CASTROL TRIBOL GR 1350-2.5 PD
Castrol Tribol™ GR 1350-2.5 PD (previously called Optipit™) is a lithium soap based grease with an extremely high viscosity base oil, containing the advanced MicroFlux Trans (MFT) additive package. It is especially suited for rolling and sliding bearings in dusty and humid environments, building a stable grease collar at the bearing edges to support seals against dirt, water, and other contamination. Tribol GR 1350-2.5 PD enables a hydrodynamic lubricating film even at low speeds, and is developed for anti-friction and plain bearings running at low speeds requiring extremely high oil viscosity, or operating in wet and dusty atmospheres — such as open-pit mining, the steel industry/tube mills under heavy shock loads, equipment exposed to sea water in harbours and on ships and drilling platforms, and yaw gear on wind turbines.

KEY FEATURES
| •Water and dirt repellent – the grease is still effective in adverse environments |
| •High load bearing capacity – enables the extension of operating periods even under high loads whilst still maintaining optimum wear protection |
| •Establishes a protective layer of MFT – effectively increasing the load bearing area, reducing unit pressures, operating temperatures and wear, and increasing service life of both parts and lubricant |
| •Improved bearing surfaces for longer service life result from the ‘running in’ effect of MFT |
| •Extremely low coefficients of friction – energy savings and reduced noise levels |
| •Good adhesion due to high oil viscosity – the film coating stays on the surface |
| •Reduction of running-in period |
