KLUBERBIO EG 2

Environmentally compatible, synthetic high-performance gear oils.

Klüberbio EG 2 oils are ultimately biodegradable gear oils based on synthetic ester oil. They contain ≥90 % of renewable raw materials.

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 achieve 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 2013 VGP (Vessel General Permit).

Klüberbio EG 2-150 also complies 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.

Klüberbio EG 2 oils were developed for the lubrication of ships’ gearboxes, particularly for thrusters and rudder propellers. Leading manufacturers of thrusters and propeller shaft seals have tested and approved these oils.
Please contact Klüber Lubrication or the manufacturer of the seal or thruster for technical consultation on your specific seal-lubricant combination.
Klüberbio EG 2 oils protect rolling elements effectively against wear and pitting, thus complying with the requirements of rolling bearing manufacturers for highly loaded, large rolling bearings in pod drives.
Klüberbio EG 2-68, 100 and 320 oils can also be used for the lubrication of open-running drive and conveyor chains, e.g. in installations and machines in agriculture, forestry and water resources industries as well as for horticultural appliances.
In general, our completely 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 oil to be used needsto be approved by the OEMs of the equipment. In case the oil is not 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.

Complies with the requirements for environmentally friendly lubricants (according to VGP 2013 Annex A)
It is completely biodegradable. It is non-toxic to marine organisms; thus reducing the environmental impact in case of leakage.
Klüberbio EG 2 oils have high friction resistance and protect gears against wear even at high peak loads.
Standard NBR and FKM elastomers from leading manufacturers of propeller shaft seals are resistant and approved to Klüberbio EG 2 oils, preventing leaks and dirt.
