CASTROL Tribol GR 1350-2.5 PD
Industrial Greases and Pastes
High performance bearing grease based on lithium soap with an extremely high viscosity base oil containing Castrol's advanced MicroFlux Trans (MFT) additive package.
Tribol GR 1350-2.5 PD is especially suited for rolling and sliding bearings in dusty and humid environments. It builds a stable grease collar at the bearing edges, supporting the seals to prevent penetration of dirt, water and other contaminations. Tribol GR 1350-2.5 PD enables a hydrodynamic lubricating film even at low speeds.
Developed for the lubricantation of anti-friction and plain bearings running at low speeds which require extremely high oil viscosity, or operate 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 harbours, and on ships and drilling platforms
- Yaw gear on wind turbines
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 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 conventional lubricants, the tribopolymers formed by MFT are long-chained compounds with excellent lubricity and adhesion. This means that the load carrying area is improved and that a hydrodynamic lubrication film is easier to maintain. This unique physio-chemical reaction achieves a non-sacrificial micro-smoothing of the friction surfaces.
