TG100 Tailshaft Seal


TG100_brochure_cover2015
Shaft Seal for Abrasive Water Conditions

The Thordon TG100 is a new mechanical seal designed specifically for 86mm (3.375") to 305mm (12") shaft vessels operating in either clean or abrasive-laden waters including workboats, harbor tugs, offshore supply vessels, yachts, ferries, fishing trawlers and self-propelled dredgers. 

Manufactured to the same exacting standards as our high performing range of Thordon Bearings, the TG100 seals use the highest quality, hard wearing silicon carbide faces and our proprietary elastomeric polymers to offer the best combination of strength/stiffness and flexibility/elasticity.

 
 
  • Unlimited shelf life on elastomeric bellows
  • Unique emergency seal allows stand-alone operation to get you back to port without damaging the seal
  • Elastomeric bellows accept axial/radial shaft movement and compensate for alignment issues
  • Manufactured for long wear life and reduced maintenance costs
  • Wedge "lock" design ensures the rotary face is perfectly square with the shaft
  • Hydraulically balanced to accommodate various drafts
  • Single supplier for bearings and seals

Unique Emergency Seal
 
A unique feature of the TG100 is the emergency seal that allows stand-alone operation. This not only ensures that you safely return to port but helps prevent permanent seal damage.

Maintenance-free Shaft Seals

The TG100 should require no periodic maintenance. A well maintained seal should require no parts within a 5-year drydock interval, however an additional "water port" allows for cleaning/flushing of dirt and abrasives deposited in the bellows over time.

    Thordon's Tailshaft Bearing and Seal Combo Proving to Save Vessel Owners Money in More Ways Than One

    May 19, 2020
    During a recent drydocking, the final vessel in a series of five ship-assist tugs has been successfully converted to RiverTough tailshaft bearings and Thordon’s TG100 shaft seals and has returned to work on the Mississippi River. 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.

    May 05, 2020
    Harken Towing, a western Canada-based workboat company with operations along the Fraser River, is converting its vessels’ tailshaft bearings to RiverTough following the success of the Thordon bearing system aboard the 14.54m (47.7ft) twin-screw tug Granny Hutch. 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.
