How Compac Stern Tube Bearing System Can Prevent Oil Pollution Thordonbearings a brief animation of how seawater lubricated compac propeller shaft bearings function. How a thordon compac stern tube bearing system works thordon water quality package provides a clean flow of lubricating seawater to the propeller shaft bearings. it takes only the seawater from the sea (through the sea chest), removes abrasive particles and pumps the water into the stern tube to lubricate the non metallic bearings.
How A Thordon Compac Stern Tube Bearing Works Youtube Since 1965 thordon has been providing water lubricated systems, this video examines the different components in the compac seawater lubricated propeller shaf. The compac conversion process. a pictorial overview of the 12 step process. step 1. engineering and suitability review. step 2. drain oil, remove shafts, clean and verify dimensions. inspect fwd and aft stern tube. remove the original white metal bearings. step 3. Compac bearings are at the heart of the award winning open seawater lubricated propeller shaft bearing system.the compac polymer alloy bearing is homogeneous (there are no layers of differing materials) with properties that are consistent throughout the wall thickness. the thordon compac bearing is designed in a 2:1 l d configuration in the aft. Bearings and returns to the sea. no stern tube oil is needed. compac non metallic bearings now offer performance similar to metal shaft bearings. one significant difference, however, is that the mild steel propeller shaft requires corrosion protection from the seawater. this may mean a higher up front cost for the stern tube bearing system.

Bearings and returns to the sea. no stern tube oil is needed. compac non metallic bearings now offer performance similar to metal shaft bearings. one significant difference, however, is that the mild steel propeller shaft requires corrosion protection from the seawater. this may mean a higher up front cost for the stern tube bearing system. It eliminates the use of stern tube lube oil hence no chances of oil pollution. there is no aft seal hence system and maintenance cost reduces. no need of lube oil storage tank. it eliminates installation of lube oil pumping system. the maintenance period of such bearing is minimum 10 years hence lower in service cost. For superior performance in propeller shaft bearing systems, thordon’s compac open water lubricated stern tube bearing systemoffers low friction, zero pollution risk and long wear life in blue water operation. another thordon first is the factory guaranteed wear life performance of thordon sxlself lubricating pintle and stock rudder bearings.
