Your requirements – our solution

Klüberbio RM 2 oils are completely biodegradable oils for stern tubes based on synthetic ester oil showing good ageing and oxidation stability. As the lubricants are readily biodegradable and contain carefully selected raw materials, oil loss or leakage are less dangerous to the environment.

Klüberbio RM 2 oils contain > 90 % of renewable raw materials and bear the European Ecolabel.

The EU Ecolabel is a label of environmental excellence that is awarded to products and services meeting high environmental standards throughout their life-cycle: from raw material extraction, to production, distribution and disposal.

Attaining EU Ecolabel certification provides ship owners and/or operators with independent assurance that the product achieves the U.S. EPA’s requirements for classification as an Environmentally Acceptable Lubricant (EAL). Therefore, these high-performance lubricants meet the biodegradability, minimally toxic, and non-bioaccumulating standards set in Appendix A of the U.S. EPA’s VGP.

Klüberbio RM 2 oils show a high shear stability and form a strong hydrodynamic oil film even when subject to high loads.


Klüberbio RM 2 oils were developed for the lubrication of
propeller bushes made of white metal and propeller shaft seals.

Klüberbio RM 2 oils are tested and approved by all leading propeller shaft seal manufacturers.

Application notes

In general, Klüberbio RM 2 oils are miscible with mineral oil based stern tube lubricants. However, a miscibility test should be performed in order to totally rule out the possibility of an incompatibility between different additives. Prior to changeover, we recommend flushing the stern tube with the Klüberbio RM 2 oil.

Klüberbio RM 2 oils need to be approved by the OEMs of your propeller shaft seal or bearing. In case the oil has not yet been approved or the specification of the seal or bearing has been changed – e.g. type, design or material – we recommend consulting the OEM prior to the oil change.

Owing to the many different elastomer compositions of seals we recommend – prior to series application – checking the compatibility and other influencing factors that are relevant for the application with the component under conditions similar to practice.
