Thordon TG100r

is a new mechanical seal for 86 mm (3.375”) to 305 mm (12”) propeller shafts found in workboats, dredgers, tugs, yachts, patrol craft and other coastal vessels operating in either clean or dirty, abrasive-laden water.

Manufactured to the same exacting standards as our high performing range of Thordon bearings, the TG100r seal uses 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
Manufactured for long wear life providing lowest life cycle costs
Wedge “lock” design ensures the rotary face is perfectly square to the shaft
Unlimited shelf life on elastomeric bellows
Hydraulically balanced to accommodate various drafts

BENEFITS

BENEFITS OF THORDON SEAWATER LUBRICATED PROPELLER SHAFT BEARINGS

Long Wear Life

With over 35 years experience supplying marine propeller shaft bearings, in use service has proven that Thordon bearings provide significantly longer wearlife compared to the bearings they replace. Thordon bearings often outlast competitive products by 50% to 100%, or more, significantly reducing overall life cycle operating costs and increasing propulsion system. reliability.

Four Grades/Multiple Configurations Available

Thordon propeller shaft bearings are available in four different grades and multiple configurations for the optimal bearing solution for each owner’s specific application and operating profile.

Pollution Free

Thordon water lubricated propeller shaft bearings totally eliminate the use of oil resulting in zero risk of pollution.

High Abrasion Resistance

Due to their tough, elastomeric properties, Thordon bearings can resist abrasive wear by tending to defect, and then reject, abrasive particles allowing them to be fushed through the bearing and not become embedded.

Accommodates Edge Loading

Under edge loading conditions caused by minor shaft misalignment, elastomeric Thordon bearings defect slightly, effectively spreading the load and reducing potential bearing wiping and shaft wear.

Low Friction

Thordon’s static and dynamic coefficients of friction are both lower than other materials commonly used for water lubricated propeller shaft bearings. Lower friction leads to reduced break away torque, longer life and elimination of stick-slip and noise.

High Resilience/Impact Resistance

Elastomeric Thordon bearings tend to absorb impact loads, increasing resistance to damage from pounding during operation or in heavy seas.

Reduced Docking Time

Thordon recognizes the need for quick response to customer needs. To ensure tight docking schedules are met, Thordon provides the following advantages for shipyards and owners:

i) Worldwide Stock Availability – With Thordon’s network of distributors in over 100 countries around the world, inventory is available quickly at all major ports. When necessary, emergency shipment from the factory within three business days is possible.
ii) Easily Machined and Fitted – Asbestos and dust free, easily machined, and one seventh the weight of metals, Thordon bearings can be quickly installed in position by freeze fitting. Lighter rigging may be used and Thordon will not chip or crack during handling while frozen.

Extensive References

With over 35 years of experience supplying water lubricated propeller shaft bearings, Thordon has developed extensive lists of references, which are available upon request.

Full Classification Society Approvals

Thordon propeller shaft bearings are approved by all major Classification Societies and can be specified and installed with confidence.
