Bio-SynXtra™ Stern Tube Lubes are specially designed, biobased synthetic formulas that replace conventional mineral oil based lubricants for lubricating bearing sets in ship stern tubes and certain designed retractable fin stabilizers and controllable pitch propeller systems. They are ultimate biodegradable and specifically designed to provide the proper emulsification of seawater for improved lubrication in wet conditions. In ASTM D-1401 modified test, 20% water in oil emulsion remained thick and stable for 60 minutes. An environmentally friendly additive system has been developed that provides excellent anti-wear, anti-oxidation, and anti-foam performance and the fluids are highly inhibited to prevent wear and corrosion, if up to 20% seawater temporarily enters bearing and gear-set areas. They are compatible with yellow and white metals and petroleum oils they come in contact with. The antiwear performance is enhanced by use of the Stabilized* biosynthetic base oils which provides an exceptional oily boundary film protection. There super high viscosity index naturally improves the fluid film strength between metal surfaces and provides additional load carrying properties. They are formulated to provide seal conditioning for longer seal life, reduce oil leakage from the system, and heavier viscosities can serve as effective temporary leak control in the case of worn or damaged seals. To protect the environment and equipment, damaged seal must be repaired as soon as possible according to VGP.
