Castrol Optigear Synthetic™ 800 Range (previously called Tribol™ 800) synthetic gear oils have been developed for the lubrication of heavily loaded gears, bushings and bearings which may operate over a broad range of temperatures from ambient to elevated temperatures (>80°C/176°F). They are particularly intended to extend the service life of both lubricant and machine parts where unusually high operating and oil reservoir temperatures are encountered. The high performance characteristics of Optigear Synthetic 800 are achieved with select polyalkyleneglycol (PAG) based synthetic fluids. They feature chemical and thermal stability, high viscosity index, water solubility, and compatibility with metals and elastomers most commonly used in machine construction. The naturally high resistance to oxidation of the synthetic based fluid is further enhanced by inhibitors. Corrosion protection is very effective even in the presence of water. Also, a package of high performance additives acts in combination for superior anti-wear and Extreme Pressure (EP)
The Optigear Synthetic 800 range is especially suited to reservoirs and circulation systems operating at high temperatures because of heat generated in severe service or high temperatures in the application. Optigear Synthetic
800 are intended for all types of heavily loaded gears including spur, bevel and worm gears. Although well suited for all types of gearing and bearings, the Optigear Synthetic 800 range is particularly effective in controlling wear and reducing friction between sliding surfaces. In addition, they possess a high degree of affinity for cupric metal alloys
Shear stability - the synthetic base offers high viscosity index (VI) without the addition of VI improvers. In service, VI improvers can shear, lowering oil viscosity and reducing protection critical for gear sets and bearings. The
naturally high VI of Castrol Optigear Synthetic 800 assures full protection for components over a wide range of operating temperatures, speeds, and load conditions.
Long life, extended drain intervals are possible because of the natural aging and oxidation resistance of the synthetic base fluid. Advanced Castrol Optigear Synthetic lubrication technology forms friction-fighting, anti-wear
films that can significantly reduce local operating temperatures as gear teeth or bearing surfaces come into contact.
More protection for components in severe service. The extended EP performance of Optigear Synthetic 800 offers protection beyond the capabilities of conventional petroleum oils.
Wear protection under conditions of extreme temperature fluctuation and high loads. High efficiency and lower oil temperature, especially in worm gear units.
High corrosion protection of cast and steel surfaces through special additive packages, even in the presence of water.
Compatibility with non-ferrous metals through well-formulated synergistic additives.
Potential energy savings as a result of a lower coefficient of friction.
Reduction of maintenance costs as a result of significantly increased life of the lubricant.
