Gear oils

Keeping your gearbox operating reliably and efficiently

As marine gear units are subject to the highest operational requirements, design adjustments, new manufacturing processes and production technologies call for selection and use of the highest performance lubricants.

Klüber Lubrication high-performance gear oils provide long-term protection of gear units and enable increased service life compared to conventional mineral-based enclosed gearbox oils.

Reduce your maintenance service intervals with Klübersynth GEM 2, GEM 4 and the Klüberbio EG 2 gear oil series enabling service lifetimes 3 to 4 times longer than standard oils. The products' synthetic base oils offer excellent ageing and oxidation resistance and provide a high scuffing load capacity to protect gear flanks against damage even under high loads. The low friction coefficient of high-performance gear oils can also improve gear efficiency while saving costs and reducing CO2 emissions.

We recommend Klüberbio EG 2 oils for the lubrication of rudder propeller and thruster gear drives. They are rapidly biodegradable, and do not bio-accumulate which considerably reduces their environmental impact in the event of leakage. Klüberbio EG 2 oils comply with the standard for Environmentally Acceptable Lubricants as defined in Appendix A of the 2013 Vessel General Permit issued by the United States Environmental Protection Agency.

Selected elastomers made of NBR and FKM are compatible and approved for use with Klüberbio EG 2 oils to prevent leakage and contamination.
