Premium synthetic oils formulated specifically for use in wind turbine gear box applications but it can be used for all types of enclosed gears – including heavy and shock-loaded gears and bearings where EP properties are required. High load-carrying capacity Superior micropitting protection Reduces friction between moving parts Good filterability Excellent suitability for bearing lubrication ideal lubricant for gear boxes where large changes in temperature and humidity cannot be controlled.Optigear Synthetic CT is based on synthetic hydrocarbons and a special additive package designed to perform in the most challenging of applications. Its inherent high viscosity index coupled with advanced gear oil additives make it an ideal lubricant for gear boxes where large changes in temperature and humidity cannot be controlled. Optigear Synthetic CT series may be used in spur, bevel or planetary gear units and in heavy loaded gears, e.g. wind turbine main gears. It is also suitable for the lubrication of oil-lubricated rolling element bearings.
