GEAR OIL KLUBERBIO EG2-68 CST
- Product group:
- Product number:
KLÜBERBIO EG 2-68 is a synthetic Environmentally Acceptable Lubricant (EAL) specially formulated to protect your gears. By providing high scuffing resistance, it safeguards your gear teeth against fretting damage — even at high peak loads.
The offshore and maritime industry employs the use of a variety of gears that are subject to much scuffing and pitting --- sometimes in harsh and difficult conditions. To protect your gear teeth reliably against the damage these factors could cause, KLÜBERBIO EG 2-68 offers high scuffing resistance, reducing fretting damage, even at high peak loads.
Moreover, KLÜBERBIO EG 2-68 provides high shear stability, forming a strong hydrodynamic oil film even when taking on big loads. This makes it a good choice for the safe and enduring operations of your gear.
Formulated with synthetic ester oil, KLÜBERBIO EG 2-68 is biodegradable and non-toxic to our marine environments, reducing the harm that would arise in an event of a leakage. It contains over 90% renewable raw materials and meets the U.S. EPA's 2013 VGP (Vessel General Permit)'s biodegradability, minimally toxic, and non-bioaccumulating standards.
Moreover, KLÜBERBIO EG 2-68 has obtained the European Ecolabel, affirming its sound formulation that meets high environmental standards throughout its life cycle, from raw material extraction to production, distribution and disposal.
Standard NBR and FKM elastomers of leading propeller shaft seal manufacturers are resistant to and hence approved for use with KLÜBERBIO EG 2-68, as they successfully prevent leakages and contamination from impurities.

Safety Data Sheet (SDS)
Directions for use
KLÜBERBIO EG 2-68 is ideal for the lubrication of ships' gearboxes, particularly for thrusters and rudder propellers. It is tried, tested and recommended by leading manufacturers of thruster and propeller shaft seals.
Given its wear and pitting protection properties, KLÜBERBIO EG 2-68 complies with the requirements of rolling bearing manufacturers for use on highly loaded, large rolling bearings in pod drives.
KLÜBERBIO EG 2-68 is generally miscible with mineral oils and synthetic hydrocarbons. However, please conduct a miscibility test to safely and completely rule out the possibility of incompatibility between different additives.
Before the changeover, clean the lube points or flush the gear with the KLÜBERBIO EG 2-68 oil to be used. Please note that KLÜBERBIO EG 2-68 needs to be approved by the OEMs of the equipment — if it is not, or the equipment's specification has been changed, consult the OEM prior to changing the oil.
