Propeller Shaft COMPAC

COMPAC

Thordon COMPAC is a high performance water lubricated bearing system primarily for “blue water” operating conditions. Specially formulated with a low coefficient of friction to reduce startup friction and eliminate stick-slip,

SXL

Thordon SXL offers a lower coefficient of friction for reduced break-away torque and smoother operation at lower shaft RPM, increased resistance to third particle abrasive wear and improved wear life compared to XL. 

Installed XL bearing

XL

Our traditional standard propeller shaft bearing grade, Thordon XL is a general purpose bearing offering superior performance compared to other bearings commonly used in propeller shaft applications. XL provides good balance between long wear life, low coefficient of friction, reasonable abrasion resistance and cost effectiveness.

SeaThigor

The Thordon SeaThigor Seal is a mechanical face seal for 300mm (11.8") to 750mm (29.5") water lubricated propeller shafts found in yachts, cruise ships, merchant ships and naval vessels. The SeaThigor has evolved from a design first tested in 2003 and improved during the next decade.

Bearing Condition Monitoring (BCMv2)

BCMv2

The Thordon Bearing Condition Monitoring (BCMv2) system supports the Classification Societies’ requirements for condition monitoring of marine vessel bearing wear inspection. The Thordon BCMv2 system provides a one-touch, remote indication of current bearing clearance. The measurement is displayed on the control panel located in the vessel.

“Spills always come at times when you do not need them, and they must be resolved as soon as possible. Prior to the switch to these seawater lubricated bearings, Flinter, like others, had been fined for oil pollution, especially in U.S. ports.”
