Castrol Optigear 1100 Range gear oils (previously called Tribol 1100 Range) with the TGOA (Tribol Gear OilAdditive) additive system, represent a significant advancement in gear oil technology. Developed for service in enclosedgear drives, journals, and antifriction bearings, Optigear 1100 gear oils are typically used where heavy and shock loadconditions prevail.Optigear1100 gear oils are manufactured from the highest quality petroleum base oils. Blended into this oil is the latestdevelopment in the field of surface improving additives designated TGOA. TGOA is an oil soluble additive packagedesigned to reduce friction while providing surface protection and improvement. The TGOA additive package offerssuperior performance because of its unique action on frictional surfaces.The TGOA additive package is activated by high specific loads and corresponding temperatures causing a chemicalphysicalreaction. This results in an equalization of surface roughness without creating abrasion. Therefore, surfaceroughness is reduced without the loss of surface material.The results of the TGOA additives can be compared with a rolling process in the micro-range. The surface roughness isgradually levelled and smoothed. Through smoothing of the working surfaces, the loads are distributed over increasingareas and the actual load carrying area is enlarged.
If surface roughness peaks redevelop because of shock loads or stop-and-go operation, the TGOA additive package isautomatically reactivated. Surface roughness is again smoothed and lubrication optimized.Optigear 1100 range has passed the Cincinnati Milacron Thermal Stability Test. This test evaluates copped and steelcorrosion and oxidation stability. Optigear 1100 gear oils are approved as P 74, P 59, and P 35 for the ISO 220, 320, and460 grades respectively. These oils exceed minimum requirements according to DIN 51517 Part. 3 for CLP gear oils.Castrol Optigear Synthetic X is based on synthetic hydrocarbons and a special plastic deformation (PD) andsurface improvement additive package.The additive package, when activated by high specific loads and corresponding temperatures, helps to equalizesurface roughness without creating abrasion leading to the surface improvement (plastic deformation.)Optigear Synthetic X is a CLP-HC gear oil (according to DIN 51502) and exceeds the minimum requirementsaccording to DIN 51517, part 3, CLP gear oils.ApplicationOptigear Synthetic X may be used in spur gear, bevel gears or planetary gear units and in heavy loaded gearunits, e.g. wind turbine main gears. It is also suitable for the lubrication of oil-lubricated rolling bearings.Depending on the specific application, Optigear Synthetic X may be used in an operating temperature range from-30 °C to +95 °C.
