New stern tube oils offer longer oil service life and reduce lubricant consumption

Eco-friendly lubrication of fixed-pitch and controllable-pitch propellers

Munich, September 9th, 2014 – Even very small oil leakage through propeller water-side seals caused by operational wear, accidents or incorrect operation can entail a high environmental impact when mineral oil-based lubricants are used. Klüber Lubrication developed the Klüberbio RM 2 series of biodegradable synthetic stern tube oils especially for the lubrication of propeller bushes and shaft seals in fixed-pitch and controllable-pitch propellers. These special oils contain more than 90 percent of renewable raw materials and their biodegradability is at least 60 percent according to the OECD 301 F test. Klüberbio RM 2 oils are non-toxic to marine organisms. They bear the European Ecolabel and comply with the requirements of 2013 Vessel General Permit of the Environmental Protection Agency (EPA) (Appendix A of the US EPA VGP (Vessel General Permit) 2013).

"Our new stern tube oils show good resistance to oxidation and hydrolysis as well as thermal stability", says Dirk Fabry, Business development Manager, Business Unit Marine, Oil&Gas from Klüber Lubrication. "This results in extened oil service life and reduced lubricant consumption and disposal costs."

Additionally, Klüberbio RM 2 oils offer a good viscosity-temperature behaviour, which facilitates start-up of propellers at very low temperatures. It forms a thick lubricating film at elevated temperatures ensuring good wear protection. Klüberbio RM 2 oils are miscible with stern tube oils based on mineral oil, hence easy changeover is possible.

Standard elastomers like NBR and FKM are resistant to Klüberbio RM 2 oils. The new stern tube oils are approved by leading propeller shaft seal manufacturers.
