Castrol OptipitTM is a lithium soap-based grease with an extremely high viscosity base oil containing the advanced Microflux Trans (MFT) additive package. The Microflux Trans additive technology provides optimum wear protection and an extremely low coefficient of friction even under extremes of pressure, vibration, shock loads, at high or low speeds or varying micro-smoothing of the friction surfaces.
Under severe load, components of the Microflux Trans additive combination are activated and diffuse into the surfaces, initiating an improvement of their friction characteristics through plastic deformation. The organic reaction products become a component of the tribopolymer system. Unlike the case with conventional lubricants, the tribopolymers formed by Microflux Trans are long-chained compounds with excellent lubricity and adhesion. The load carrying area is improved, a hydrodynamic lubrication film is easier to maintain. This unique physio-chemical reaction achieves a nonsacrificial micro-smoothing of the friction surfaces.
Applications: Optipit is especially suited for rolling and sliding bearings in dusty and humid environments and builds up a stable grease collar at the bearing edges, supporting the seals to prevent penetration of dirt, water and other contaminations. Optipit enables a hydrodynamic lubricating film even at low speeds.
Developed for lubrication of anti-friction and plain bearings running at low speeds requiring extremely high oil viscosity
and operating in wet and dusty atmospheres found in applications such as:
mining, especially open-pit mining
the steel industry/tube mills under heavy shock loads and vibration
equipment exposed to sea water, in harbors, and on ships and drilling platforms
