Castrol Tribol™ GR 1350-2.5 PD (previously called Optipit™) is a lithium soap based grease with an extremely highviscosity 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 frictioneven under extremes of pressure, vibration, shock loads, at high or low speeds or varying micro-smoothing of the frictionsurfaces. Under severe load, components of the MFT 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 conventionallubricants, the tribopolymers formed by MFT are long-chained compounds with excellent lubricity and adhesion. Thismeans that the load carrying area is improved and that a hydrodynamic lubrication film is easier to maintain. This uniquephysio-chemical reaction achieves a non-sacrificial micro-smoothing of the friction surfaces.
Tribol GR 1350-2.5 PD is especially suited for rolling and sliding bearings in dusty and humid environments. It builds astable grease collar at the bearing edges, supporting the seals to prevent penetration of dirt, water and othercontaminations. Tribol GR 1350-2.5 PD enables a hydrodynamic lubricating film even at low speeds.
