTough Tailshaft Bearings

Long Bearing Wearlife in the Toughest Operating Conditions

RiverTough bearings run in combination with hard-coated NCB ThorSleeves routinely outlast rubber bearings by a factor of two or more in the most abrasive operating water conditions. Longer wear life has consistently been confirmed by owners of workboats, push boats, and tugs operating in the US inland waterways systems. But don’t take our word for it – Ask our users.

Save Money

It’s a fact. Workboats that operate with RiverTough tail shaft bearings are more reliable – they operate longer, require less maintenance, and have fewer dry dockings. This means less money spent and more money earned!

ThorPlas-Blue Tiller Arm Bushings

Reliable Operation

Ensuring reliable operation of all equipment installed above the waterline is a tough issue for any ship’s crew. Originally developed to replace greased bronze bearings, ThorPlas-Blue is lifetime lubricated – lubricants in the homogeneous polymer ensure a low, stable coefficient of friction, even as the bearing wears, while offering long bearing wear life with no maintenance.

High Load Capability

ThorPlas-Blue is used to replace highly loaded greased bearings, capable of design pressure up to 6527psi (45MPa).


ThorPlas-Blue Rudder Bearings

Grease-Free Operation

ThorPlas-Blue offers low friction and long bearing wear life without the use of grease. There is no maintenance due to the self-lubricating properties ensuring smooth operation. The use of rudder Thorseals will keep abrasives away from bearing and sleeve surfaces.

Superior Performance

ThorPlas-Blue offers good dimensional stability with tighter installed clearances due to lower water absorption and low thermal expansion.
