Stern Tube

High viscous, high-performance lubricant oil formulated from selected paraffinic base oils and specific additives that quickly emulsifies in presence of sea water, maintaining stable the emulsion. The product has excellent lubrication properties and protects critical surfaces of the stern tube from corrosion, even during long periods of time working in severe operating conditions.
Specially recommended for stern tube bearings/closures, where emulsifying lubricants are necessary. It is especially developed to lubricate Cedervall type stern tubes installed in vessels and for certain fin stabilizer bearings installed in passenger ships

EAL (environmentally acceptable lubricant) hydraulic fluid specially developed for vessel stern tubes. It is also suitable for any application where a VGP (Vessel General Permit) 2013 legislation compliant biodegradable product is required.
The product has an excellent protection against rust and corrosion and good oxidation stability, water separability and foam suppression. Moeve Sterna Bio exhibits a high viscosity index that remains stable over the time and which allows for operation over a wide temperature range.
It is particularly recommended when there is a risk of water contamination in hydraulic systems working in severe operating conditions.
The product is fully compatible with the typical elastomers used in hydraulic equipments.
