I. Features Advantages of Castrol Optigear Synthetic 800/460

• Optigear Synthetic 800/460 synthetic gear oil has 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 up to 160 °C and for up to 200 °C for short periods.
• It 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 800/460 is 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 800/460 is particularly effective in controlling wear and reducing friction between sliding surfaces. In addition, it possesses a high degree of affinity for cupric metal alloys.
• The high-performance characteristics of Optigear Synthetic 800/460 are achieved with select polyalkyleneglycol (PAG) based synthetic fluids. This product features 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 base 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) performance.
