Sterntube Lubricants
In 2002, after 9 years of extensive R&D, Vickers Oils launched the world’s first commercially available range of biodegradable sterntube lubricants. Today we supply thousands of vessels with our award winning range of products, delivered globally with unparalleled experience and expertise. We have a growing range of environmentally acceptable lubricants (EALs) designed to provide excellent lubrication of the sterntube bearings. Our EAL range of sterntube lubricants are approved by many of the leading OEMs, for up to 5 years, and should always be used in accordance with OEM guidelines. To obtain more information click on the appropriate OEM link and please do not hesitate to contact us directly for more specific detail.
It is important to ensure that when changing the lubricant in the sterntube that the system is drained thoroughly of any used oil and flushed if necessary. Any residual oil may reduce the life of the fresh oil and impair its performance. We recommend the regular use of a comprehensive oil condition monitoring test suite appropriate to EALs.
Vickers Oils does not recommend the mixing of oils and will not accept any product liability where our EALs have been mixed with another fluid. Vickers Oils offers both emulsifiable and non-emulsifiable products depending upon user preference
Synthetic emulsifiable ester based lubricant
HYDROX BIO is an environmentally acceptable lubricant (EAL) based on synthetic esters which meets the detailed ecological definitions and requirements laid down in Vessel General Permit (VGP).
HYDROX BIO lubricants will absorb sea or fresh water entering the sterntube to form a fluid emulsion. This reduces the risk of free water being present and continues to provide the required lubrication and corrosion protection. Conventional oils do not emulsify in the same way and tend to separate, exposing components to free water and potential wear damage.
HYDROX BIO 68, 100 and 150 are the viscosity grades generally recommended by the bearing and seal manufacturers for regular running in the sterntube.
HYDROX BIO 220 is recommended for use particularly where problems of oil leakage past the aft seals is being experienced. In the majority of cases a significant reduction in leakage rate can be achieved.
HYDROX BIO 100
Biodegradable unsaturated emulsifiable sterntube oil ISO 100
Part no. 10100
HYDROX BIO 150
Biodegradable unsaturated emulsifiable sterntube oil ISO 150
Part no. 10150
HYDROX BIO 220
Biodegradable unsaturated emergency grade emulsifiable sterntube oil ISO 220
Part no. 10220
HYDROX BIO 68
Biodegradable unsaturated emulsifiable sterntube oil ISO 68
Part no. 10168
Synthetic non-emulsifiable ester based lubricant
ECOSTERN SMX is an environmentally acceptable lubricant (EAL) based on synthetic esters which meets the detailed ecological definitions and requirements laid down in Vessel General Permit (VGP). Through the careful selection of esters and additives, ECOSTERN SMX demonstrates improved hydrolytic stability (resistance to breakdown by water in high temperature situations) and better oxidative stability (longer fluid life) compared to competitor oils.
This product does not emulsify with water and is intended for owners who prefer to separate off any excess water. It is necessary to remove free water in order to avoid corrosion on standing or damage to the bearing which is not protected from the danger of low viscosity free water. This product does not reduce oil transfer across the seals or provide leak reduction where seals may become damaged
ECOSTERN SMX 100
Biodegradable fully saturated non-emulsifiable sterntube oil ISO 100
Part no. 10931
Mineral based emulsifiable lubricant
HYDROX and NEOX are ranges of mineral based sterntube lubricants which provide excellent wear and corrosion protection. HYDROX and NEOX will absorb sea or fresh water entering the sterntube to form a fluid emulsion. This reduces the risk of free water being present and continues to provide the required lubrication and corrosion protection. Conventional oils do not emulsify in the same way and tend to separate, exposing components to free water and potential wear damage.
HYDROX 550 is a SAE 30 lubricant which is generally recommended by the bearing and seal manufacturers for regular running in the sterntube.
HYDROX 21 is recommended for use particularly where problems of oil leakage past the aft seals is being experienced. In the majority of cases a significant reduction in leakage rate can be achieved.
NEOX 8000 is recommended for use when compression or older face seals are fitted with non-circulatory oil feed systems.
NEOX D is a grease-like lubricate recommended for use in some compression seals.
