KLÜBERBIO RM 2-100 is a synthetic Environmentally Acceptable Lubricant (EAL) designed to support and protect your stern tubes. Offering good ageing, oxidation, and shear stability, it forms a strong hydrodynamic oil film even under high loads, empowering your parts to operate reliably.

Product information

Stern tube lubricants deal with a unique set of challenges that include working under high loads across a wide range of conditions and needing to be environmentally safe for their inevitable leaks into the sea. KLÜBERBIO RM 2-100 was formulated to handle these demands — helping your propellor shafts stay high-performing and well-protected even in rough conditions.

Built with synthetic ester oil, KLÜBERBIO RM 2-100 exhibits powerful ageing and oxidation stability, minimising the risk of any undesirable increases in viscosity levels. Supported by excellent shear stability, it is empowered to form a strong hydrodynamic oil film even under high loads. A durable hydrodynamic lubricant film is crucial to protecting your parts and bearings from damage caused by intense, sustained friction and/or extreme temperatures.

KLÜBERBIO RM 2-100 also contains over 90% renewable raw materials and is biodegradable and non-toxic to marine life in the event of contact with the seawater. As a testament to its environmental excellence, it bears both the European Ecolabel and the certification of Environmentally Acceptable Lubricant (EAL) by the US Environmental Protection Agency.

KLÜBERBIO RM 2-100 is compatible with various FKM elastomers from leading propeller shaft seal manufacturers, making it a safe and trusted lubricant solution for reduced leakage and contamination.

Directions for use

KLÜBERBIO RM 2-100 is suitable for lubricating propeller bushes made of white metal and propeller shaft seals. Tested and approved by all leading propeller shaft seal manufacturers.

Though it is generally miscible with stern tube oils based on mineral or ester oil, we recommend that you still perform a miscibility test beforehand to completely rule out the possibility of any incompatibility between different additives.

Please ensure that KLÜBERBIO RM 2-100 is approved by the OEM of your propellor shaft seal or bearing. If it is not, or the seal or bearing’s specification has been changed, consult the OEM before changing the oil.
