Your requirements – our solution

Klüberbio EG 2 oils are readily biodegradable gear oils based on synthetic ester oil.
They contain >90 % of renewable raw materials and comply with 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 (Vessel General Permit).

Klüberbio EG 2 oils show a high shear stability and form a strong hydrodydamic oil film even when subject to high loads. They have a high scuffing resistance, protecting gear teeth reliably against fretting damage even at high peak loads.


Klüberbio EG 2 oils were developed for the lubrication of ships’ gearboxes, particularly for thrusters and rudder propellers. All
the leading manufacturers of thrusters have tested and approved these oils. Please contact Klüber Lubrication or the manufacturer of the swal or thruster for technical consultation on your specific seallubricant combination.

Klüberbio EG 2 oils can also be used for the lubrication of openrunning drive and conveyor chains, e.g. in installations and machines in agriculture, forestry and water resources industries as well as for horticultural appliances.

Application notes

In general, our rapidly biodegradable high-performance gear oils are miscible with mineral oils and synthetic hydrocarbons. 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 cleaning the lube points or flushing the gear with the Klüberbio EG 2 oil to be used.

The Klüberbio EG 2 oils need to be approved by the OEMs of the equipment. In case the oil has not yet been approved or the equipment’s specification has been changed – e.g. type, design or material of the sealing – 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 (e.g. maximum admissible water content in the oil) with the component under conditions similar to practice.
