Saturated ester based biodegradable lubricant for gearboxes in windmills
BioGear WM is a premium synthetic biodegradable gear oil designed to provide exceptional anti-wear/extreme pressure (AW/EP) protection and corrosion control under the most adverse conditions. The product is specially formulated for lubricating wind turbine gearboxes for effective operation and long service life. It has a high viscosity index that minimizes changes in viscosity at elevated temperatures, while ensuring good low temperature fluidity of the lubricant for cold temperature operation. It also offers good micropitting resistance and high scuffing load. Due to its saturated ester base biodegradable composition it is environmental friendly and good for use in sensitive areas such as at open sea.
