Thordon Bearings

COMPAC Propeller Shaft Bearings

Thordon’s COMPAC propeller shaft bearings are great in blue water applications. COMPAC is a polymer alloy bearing which is seawater lubricated, eliminating the need for oil. Bearing wear is more gradual and predictable than competing materials, and installation and maintenance is easy.

Composite Cutterhead Bearings

Thordon Composite cutterhead bearings typically last twice as long as rubber bearings. Composite is formulated specifically for very abrasive environments. It requires no grease, and is easy to install using a freeze fit.

RiverTough Propeller Shaft Bearings

Thordon RiverTough propeller shaft bearings are specifically designed for workboats, pushboats, and tugs operating in dirty water. Vessels operating in the Mississippi River have shown that RiverTough lasts twice as long as rubber bearings. Like all Thordon marine bearings, RiverTough is grease- and oil-free and can be easily installed using a freeze fit or bonding.

SeaThigor Shaft Seals

Thordon SeaThigor shaft seals are designed for operating life and require no maintenance. In the event that the silicon carbide face seal are damaged, the inflatable emergency seal allows the propeller shaft to still turn in order to return to port.

SXL Rudder Bearings

Thordon SXL rudder bearings are pollution free and have been installed on over 4,000 vessels. SXL is low friction and self lubricating, eliminating the need for grease. It can also withstand high shock loads and edge loading. The material can be used for both the carrier bearings as well as the pintle and stock bearings.

TG100 Shaft Seals

Thordon TG100 shaft seals are specifically designed for use in vessels operating in dirty water. The seal requires no maintenance and is completely grease free. The TG100 has a unique “get home” feature which allows the propeller shaft to operate even with the emergency seal inflated. Currently, this seal covers shaft diameters of 3.375″ to 12″ (85.725 to 304.8 mm).

Thorplas Bearings

ThorPlas-Blue is a self-lubricating thermoplastic which can withstand pressures up to 45MPa (6,527 psi). The material has low friction and low wear in non-abrasive environments. As with other Thordon bearing materials, ThorPlas-Blue operates grease-free and is easy to machine.

Typical applications: Hydraulic steering systems, deck equipment

XL Rudder Bearings

Thordon XL is a general purpose bearing offering a good balance between long wear life, low coefficient of friction, abrasive resistance, and cost. XL has high resistance to vibration and shock loading.
